fibroblast A cell that generates the protein COLLAGEN, a major component of connective tissue and the main structural material of the body. Nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. Cell culture and cell lines have assumed an important role in studying physiological, pathophysiological, and differentiation processes of specific cells. Fibroblasts produce tropocollagen, the forerunner of collagen, and ground substance. Fibroblasts from each of these niches exhibit distinctive differences when cultured separately.

Larger blood vessels travel through layers of loose connective tissue. 95 We assume only EGF secreted by fibroblasts that plays role in our keratinocyte–fibroblast wound healing system, hence fibroblasts solely act as EGF producer and make no or very slow movement. They can readily be cultured artificially. Fibroblast accumulation begins 3–5 days after injury and may last up to 14 days. Proliferation and transdifferentiation of lung stem cells (LSCs) could promote lung injury repair. However, while fibroblasts are known as “sentinel cells” in various nonneoplastic diseases, where they often regulate the composition and function of recruited leucocytes, they are hardly considered active participants in the inflammatory host response in tumors.
