Stem Cell Therapy
Stem Cell Therapy: Stem cells are undifferentiated biological cells that can differentiate into specialized cells, which can divide to produce more stem cells. They are commonly found multicellular organisms, Normally, in adults stem cells act as repair system for the body, replenishing adult tissues. The main autologous stem cells in humans are bone marrow, adipose tissue (lipid) and blood. Stem cells have the property of self-renewal (they can undergo numerous cycles of division) and potency (Ability to differentiate into different types of cells). Stem cells can now be artificially grown after being obtained from either the amnion or the umbilical cord blood. These have the ability to continuously divide & multiply, which allows us to substitute any damaged or destroyed cells. Stem cell therapy is used to treat or prevent a disease or condition. This revolutionary form of treatment enables us to treat many medical conditions such as:
- Cancers such as Leukemias and lymphomas – by bone marrow transplant.
- Neurodegenerative diseases such as Parkinson’s, Alzheimer’s, sclerosis etc. – It has been researched that stem cells can used to migrate within the brain and function to maintain neuronal system.
- Brain & Spinal cord Injuries – Stroke, brain injury etc. – It has sown that stem cells can replace damaged or dead brain cells.
- Heart ailments secondary to cardiac injury – Stem cell therapy can be used for treatment of myocardial infarction by some mechanisms such as generation of heart muscle cells, stimulation of growth of new blood cells, secretion of growth factors and a few other mechanisms.
- Baldness by replacing hair follicles – It helps after activating the existing the stem cells on the scalp. This signaling gives chemical signals to follicle cells, which in turn regenerates and forms healthy hair.
- Diabetes – Diabetic patients loose the function of insulinproducing beta cells. Stem cells have been used for replacing damaged beta cells of pancreas.
- Deafness – Stem cells act by re-growing of cochlea hair cells.
- Orthopedics – Stem cells have proved revolutionary in increased growth of cartilage and meniscus.
- Wound healing – Wounded tissue is commonly replaced by scar tissue. Stem cells stimulate the growth of human tissues and can be used to replace wounded tissue to normal tissue.
- Blindness – Stem cells have been used to treat blindness by replacing the damaged corneal cells.
- Infertility – The stem cells can also be used to differentiate into germ cells using mitotic division.
- HIV/AIDS – Studies and trails have been done to treat infected patients with modified gene expression. The main aim is to create a disease resistant immune system through transplantation of autologous, gene-modified hematopoietic stem cells.
- And various other applications.
