IGFR pathway is imporatnd for fibroblast activation.
IGF-1 stimulated Col1a1 and Col3a1 expression on stiff substrate. In contrast, IGF-1 treatment on soft substrate resulted in upregulation of ??SMA gene and protein expression, as well as Col1a1 and Col3a1 transcripts. In conclusion, IGF-1 stimulates differentiation of fibroblasts into a myofibroblast phenotype in a soft matrix environment and has a modest effect on ??SMA stress fiber organization in mouse lung fibroblasts.
IGF-1-induced collagen I expression was mediated by extracellular signal-regulated kinase 1/2 (ERK1/2)-dependent mechanism.
IGF-1 significantly increased levels of phospho-IGF-1R and ERK1/2 in a time-dependent manner in both MIFs and CCD-18Co cells.

Upon IGF-IR autophosphorylation the protein Shc is recruited to the receptor and becomes phosphorylated on tyrosine residues.36 Activated Shc then binds the adaptor Grb2 in an IRS-1-independent manner, leading to activation of the Ras-ERK pathway.36 This pathway of IGF-IR signaling has been most closely associated with cell differentiation and migration, but in some cases also can regulate the machinery of apoptosis, for example, in detachment-induced death, or anoikis, in fibroblasts.
