From where are fetal stem cells typically harvested?

Fetal stem cells are typically harvested from the developing central nervous system (CNS). During embryonic development, the CNS is a rich source of pluripotent stem cells, which have the ability to differentiate into various cell types. These stem cells are essential for growth and development and hold great promise for regenerative medicine due to their potential to regenerate damaged tissues.

In contrast, adult tissues, bone marrow, and peripheral blood primarily contain adult stem cells, which are generally multipotent and have a more limited differentiation potential compared to the pluripotent fetal stem cells found in the developing CNS. Understanding the source of these stem cells is crucial for advancements in treatments for various diseases and injuries.
