The surviving epithelial cells, however, undergo migration, dedifferentiation, proliferation, and redifferentiation to replenish the epithelial lining of the proximal tubule after injury. Recently, the presence and participation of kidney stem cells in the tubular regeneration has been shown.
Marrow-nucleated cells are used every day in regenerative orthopedics. The knee microfracture surgery technique relies on the release of these cells into a cartilage lesion to initiate fibrocartilage repair in osteochondral defects. [13] In addition, this cell population has also been shown to assist in the repair of non-union fractures. [14]
In particular, mesenchymal stem cells have been shown in animal models to regenerate cartilage. Recently, there has been a published case report of decrease in knee pain in a single individual using autologous mesenchymal stem cells. An advantage to this approach is that a person's own stem cells are used, avoiding transmission of genetic diseases.
Regenerative medicine also includes the possibility of growing tissues and organs in the laboratory and implanting them when the body cannot heal itself. When the cell source for a regenerated organ is derived from the patient's own tissue or cells, [3] the challenge of organ transplant rejection via immunological mismatch is circumvented.
Stem cells enable surgeons to grow replacement cartilage, which gives the new tissue greater growth potential. [ 11 ] [ 12 ] While there are few long-term studies as of 2018, a history of knee problems [ 13 ] and body weight are factors for how well the procedure will work.
One of the best ways to keep your mind working well and prevent dementia and cognitive decline is to eat a diet full of brain foods. The most common type of dementia, Alzheimer’s disease ...
Neuroregeneration is the regrowth or repair of nervous tissues, cells or cell products. Neuroregenerative mechanisms may include generation of new neurons , glia , axons , myelin , or synapses . Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms involved ...
Higher levels of omega-6 fatty acids often found in ultraprocessed foods may interfere with the immune system’s fight against cancer cells, a new study says.
