Endogenous collagen synthesis is sufficient for DDR2 phosphorylation. HSC-T6 stellate cells were cultured for 48 hours in the presence of the proline analogue cis-OH-Pro to reduce collagen synthesis. (a) Levels of type I collagen were analyzed with a Western blot of cell lysates using a polyclonal Ab. (b) Cell lysates were immunoprecipitated with the polyclonal anti-DDR2 Ab R2-JM, followed by analysis of Western blotting with an antiphosphotyrosine Ab (4G10) or anti-DDR2 (R2-JM).
