Stem cells are the mother cells that are responsible for developing an entire human body from a tiny two celled embryo; due to their unlimited divisions and strong power to differentiate into all the cells of different lineage. This power of stem cells has been harnessed by the technology to isolate them outside the human body, concentrate in the clean environment and implant back.
Thus, stem cells treatment involves administration of concentrated cells in the targeted area, wherein they can colonize in the damaged area, adapt the properties of resident stem cells and initiate some of the lost functions that have been compromised by the disease or injury.
After years of research, it has been believed that it is better to alter the microenvironment with the application of stem cells instead of suppressing the immune system. Mesenchymal stem cells are known to have angiogenic, transdifferentiation and homing properties, which are useful for forming new blood vessels, differentiating into required targeted cells and creation of microenvironment for the faster secretion of immune cells.
