Stem Cell Viability

Stem cells are the root cells that are found in majority of multi-cellular organisms

. Stem cells are known for their ability to mutate in any of type of tissues and cells. Stem cells generally are of two types, adult stem cells and embryonic stem cells. Owing to their ability to mutate into any form of cells and tissues, they are widely used in the treatment of various fatal diseases such as cancer.

By acting as effective drug delivery systems, they have also been able to crack the effective blood barrier in the brain and are hence able to treat the various neurological disorders including Parkinsons disease which was other wise difficult to treat with the help of enzymes. Owing to these benefits of stem cells, scientists are promoting stem cell growth on a large scale. Research has found that several hormones promote stem cell growth.

Ever since the research in stem cells gathered momentum, much has been said about the viability of the stem cells. Studies indicate that the Transient Warming Events (TWE) heavily affect the stem cell viability. This mainly happens before the transplantation process when normal cryogenic processing equipment is used to prepare stem cell units.

Due to the normal processing equipment, the stem cells at the time of their transfer to quarantine freezer and controlled rate freezer are exposed to the surrounding air. This leads to a considerable loss in the viable colony forming cells. Owing to these factors, scientists are developing ways through which they can increase the stem cell viability.

Owing to the numerous benefits that stem cells possess, it is important to encourage the research in the arena of stem cells and promote cell culture. However, this is not that easy, as it seems, as it requires huge number of samples and proper protection from the environmental conditions.
