Dermal fibroblast fibroblast and a corneal fibroblasts are placed in the same concentrations of fibroblast growth factor, dermal fibroblast will not differentiate or change. As noted by Dr. J. Lewis and Dr. A. Johnson authors of "Microbiology of the Cell", "fibroblasts from the skin are different" and behave differently from other fibroblast cells to identical chemical stimuli. Furthermore, dermal fibroblasts are less likely to replicate in either "in vivo" and "in vitro" environments than are other fibroblast types. Dermal fibroblasts require far higher concentrations of fibroblast growth factor (FGF) in order to undergo cell replication. Dermal fibroblasts are responsible for creating the
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
