BIOLOGY 3 Lecture Notes - Lecture 23: East Los Angeles College, Adult Stem Cell, Embryonic Stem Cell
Document Summary
They can divide and make identical copies of themselves over and over again (self-renewal) Remain unspecialized with no specific" function or become . Specialized (differentiated) w/ the potential to produce over 200 different types of cells in the body. Stem cell may differentiate or remain a stem cell. Pluripotent stem cells can differentiate into every cell type in body. Stem cells can be classified into three broad categories, based on their ability to differentiate. Totipotent stem cells are found only in early embryos. Each cell can form a complete organism (e. g. , identical twins). Pluripotent stem cells exist in the undifferentiated inner cell mass of the blastocyst and can form any of the over. 200 different cell types found in the body. Multipotent stem cells are derived from fetal tissue, cord blood and adult stem cells. Although their ability to differentiate is more limited than pluripotent stem cells, they already have a track record of success in cell-based therapies.
