Stem cells will receive from uterine pipes

The Brazilian scientists suggested to use the fabrics received at amputation of a uterus, for receiving stem cells, reports the Air Force. Work of experts from São Paulo University (University of Sao Paulo) was published in The Journal of Translational Medicine.

Researchers could allocate and multiply on a nutrient medium multipotentny stem cells from fabrics of uterine pipes which leave together with a uterus or at surgical sterilization. Further these stem cells can be used for receiving hryashchevy, bone, fatty and muscular fabrics.

According to researchers, opening can be used for development of new methods of treatment of such diseases as arthritis, and also as a source of mezenkhimny stem cells. These cages will help with studying of mechanisms of development of infertility at women.


The previous researches showed possibility of receiving multipotentny stem cells from various fabrics of an organism (fatty, muscular, hryashchevy, bone and others). Making comments on work of the Brazilian scientists, the employee of Royal college of London (Kings College London) Stefen Minger (Stephen Minger) noted its ethical value. However he added that receiving stem cells from a fatty fabric or a marrow is more available and less travmatichny for the person.

Controllable clinical researches

Use of an umbilical blood in the future while vaguely. There is a number of promising researches, but the checked ways of treatment with use of an umbilical blood are described here. The bank of the umbilical blood, declaring that he knows precisely how stem cells in the future will be used, isn't honest with you.
Stem cells can recycle heart after the suffered heart attack


1. Treatment Potential treatment of illnesses of heart is based on ability of stem cells to restore a pericardium.
2. A cellular injection Stem cells are entered through a catheter into heart directly right after a heart attack or when heart very much weakened and became inactive to swing blood properly.
3. New life Results show that stem cells can treat the damaged fabrics but while there is no confidence of, whether there are stem cells cells of the adult person or they stimulate division and regeneration of already existing cells of heart.

On March 18 2011 — Researchers of stem cells showed for the first time that the stem cells entered into increased heart, reduced its volume, a cicatricial fabric and improved functioning of the struck sites of heart. The received results of the small experiment which has been carried out in Interdistsiplinarn institute of stem cells (Interdisciplinary Stem Cell Institute) at Miami university, Miller's (University of Miami Miller School of Medicine) medical school, are published on March 17 in Circulation Research release: Journal of the American Heart Association.?? “Even at early stages of this research,” Joshua M. Her, the senior head of research and director Interdistsiplinarnogo of institute of stem cells speaks, ”its results sound is promising for more than five


million Americans with the increased heart because of the suffered heart attack.” Such patients are subject to risk of premature death, are invalid and need frequent hospitalization. Traditionally treatment is carried out in two directions — lifelong acceptance of drugs and surgical intervention, for example, a heart transplantation.

On October 12 2010: Scientists declared on Monday that they entered into Friday stem cells to the patient with the damaged spinal cord, having given that began to first-ever clinical research of therapy by stem cells of a human embryo.

The patient was on treatment in Shepherd Center, the center of violations back and a brain in Atlanta.

In spite of the fact that the experience which is carried out by Geron Corp. Menlo Park, California, was at early stages — on purpose to investigate treatment about its safety — this event represents the first step in research of embryonic stem cells, this corporation already for many years studied cellular potential in treatment of damages back могзга, diabetes and a number of neurodegenerate diseases.

The bone can do of fat


The American scientists developed an improbable method of restoration of a bone fabric. They allocated stem cells from a fatty fabric and grew up from them a bone.
Methods of restoration of a bone fabric which are used now, are imperfect. Scientists managed to create a new reliable method of cultivation of a bone from the stem cells received from a fatty fabric.

Scientists hope that for restoration of a bone fabric the doctor will need to receive a fatty fabric of the patient, to allocate stem cells and to place them there where it is necessary to grow up a bone.

Unlike traditional methods which are used for restoration of the bones, the new method allows to grow up a bone in short terms and more quality.

What is the marrow?




The marrow is the porous fabrics being in some bones. It plays important role as contains the special cages known as stem cells.

Stem cells develop other special cages which carry out important functions. Stem cells in a marrow develop three important types of blood little bodies:
rasny blood little bodies which transfer oxygen on an organism
white blood little bodies which help to struggle with infections
plates which help to stop bleedings.

Anna Kovalchuk kept an umbilical blood in the Russian bank "Gemabank" - "Gemafond's" partner

On April 30, 2010 the well-known actress, a star of series "Secrecy of the investigation" and "The master and Margarita", the leading actress of Lensovet Theatre, Anna Kovalchuk gave birth to the son. In July we phoned to Anna, and she told about the pregnancy, childbirth, son Dobryn, the daughter Gold, about daily cares and plans for the future.



Anna, tell, please, about day when you learned about pregnancy? How it was?


