Document Summary
Stem cells hold the promise to cure some incurable diseases like parkinson"s and. Prokaryotes do not have a membrane bound nucleus. Totipotent - early embryo (8 cell stage embryo) that can give rise to every type of cell in the body. Pluripotent - inner cell mass stem cells (5 days blastocyst) that can give rise to all different types of cells but the placental. Multipotent - blood stem cell, neuronal stem cell, can give rise to many cells but all specific to one tissue. Embryonic stem cell research lifted by obama fertilized embryos. Stem cells undergo a self-renewal process and divide or differentiate into a specific cell (multipotent) Expression of different genes leads to: cell differentiation. Different proteins, shape, receptor, and functions induced pluripotent stem cells - originally multipotent stem cells reversed though the process and can be used for more than pluripotent cells (avoids moral and religious complications)
