Scar dressings are commonly used in managing burn and hypertrophic scars, although supporting evidence is lacking. Care providers commonly report improvements, however, and pressure therapy has been effective in treating ear keloids. The general acceptance of the treatment as effective may prevent it from being further studied in clinical trials. A long-term course of corticosteroid injections into the scar may help flatten and soften the appearance of keloid or hypertrophic scars. Topical steroids are ineffective. However, clobetasol propionate can be used as an alternative treatment for keloid scars. Scar revision is a process of cutting the scar tissue out. After the
Neural tissue engineering lack of blood flow to certain tissues. Traumatic brain injury is caused by external forces impacting the cranium or the spinal cord. Problems with CNS development results in abnormal tissue growth during development, thus decreasing the function of the CNS. One method to treat CNS injury involves culturing stem cells "in vitro" and implanting the non-directed stem cells into the brain injury site. Implanting stem cells directly into the injury site prevents glial scar formation and promotes neurogenesis originating from the patient, but also runs the risk of tumor development, inflammation, and migration of the stem cells out of the
