Answer: One of the benefits of cord tissue-derived stem cells is that they are always available for use without delay. Directly after expansion, the cells are cryogenically preserved in a protective solution at -150F, similarly to how eggs or sperm are stored for future use in IVF. Once ready for use, the cells are carefully brought to the appropriate temperature and immediately tested for cell count and viability to ensure they meet all necessary quality assurance (QA) standards. Any cells which do not meet the optimum standards (viability numbers) are not used in treatments.
