myofibroblast
This term is a technical biological descriptor used almost exclusively in medical, histological, and pathological contexts. It describes a hybrid cell type that bridges the gap between structural support and active contraction, making it central to the study of fibrosis and wound healing.
In clinical discussions, the term often carries a negative connotation when associated with chronic conditions, as the overactivity of these cells leads to the formation of hypertrophic scars or organ fibrosis, where healthy tissue is replaced by rigid connective tissue.
Ý nghĩa
A specialized cell that possesses characteristics of both a fibroblast and a smooth muscle cell, primarily responsible for wound contraction and the deposition of extracellular matrix during tissue repair.
The presence of myofibroblasts is a hallmark of the granulation tissue formed during the healing process.
