The current and potential therapeutic uses of stem cells
Introduction:
Medical researchers believe that stem cells therapy has the potential to cure human diseases and alleviate suffering. A number of stem cell treatments exist, but often they are too expensive for daily use, with the notable exception of bone marrow transplant. Although it is widely accepted that stem cells research can improve physical impairments, various social, scientific and technological uncertainties are likely to hinder any further progress.
Technology of stem cells therapy:
Stem cells are primal cells found in all multicellular organisms. They have the ability to renew themselves through the process of mitosis, and can differentiate into a board range of different specialized cell types. The three major mammalian stem cells are embryonic stem cells, derived from blastocysts, adult stem cells, which are found in adult tissues, and cord blood stem cells, which are found in the umbilical cord. These stem cells can undergo mitosis under laboratory conditions and transformed into specialized cells. Stem cells are said to have unlimited potency, indicating the capability to differentiate into any mature cell type.
