Detailed explanation-1: -Fibroblasts seem to be the least specialized cells in the connective-tissue family. They are dispersed in connective tissue throughout the body, where they secrete a nonrigid extracellular matrix that is rich in type I and/or type III collagen, as discussed in Chapter 19.

Detailed explanation-2: -Fibroblasts are the most common cell type of connective tissue. They produce both fibers and amorphous ground substance. Typically only the oval nuclei are visible. These cells are found associated with the fibers listed above.

Detailed explanation-3: -Fibroblasts are diverse mesenchymal cells that participate in tissue homeostasis and disease by producing complex extracellular matrix and creating signaling niches through biophysical and biochemical cues.

Detailed explanation-4: -A fibroblast is a cell that manufactures and maintains connective tissue, the structural framework that supports the organs of all animals. Fibroblasts secrete fibrous proteins and ground substance, which together form the extracellular matrix that is the basis of connective tissue.
