At the time of childbirth, the blood obtained from the umbilical cord is called as Cord Blood. After detaching the cord from the newborn baby, it is extracted from the fetal end of the cord. The cryopreservation of accumulated cord blood is carried out at -196°C & then piled up in a cord blood bank for future transplant. For the storage of umbilical cord blood stem cell and Umbilical Cord Mesenchymal Stem Cell, stem cell banking offers a unique opportunity for these.
Stem cells are undifferentiated cells which can be self renewed to an indefinite extent through cell division. These cells can also be distinguished into more mature cells with specific functions. Presently, the stem cells of Cord blood cells are used for the treatment of more than 75 hostile diseases.
This cryopreservation process accompanies many risks. For proper preservation and to avoid damage of stem cells, the solution concentration must be correct. The tissue cooling process must be at very less temperature otherwise the water in the tissues goes out and form ice in the extra cellular fluid space and as a result the ice could damage the cell membranes as a reflex action. Moreover, cellular dehydration may be caused due to water migration that can again lead to the damage of cells.
Before placing the cells into the deep freeze stage in liquid nitrogen, stem cells are freeze down through programmable steps in machines. On the other hand, the technique of Vitrification claims to cryopreserve the samples. This process is carried out to negate the damaging effects of ice crystal pattern. Before the process of cooling, the technique uses cryoprotectants to increase the viscosity and avoids the solution from the formation of crystallized ice.
The procedure for stem cell is an easy, non-persistent and painless one. The stem cells therapies are widely used for major treatments on demand. It hardly takes 10 minutes to bio-check the lives of your near and dear ones. Umbilical cord blood banking in India has been extended on to a large scale and the samples are stored at internationally accredited labs.
