About Stem Cells

There are stem cells in practically every tissue of your body, but stem cells are not all the same.  There are different stem cells that we can find in various tissue sources that possess different characteristics.  A stem cell is defined as a cell that can transform or differentiate into a particular cell type, like a skin cell or muscle cell.  Various safety and ethical issues drove a lot of research into different stem cell sources and scientists quickly realized the potential of using stem cells from one’s own body.  This is called “autologous use” of adult stem cells.

(B) Differentiation of hAdMSCs into osteoblasts as evaluated by Alizarin red S staining. (C) Chondrogenic potential of hAdMSCs as shown by toluidine blue O staining. (D) Differentiated myocytes were detected by immunostaining with myosin antibody (E). The hAdMSCs showed neurogenic differentiation by immunostaining with MAP2, (F) neuron specific enolase, (G) TUJ1, and (H) GFAP antibodies. hAdMSC, human adipose tissue-derived mesenchymal stem cells.
