Possible Stem Cell Sources and Types for Covid‐19 Patients
Stem cells are unspecialized cells in the body that have the potential to make more stem cells as well as differentiate into specialized cells of the body if appropriate signals are given in vitro or in vivo. Embryonic stem cells (ESCs) can be isolated from the inner cell mass of 5–8 days old embryos and possess high regenerative potential. However, the clinical use of ESCs is restricted due to a number of religious, ethical, and legal controversies. Adult stem cells can be isolated from neonatal sources (such as cord blood, cord tissue, placenta, and menstrual blood) as well as from adult tissues (such as bone marrow, adipose tissue, dental pulp, and peripheral blood) are used for these purposes.
