Stem Cell - Research Paper Example The paper tells that cells with the ability to divide constantly as well as distinguish and extend into numerous cells and tissues of various kinds are known as stem cells. They are ‘blank’ cells as they do not display any precise physiological predisposition. With the onset of appropriate conditions, in vitro or in vivo, stem cells develop into focused tissues and organs as they are self-sufficient and replicate by the process of cell division, indicating that stem cells are biological entities prevalent in multicellular organisms. As stem cells possess distinctive eminence and research embraces an immense assurance for the management and cure of critical and unbearable ailments like Alzheimer's disease, Parkinson's disease, cancer, diabetes and neurological as well as metabolic disorders, diseases related to hear, stroke, bone condition, osteoarthritis, rheumatoid arthritis, as well as conditions like multiple sclerosis. Stem cells could also be grown to become new tis sue for use in transplant medicine. Research is being carried out across the world to decipher the underlying genetic and biochemical facts triggering stem cell delineation to new cells capable of repairing distorted tissues and organs. Stem cells pave the way towards understanding of various diseases and syndromes. Stem cells are promising resources to test the drugs and agents. Stem cells are pluripotent, i.e. capable of replicating into similar kind of cells or they are capable of specializing into any other specific tissue. There are various categories of stem cells: Embryonic stem cells- They are procured from the interior cells of the blastocyst. Fetal stem cells- They are procured from the germ line tissues of aborted fetus. Umbilical cord stem cells- Blood of the umbilical cord encompasses stem cells similar to the cells present in the bone marrow. Placenta derivative stem cells- Source of enormous stem cells. Adult stem cells- Numerous adult tissues also possess stem cells. These stem cells are harvested to rectify ailments or cloning tissues, organs, animals or humans or they may be harvested for gene-line engineering. The gene-line engineering aims to function towards disease resistance and functional improvement. Induced pluripotent cells- Through nuclear programming scientists have transformed adult cells into stem cells. Nuclear programming alters the genes to behave like embryonic stem cells and thereby avert immune rejection, although adverse effects could not be documented so far. Amniotic fluid stem cells- Researchers have documented the presence of stem cells in amniotic fluid (Where do stem cells come from?; Stem cells: What they are and what they do?). Scientists are using stem cell lines derived from the single stem cell. They are devoid of genetic defects and could be stored as well as used for various research purposes to get regenerative medicines for damaged or degenerated tissues through gene manipulation technique which aids in gene rating
