What are Stem Cells?
Stem cells are progenitor cells in your body that have the potential to multiply and differentiate into specific cell types in order to replenish old and diseased cells. They are present in the body as part of the repair mechanism. Scientists have now found means of extracting, growing and manipulating them in a lab so that they multiply and differentiate into desired cell types. These are used in stem cell therapy or regenerative medicine to replace, repair and heal injured, dysfunctional or diseased tissues such as blood, muscle or nerves.
Stem cells are also present in hair follicles and may be stimulated to revive shrunken hair follicles. A good source of stem cells is fat from your own body, which is collected by liposuction. Stem cells are then extracted from the fat and either injected directly into the concerned areas or administered intravenously to regenerate hair follicles and improve the density of hair.
