Our body is made up of more than 200 different types of cells, each with a distinct and specialised function. These ‘working cells’ perform different functions in the body. Stem Cells are different from the ‘working cells’ of our body. These are the special cells or master cells with the remarkable potential to develop into many different types of cells in body. Stem cells have the ability to make different ‘working cells’ in our bodies. They are the building blocks of body, all different parts of the body like blood, skin, bones etc. are formed out of stem cells.
