Stem Cells: Unspecialised cells - can develop into different types of cells
Differentiation: When Stem cell becomes specialised for a job - e.g. Bone Marrow Stem Cells turn into White and Red Blood Cells - replaces dead or damaged cells throughout body
Self-Renewal: Maintains Stem Cell pool
Potency: How many tyoes of specialised cells can a Stem Cell make
Embryonic Stem Cells: Early embryo -can be put into any cell (used to help in renewal or treat disease) - Cells from Blastocyst form particular organs based off of Stem cells around them (Cell Signalling)
Pluripotent: Can form any specialised cell
Multipotent: Can only form some specialised cells
Ethical Issues: Potential for life, Sancity of Life (Save everyone - the many outway the few)