We came back from the South. I made the test and in spite of the fact that it showed nothing, took it with myself. When arrived home – looked once again, saw the second stripe and understood that there was a miracle which we with the husband waited some months. And, frankly speaking, already started to worry that pregnancy doesn't come in any way.



You conducted what way of life during pregnancy? How actively worked, went to have a rest?



I went to have a rest to Finland by the car. Tried to conduct an active way of life. But my kid persistently dictated to me that especially активничать it is not necessary. I very quickly was tired, was compelled to be at home. Seldom went shopping, because when came to do shopping, to me at once it became stuffy, heavy, it would be desirable to sit down and not to move. Therefore I decided that the most part of time I will spend at home. Sometimes we left on a visit to friends, were charged from communication with them by positive power.



Than your condition differed from the first pregnancy?



Pregnancy were absolutely different. And children turned out different. The first pregnancy passed very quickly, literally on the run. I was very happy that the daughter in a tummy, all the time with me. In the second time I would like to see the kid as soon as possible. Because of unimportant health, childbirth I looked forward.



You got ready for childbirth, or how to skilled mother, it wasn't necessary for you and you completely relied on the knowledge?



Yes, I relied on the knowledge, on the nature, specially for childbirth didn't prepare and, maybe, in vain. At the time of delivery I incorrectly breathed, and the midwife had to explain me all subtleties of breath in process. I do not know, whether I forgot partially, how it is necessary to breathe, whether and in first labor did it incorrectly. During pregnancy I read special books, magazines, remembered stages of childbirth. But now it is sure that occupations at school for pregnant women should be visited surely.



As all mothers you worry about health of the children. Tell, how you learned about stem cells of an umbilical blood and why made the decision of them to keep.



To me was told about it by my schoolmate. The first time about such service I heard from it. Then began to read about stem cells in magazines. My colleague on theater kept cells of the child, and told me that it is very necessary procedure. I with pleasure used this service.

During pregnancy future child shares the stem cells with mother


The group of the American scientists of the Medical center Taftsa (Boston, the USA) found out that in an organism of future mother cages of a fruit of three different types circulate. So, studying an organism of mice on late terms of pregnancy, in easy rodents they found cages of a placenta, immune system and stem cells of a fruit. It induced scientists to studying of the mechanism of migration of stem cells of future child, and action of these cages on an organism of mother.


Results of the researches which have been carried out under the direction of doctor Diana Bianka, were published in Biology of Reproduction's Papers-in-Press. Scientists managed to find existence of the mixed population in blood of future mother of the child: cages трофобласта, mesenchymal stem cells and cages of immune system.

Trofoblasta are placentary cages which provide access of a fruit to nutrients. Mesenchymal stem cells - type of cages which can turn into fat, a cartilage or cages of a bone fabric. Researchers assume that these cages (and also immune cages) a fruit in blood of mother are capable to help not to perceive to immune system of the woman a fruit as alien "agent" in an organism and not to "attack" it. Detection of cages трофобласта and immune cages in parent lungs should help further researches with this area. In particular, scientists hope to reveal the mechanism of emergence of complications during pregnancy, and also effect of restoration at damage of parent bodies which allegedly arises thanks to existence of mesenchymal stem cells of a fruit.

Using the latest methods which allowed to receive enough information from only 80 stem cells, scientists can come nearer now to understanding of all complexity of such process as pregnancy, and it is better to understand mechanisms of migration of stem cells. Research of the American scientists from the Medical center Taftsa develop and confirm opening which made before their colleague of New York and Los Angeles. They found out that stem cells of a fruit migrate in the struck bodies of future mother and help them with restoration.


According to the director general of the Ukrainian Family bank of an umbilical blood "Gemafond" of Andrey Lakhturov: «Unique properties of stem cells on maintenance of self-updating of bodies and fabrics of our organism made them the most valuable material for studying. Research of stem cells will allow to learn better principles on which our organism functions and to open ways of providing the person health and longevity. Thus already today stem cells are used at treatment more than 100 diseases, the most frequent on application among which is the group of oncological diseases».

Opening was made by scientists of the Center of researches of respiratory diseases at University college of London. Experts managed to change stem cells of a marrow in such a manner that they became capable to move on an organism, to find cancer tumors and to destroy them. Killing of cancer cages occurs to the help of TRAIL protein (TNF-related apoptosis-inducing ligand) which starts in them process апоптоза.

Action of deckman cages murderers was successfully tested on laboratory cellular cultures and live mice. In the first experiment genetically changed stem cells destroyed cages of cancer tumors of lungs, a mammary gland, a uterus neck, and also skvamozny cages. During the second experience scientists did hypodermic injections of new stem cells to rodents therefore tumors in their mammary glands decreased by 80 %. Intravenous injections allowed to destroy about 38 % of metastaziruyushchy pulmonary tumors at mice.

Results of experiments look very encouraging. However, according to authors of research, testing of genetically changed stem cells in public will take place not earlier than in two years.

