Stem Cell Therapy For Treating A Range Of Deadly Medical Conditions And Diseases
Stem cell therapy for autism
The stem cell therapy procedure uses stem cells for treating or preventing any particular medical condition. Stem cells are found only in the multi-cellular organisms, including humans. The undifferentiated mass of stem cells later grows and differentiates into the specialized cells through a cell division and growth process that is called mitosis.
Uses of stem cell therapy
Stem cells are not just used for treating cancer; they are used for treating other medical conditions as well.
The most widely practiced form of stem cell therapy is the bone marrow transplant, where the stem cells of the bone marrow of a donor are transplanted into the body of a cancer patient who is suffering from conditions like lymphoma and leukemia. During the cancer therapy, almost all of the growing cells of the patient’s body are destroyed by cytotoxic agents that are used during the therapy. The donor donates his/her healthy bone marrow cells that can replace the killed or destroyed cells of the patient’s body (cells that the patient loses during chemotherapy). These healthy and transplanted stem cells of the bone marrow also produce a desired immune response that can kill the cancerous cells.
Stem cells can also cure brain disorders and diseases related to brain degeneration. Stem cell therapy is being researched upon so that diseases like Alzheimer’s disease, Parkinson’s and Multiple sclerosis can be treated fully. Stem cell therapy for autism has been found to provide for neuroprotection and can also help in behavioral recovery.
Spinal Cord and Brain Injury
A traumatic and bigger brain injury and stroke can cause the death of cells. The body loses oligodendrocytes (non-neuronal cells) and neurons in these conditions. Stem cells are also being researched upon to offer cure and therapy in these conditions.
Stem cell therapy for heart conditions helps in generation of the heart muscle cells, secretion of the growth factors, stimulation of the growth of new and healthy blood vessels and other kinds of assistance. The stem cell therapeutic procedure uses the autologous bone marrow stem cells and the “adipose-derived” stem cells.
Blood Cell Formation
The stem cell therapy provides for ex-vivo “red blood cell formation” and uses the hematopoietic cells (HSC) for the purpose. The HSCs are the precursors of the red blood cells. A laboratory environment that mimics the bone-marrow environment is created and a growth factor called “erythropoietin” is also added so that cells can grow fully.
Scientists believe that the stem cell therapy can be used for growing live teeth in human patients, and experiments on mice have been successful in this regard.
The patient’s stem cells are taken and are turned in the form of a tooth bud in the lab. The bud is implanted within the gums, and it gives rise to a new tooth. The tooth grows with a time period of 3 weeks fully. It gets fused with the jaw bone and also releases chemicals that provide for blood vessel and neural connections.
Vision Impairment and Blindness
The cells of the cornea have been successfully transplanted for restoring the vision in damaged eyes. The stem cells can stimulate repair and restore the vision fully.
Stem cells have also been found useful in treating diabetes. The scientists coax the embryonic cells so that they can turn into the beta cells (beta cells are found in the pancreas and produce insulin). According to the theory, if these beta cells can be transplanted in a successful manner, the malfunctioning pancreas will have their functionality restored.
Apart from these, stem cells are also being probed upon for their effectiveness in treating other medical conditions and diseases like HIV, infertility and wound healing. Stem cell therapy is one of the biggest medical advancement techniques and holds a lot of merits to cure a range of deadly diseases fully.
