Human amniotic fluid cells have been used traditionally as a diagnostic tool for genetic anomalies. More recently it has been recognized that amniotic

fluid contains populations of stem cells. Mesenchymal stem cells (AFMSC) were first to be described. These cells are able to differentiate towards

mesodermal lineages. More recently cells with broader potential, defined as amniotic fluid stem cells (AFSC), were also isolated. They have

intermediate characteristics between embryonic and adult stem cells and are able to differentiate into lineages representative of all three germ layers

but unlike ES cells they do not form tumours in vivo. Furthermore, AFSC have been reverted to functional pluripotency in a transgene-free approach

using an epigenetics modifier. These characteristics, together with absence of ethical issues concerning their employment, have made stem cells from

amniotic fluid a promising candidate for cell therapy and tissue engineering.
