About Stem Cell
The belief that there exists an undifferentiated cell which can be programmed into another type of cell forms the basis of stem cell biology. Today, stem cells treatments have become a reality. The capability of stem cells to regenerate organs and tissues opens a wide spectrum of treatment possibilities for many diseases that were considered incurable.
There is an increasing interest in using stem cells in treatment of degenerative diseases such as Parkinson’s disease, Alzheimer´s disease, diabetes, osteoarthritis (OA), knee injury, osteoporosis, myocardial infarction, and multiple sclerosis for which there is no curative therapy.
Stem cells, characteristics and properties
Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division. Second, under certain physiologic conditions, stem cells can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues.
Nowadays, we know that stem cells are not only in the umbilical cord, but we can find them in all human body tissues. Stem cells are now isolated from adult specialized cells and there has been a continuing expansion in the number and type of stem cells under study.
