Immunohistochemical analysis of paraffin-embedded human thyroid cancer tissue using Collagen III Antibody (HY-P83919, 1/1000). The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Function
Collagen III (COL3A1) is a fibrillar extracellular matrix collagen synthesized as pre-procollagen and enriched in extensible tissues, including skin, blood vessels, intestine, uterus, and lung[1]. Mechanistically, collagen III regulates collagen I fibrillogenesis, fibril diameter, extracellular matrix architecture, and tissue mechanical integrity[2][3]. In wound models, collagen III supports re-epithelialization and limits scar-associated collagen fiber alignment, while reduced collagen III increases myofibroblast differentiation and scar deposition[4][5]. In disease models, COL3A1 mutations or deficiency produce vascular and dermal fragility resembling vascular Ehlers-Danlos syndrome[6][7]. Compared with collagen I, collagen III functions less as a dominant tensile scaffold and more as a fibril-network modifier that controls matrix organization, mechanosensing, and repair quality[2][3][4]. For experimental applications, the collagen III N-propeptide cysteine-rich domain attenuates TGFβ signaling and suppresses fibroblast activation, supporting its use as a mechanistic inhibitor tool in fibrosis and scarring studies[8].
