Collagen synthesis mediated by fibroblast activation (null)

Collagen synthesis via fibroblast stimulation describes the biological process in which fibroblasts, the primary mesenchymal cells responsible for producing extracellular matrix (ECM), are activated through signaling pathways such as TGF-β, JAK/STAT, PI3K, ERK, and AMPK to upregulate collagen gene transcription and subsequent collagen biosynthesis. This process is essential for tissue repair, wound healing, and maintaining skin integrity, but excessive activation can result in pathological fibrosis and contribute to tumor progression via the activity of cancer-associated fibroblasts (CAFs). Drugs can modulate these pathways to either promote or inhibit collagen deposition depending on therapeutic need.
