Fig. 5. Effects of FGF9 on RCS cell morphology, cytoskeletal organization and FGFR3 localization. RCS cells were incubated with FGF9 and heparin for 10 minutes, 1 hour or 6 hours, fixed and double stained with antibodies to FGFR3 and anti-pTYR antibodies (A) or anti-vinculin antibodies (B) or phalloidin (C).
