Focal dermal hypoplasia popular during the second half of the 20th century. Focal dermal hypoplasia Focal dermal hypoplasia (also known as "Goltz syndrome") is a form of ectodermal dysplasia. It is a multisystem disorder characterized primarily by skin manifestations to the atrophic and hypoplastic areas of skin which are present at birth. These defects manifest as yellow-pink bumps on the skin and pigmentation changes. The disorder is also associated with shortness of stature and some evidence suggests that it can cause epilepsy. Focal dermal hypoplasia has been associated with PORCN gene mutations on the X chromosome. 90% of the individuals who are affected
Dermal fibroblast by researchers at the Harvard Stem Cell Institute, dermal cell "human keratinocyte [stem cells] could be propagated in vitro when culture on fibroblast feeder cells." In addition to improving the culture and proliferation of stem cells, dermal fibroblasts can also become stem cells. Although dermal cells demonstrate less plasticity than other fibroblast cell types, researchers can still turn these cells into induced pluripotent cells (IPCs). As noted by researchers within the Harvard Stem Cell Institute, researchers obtained fibroblasts from a mouse with sickle cell anemia and, using a virus, "reprogrammed these cells into pluripotent [stem cells], corrected the genetic deficiency
