From first blood. Why freeze the stem cells of a newborn

According to statistics, the world each year there are around 200 million births, which destroyed about 20 thousand tons of umbilical cord blood. Although many doctors claim that it is extremely valuable. Today the propaganda for the preservation of umbilical cord blood began to develop rapidly, and, increasingly, young parents sign contracts for its cryopreservation in the future to have a kind of “insurance” for the child. It is believed that by using stem cells, included in its composition, it is possible to cure almost all diseases, including storm today — Oncology. How exactly does the umbilical cord blood and why carry out stem cell collection in hospitals — in the material Aephi.

About umbilical cord blood: why it retains and what it can cure

Easier reactions, less infections

According to doctors, the cord blood and resident stem cells is much better and healthier than other options blood. However, it often comes to its relevance in severe pathologies, for example, requiring a long serious treatment or a transplant. Pros own stem cells are:

  • Lower risk of transmission of latent viral infections
  • Lower frequency and severity of “graft vs. host”
  • No risk for the donor, etc.

Stem cells appear in the embryo from the very beginning of its formation in the womb. At first, they are the inner cell mass, which later form all tissues and organs. These cells divide very quickly and turn into cells of 350 different types. Their main property — to protect the body against various pathological microorganisms. Once they get the signal “attack”, it is sent to the lesion and turn into additional cells of the body or tissues that fight infection. Thus, they can help to restore balance and replace the damaged parts of the body.

But there is a downside: stem cells over time lose their efficiency and weakens, it becomes more difficult to deal with stress. And here to the aid can come prepared in advance replacement options.

Concentrate of the highest quality

Today is considered the most proper to produce blood sampling in infants. Because stem cells are still “fresh”, not deformed and not “tired”. The process of drawing blood from the umbilical cord, which, in principle, after the birth useless, since all its purpose is already fulfilled, is automated. So the doctors get concentrated formula, rich with stem cells of high quality. Cell viability after isolation, studies show, is 99.9%. For the procedure parents will be given a personal kit, which may be given by hand or delivered immediately to the hospital. Samples can even be transported to other regions about the conditions you will need to negotiate with the staff of the Cryobank.

Next comes the process of cryopreservation. Because the only way to keep the blood cells in the long term. If necessary will just have to defrost them and provide treatment. Experts say, treatment of such a tool in the world is held for 15 years. In the list of areas in which are struggling with the disease by such treatment:

  • Oncology
  • Hematology
  • Gastroenterology
  • Genetics
  • Gynecology
  • Dermatology
  • Cardiology
  • Neuroscience
  • Ophthalmology
  • Urology
  • Phlebology
  • Surgery
  • Endocrinology

Store cells

Before sending cells for storage, they should be ready for freezing. To do this, they placed in a special cryocontainers, which represent plastic bags or vials. What will be used is determined by the amount of material. Each sample of stem cells necessarily mark and use a unique code consisting of figures or strokes. Later, all the information recorded in a database and is duplicated, so that the probability of error is excluded by 100%.

Stem cells are smoothly-frozen in special plants that comply with optimal rates of cooling and can retain maximum viability.

Containers of cells after freezing are placed in separate boxes and immersed in liquid nitrogen. Thus they are protected from external influence so that they retain their activity over a long period of time. Electronic sensors, which are in storage, are responsible for controlling levels of nitrogen round the clock without interruption.

It is worth considering that this procedure is not cheap. Thus, the average cost of collecting cord blood is 70 000 rubles. And subsequent storage conditions determine different cryobanks, but on average, each month will cost 10 000 rubles.
