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.
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.
Stem-cell therapy for the treatment of myocardial infarction usually makes use of autologous bone marrow stem cells, but other types of adult stem cells may be used, such as adipose-derived stem cells. [54] Possible mechanisms of recovery include: [33] Generation of heart muscle cells, Stimulating growth of new blood vessels to repopulate ...
Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
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 ...
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.
Acute tubular necrosis (ATN) in the kidney is a case in which cells heal completely by regeneration. ATN occurs when the epithelial cells that line the kidney are destroyed by either a lack of oxygen (such as in hypovolemic shock, when blood supply to the kidneys is dramatically reduced), or by toxins (such as some antibiotics, heavy metals or carbon tetrachloride).
