AP BIOLOGY

Detailed explanation-1: -A great variety of tissues (bone marrow, adipose tissue, and endometrium) are potentially sources of stem cells and among them the placenta is a transient organ from which it is possible to obtain mesenchymal stem cells[5]. The term placenta constitutes a very reliable rich source of fetal mesenchymal stem cells[6-9].

Detailed explanation-2: -Placental stem cells are cells sourced from the placenta, which is collected after delivery of full-term healthy babies.

Detailed explanation-3: -Since human cord blood, umbilical cord, placenta and amnion are normally discarded at birth, they provide an easily accessible alternative source of stem cells.

Detailed explanation-4: -The process involves freezing placentas in a way that allows them to later be defrosted and suffused with a compound that enables the extraction of viable stem cells. The method will make it possible for companies to gather, ship and store placentas in a central location.

Detailed explanation-5: -In addition to hematopoietic progenitors and HSCs, the placenta also enriches mesenchymal stem cells (MSCs). MSCs have a broad differentiation potential [203].
