A fibroblast is a type of cell that synthesizes the extracellular matrix and collagen, the structural framework (stroma) for animal tissues, and plays a critical role in wound healing.Fibroblasts are the most common cells of connective tissue in animals.ibroblasts and fibrocytes are two states of the same cells, the former being the activated state, the latter the less active state, concerned with maintenance and tissue metabolism.
Adorable animal families that will make you aww. Myocardial fibrosis is a condition that involves the impairment of the heart's muscle cells called myocytes. It belongs to a class of diseases collectively known as fibrosis, which denotes hardening or scarring of tissue.ormally, myocytes form lines of cells in the heart. In myocardial fibrosis, myocytes are replaced by tissue that is unable to contract. This happens when fibroblasts, which produce collagen to enable wound healing, provide excessive amounts of the protein. This results in a case of abnormal scarring, or fibrosis.
