how are steam cells preserved?
Answers
Preservation of stem cells is critical for both research and clinical application of stem-cell based therapies. Preservation permits development of cell banks with different major histocompatibility complex genotypes and genetically modified clones. As collection of stem cells from sources such as umbilical cord blood can be difficult to predict or control, the ability to preserve cells permits the banking of stem cells until later use in the research lab or clinical application. The ability to preserve cells permits completion of quality and safety testing before use as well as transportation of the cells between the sites of collection, processing and clinical administration. Finally, the ability to preserve cells used therapeutically facilitates the development of a manufacturing paradigm for stem cell based therapies. The ability to preserve the cells after production of the therapy facilitates coordination of therapy with a patient care regime and reduces staffing requirements of clinical cell production facilities.
DEAR FRIEND
WE KNOW THAT NOW A DAYS STEM CELLS ARE VERY USEFUL. SO FOR THIS PURPOSE OF PRESERVATION SAMPLES OF STEM CELLS ARE COLLECTED FROM CORD BLOOD OR FROM RED BONE MARROW OR EMBRYO AND ARE KEPT IN SMALL STERILE VIALS.
THESE VIALS ARE KEPT IN LIQUID NITROGEN AT -135 DEGREE C. TO -190 DEGREE C.
MAY THIS ANSWER HELP YOU !