AIDS are going to treat stem cells



The stem cells of blood created in vitro, can suppress completely HIV, scientists from the Californian university found.

Earlier scientists revealed a receptor by means of which cages of immune system distinguish and destroy cages with HIV infection. In a human body not enough such receptors.

Microbiologists could clone them, and then simulated stem cells of human blood with the maintenance of the necessary receptor, transfers Today referring to Likar.

Having placed these cages in vilochkovy gland of laboratory animals, scientists found out that artificial stem cells actively participate in immunity formation against HIV and suppress a virus. Scientists count that this opening will help to create methods of treatment of HIV and AIDS.

As reported MIGnews.com.ua, about 20 % of Ukrainians, patients HIV/AIDS, came up against a situation when to them refuse medical care. As showed research, medical workers don't support patients more often, and subject them to discrimination. So, 28 % of respondents faced discrimination, got support of 19 %.

What is the umbilical blood and why it to keep?


Recently service in collecting and storage of stem cells of an umbilical blood causes the increasing and big interest of scientists, doctors and, certainly, future parents. The last, as a rule, have a little truthful information about similar service which became available in Ukraine about five years ago. Let's try to understand: what is the umbilical blood and why it to keep.

By science it is proved that each kid is born with additional immunity on an illness case. It is a small amount of blood which remains in placenta vessels after umbilical cord cutting. Each milliliter of an umbilical blood — worth its weight in gold, after all this blood is improbably rich with invaluable stem cells.

About stem cells even the people who are very far from medicine already heard. But such information can be not absolutely correct. After all quite often mass media, wishing to draw of attention of readers, modifies medical value and experience of application of stem cells. So such stem cells and why physicians of the whole world advise to future parents them to keep?

Stem cells — it is an organism fundamental principle — the first and universal cages with which life of each of us began. They turn into any specialized cages in an organism — cells of a liver, heart, skin... From these cages in vitro it is possible to grow up practically any body.


Opening of properties of stem cells became the real revolution in medicine, having based a new era of «cellular medicine».

Today, with use of stem cells, new approaches to treatment of AIDS, a cancer, Alzheimer's disease, multiple sclerosis, Parkinson's illness, a myocardial infarction, a stroke and many other are developed. And existing already more than 20 years a technique of transplantation of a marrow (recognized «a gold standard» in treatment of many forms of leukoses) no other than intravenous introduction of krovetvorny stem cells.

The most widespread source of stem cells is the marrow, however its clinical use is connected with considerable difficulties. It, first of all, complexity of search of the compatible donor. Time necessary for this purpose, is sometimes measured for years whereas for the patient each hour matters. The second complexity is high cost of a sample of a marrow — about 40 000 euros.

Fortunately, scientists found out that the umbilical blood, as well as a marrow, contains stem cells, and in much bigger quantity and considerably the best quality. So today funic the shelter gains ground in treatment of a serious illness as alternative to a marrow, and behind official data rescued already about 15 000 lives.

Therefore in the developed countries of the world already more than 20 years ago were created and now banks of an umbilical blood successfully function, and storage of an umbilical blood of the newborns became for parents of these countries the same habitual business, as for us a payment for a garden, school or institute.

Modern technologies allow to keep in the conditions of ultralow temperatures stem cells infinitely long without loss of their properties, and, on a case, successfully to use them for the medical purposes.

Stem cells: conjectures and facts

The world from time immemorial feverishly looks for the miracle cures, capable to recover health, youth and beauty. For everything fantastic petty tyrants of type «are known bring that — I do not know that»: molodilny apples, water of life, youth elixir.

Some in hope to become краше even in a tub with boiled water ничтоже сумняшеся rushed. But fairy tales fairy tales and our science how came nearer to universal dream? About it we talk to the academician of National Academy of Sciences of Ukraine, the honored worker of a science and equipment, the winner of the state awards of the USSR, USSR and Ukraine, the doctor of medical sciences, the professor, the director of Institute of problems of a cryobiology and криомедицины NAN of Ukraine, the head of a chair of obstetrics and HGMU gynecology Valentin Ivanovich Grishchenko.

The mankind never will calm down
The mankind, probably, never will calm down, inventing the means prolonging life, health, youth. The cryobiology for certain already told a loaded word and about it?

Here possibilities at a cryobiology the very big. We in Ukraine and even in the world in many respects carried out pioneer functions. With stem cells we started to work still in 80х years when and names of it didn't hear many. Embryonic fabrics are used long ago for rejuvenation. By the way, in due time them entered to very known and influential people — to Brezhnev, Nixon, etc. Them it, of course, helped, but thus there was improbably big risk of infection through an abortive material — hepatitis C, for example. And the cryobiology is capable to make introduction of such preparations completely safe from the point of view of infections. To check that is entered, it is usually necessary some days, and during this time a material can decay.
