Detailed explanation-1: -Pluripotent differentiation potential enables PSCs to generate any desired cell type in vitro. PSC-derived cells such as neurons are particularly valuable for human due to the lack of alternative sources.

Detailed explanation-2: -In early pregnancy, the blastocyst stage continues for about 5 days before the embryo implants in the uterus, or womb. At this stage, stem cells begin to differentiate.

Detailed explanation-3: -Cellular differentiation is a fundamental process in which one cell type changes into one or more specialized cell types. Cellular differentiation starts at the beginning of embryonic development when a simple zygote begins to transform into a complex multicellular organism composed of various cell and tissue types.

Detailed explanation-4: -One example of a totipotent cell is a zygote, which is formed after a sperm fertilizes an egg. These cells can later develop either into any of the three germ layers or form a placenta. After approximately 4 days, the blastocyst’s inner cell mass becomes pluripotent. This structure is the source of pluripotent cells.
