Embryonic stem cells (ESC)

Tissue specific progenitor stem cell(TSPSC)

Mesenchymal stem cell(MSC)

Induced pluripotent stem cells(IPSC)

Embryonic stem cells are obtained from the inner cell mass of the blastocyst a mainly hollow ball of cell that in the human forms 3 – 5 days after an egg cell is fertilized by a sperm. The cell inside the inner cell mass will give rise to the more specialized cells that give to the entire body all of our tissues and organs

Tissue specific stem cells specialized than ESC these stem cells generate different types for the tissue or organ in which they live these cells are difficult to find in human body

Mesenchymal Stem cells are isolated from Stroma the connective tissue that surrounds other tissues and organs these cells are present in fat and cord blood not all MSC are the same their character depends on where in the body they come from and how they are isolated and grown

Induced pluripotent cells have been engineered in the lab by converting tissue specific cells such as skin cells into cells that behave like ESC. These tools are helpful for developing and testing new therapies and drugs
