Stem cells

Another important milestone in the medicine in this era is the identification of stem cells, in general stem cells are cells which are present in almost all organisms from yeast to human and it may be absent in some unicellular organisms but it is seen in all multi cellular organisms. The main advantage of stem cells is that it can renew itself through the mitotic cell division and it can also differentiate itself into a diverse and specialized range of cells, and these stem cells can be grown and transformed into specialized cells with characteristics consistent with cells of various tissues such as muscles or nerves , they are widely used in medical field and this cells can be transformed by means of cell therapies, The main purpose of these cells is their ability to regenerate themselves over the entire lifetime, so when we change our all normal cells into stem cells in our body , no cell can be damaged and if gets damaged it can regenerate itself so there is no need of medicine, so stem cells have a remarkable important in medicine.
