REGENERATIVE MEDICINE :
Stem cell therapy is an important component of regenerative medicine, that refers to therapy whereby stem cells or progenitor cells are used to replace, repair and regenerate damaged cells or diseased cells.
Regenerative medicine is a broadly defined term that refer’s to innovative medical therapies, that enable the body to repair, replace, restore and regenerate damaged or diseased cells, tissues and organs. It includes making the use of advanced medical devices and bio – materials to achieve this purpose. These treatments include cell therapies, bio – engineered tissue products, and gene therapies. Regenerative techniques, such as Bone marrow or organ transplantation have been used for many year’s. However in the late 1990’s, scientist’s were able to isolate and grow cells from embryonic tissue called Pluripotent cells, that could differentiate into almost any type of cell from the 200 types of cells in the human body. Over the next decade, scientist’s were able to genetically engineer such differentiation in the adult stem cells also. This was a revolutionary break through in the field of Medicine. A few year’s back, scientist’s have succeeded in discovering new technologies that enable the editing and transfer of genetic material that is a new hope for the treatment of hereditary disorder’s and other chronic condition’s.
Stem cell therapy has potential to treat health problem’s, allieviate symptom’s and also slow down the progression of any disease. Autologous stem cells or tissues are taken from one’s own body, and then injected into the site of injury or disease, so that the cells can transform into the type of cells that are required for the healing of that particular disease or repair of the injury.
The objective is to nurture and enhance the natural healing mechanism in the body, as well as to improve the body immunity. There are 3 main types of stem cells they are Totipotent, Pluripotent and Multipotent stem cells. They can be obtained from any part of the human body such as the liver, skin, bone marrow, umbilical cord blood, adipose tissue, amniotic fluid.
