Detailed explanation-1: -The given statement is false. The stem cells are regarded as the undifferentiated mother cells that act as the raw material for the living organisms. The human stem cells function as the principal cells that need to differentiate into special cells.

Detailed explanation-2: -One of the oldest methods for stem cell differentiation is the generation of embryoid bodies (EBs). Generally, when stem cells are cultured without an adherent surface, feeder cells, or a complex matrix, the cells aggregate. These aggregated cells spontaneously differentiate. An EB contains all three germ layers.

Detailed explanation-3: -Stem cells are unspecialized cells of the human body. They are able to differentiate into any cell of an organism and have the ability of self-renewal.

Detailed explanation-4: -These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.

Detailed explanation-5: -Stem cell markers are genes and their protein products used by scientists to isolate and identify stem cells. Besides, stem cells can also be identified by functional assays which are considered the gold standard for the identification and therapeutic purposes.
