A stem cell is a type of cell that has the ability to differentiate into different types of cells in the body. They may be utilised to replace cells and tissues that have been injured or lost as a result of disease in the future. Stem cell therapy has become a very promising and advanced scientific study area in recent years. The advancement of therapy procedures has sparked high hopes. To carry out its specific responsibilities, a stem cell is demanding and requires exact circumstances. Proliferation as an undifferentiated stem cell, differentiation into more mature cell types, migration through tissue to its final destination, and functional integration into the cellular network are all part of this process. Both internal and extrinsic factors have a role in all of these processes.
