Amniotic Fluid Stem Cells: A New Era in Regenerative Medicine.

Regenerative medicine has become an emerging field which focuses on repair, replacement or regeneration of cells, tissues and the entire organs. The regeneration may occur in patient's own body by using their system as a bioreactor, e.g., cell therapy that involves transplantation of stem cells capable of proliferating, differentiating and replacing damaged host cells. As the field of regenerative medicine advances, and sources of stem cells has been intensified. Though embryonic and adult tissues can be used for isolation of pluripotent stem cells, the amniotic fluid (AF) has been proposed as an alternative source of stem cells for tissue regeneration. AF cells could be banked and used for either allogeneic or autologous transplantation.
