Aaron Miller Biol 302 Dr. Reisman 10/18/11 Embryonic Stem Cells and Induced Pluripotent Stem Cells Embryonic stem cells (ESC’s) are actually a form of a pleuripotent stem cell. For a cell to be pleuripotent it must be able to give rise to all three germ layers as well as any adult or fetal cell type (Goldwaite). Embryonic stem cells are formed from the inner cell mass of a 4-5 day blastocyst which is an early stage of a human embryo. There are approximately 100 cells forming the blastocyst. To destroy the fertilized embryo one must take the inner cell mass and isolate it which is the cause of many ethical issues (Yu). Once the undifferentiated stem cells are cultured they become pleuripotent and differentiate into any of the three germ layers.

The future of embryonic stem cells looks very promising. Due to the pleuripotency of embryonic stem cells scientist believe they will be able to use ESC’s as a way to replace damaged and diseased organs (Yu).
