Pluripotent Stem Cells
► The outer blastocyst cell layer forms the placenta that provides nourishment to the fetus.
► Pluripotent embryonic stem cells ( ES cells) are formed from the inner group of stem cells and help in formation of the embryo's tissues.
► Pluripotent cells are more versatile than an adult stem cell and can produce many different cell types.
► These cells are easier for controlling growth and differentiation than adult stem cells.
► Pluripotent stem cells are more abundant than adult stem cells and therefore significantly easier to isolate.
► Research studies done on animal ES cell (Pluripotent embryonic stem cells) experiments can be used to understand Human stem cells.
Human pluripotent stem cells can be produced from:
- Isolation of ES cells from blastocyst during in vitro fertilization.
- ES cells can be extracted from eggs or sperms of aborted or miscarried fetus.
- Production of tailor made ES cells from patients own differentiated cells by using cloning techniques.
