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
Catholic theology of the body the image of God. These questions, addressed by the ancient Church, are relevant to a modern theology of the body, because they relate to concerns and definitions on the beginning and nature of human life. Clement of Alexandria (140?-220) viewed the body as the inferior partner in the body-soul relationship. The body tends to be sinful.
