Fig. 7. Fgf proteins exert different effects on cell proliferation in the
developing palate. (A-C) Fgf10 inhibits cell proliferation (B), while Fgf2
stimulates cell proliferation (C) in E13.5 anterior palatal tissue when
compared with tissue treated with BSA (A). (D-F) Cell proliferation levels are
similar in the posterior palatal tissue implanted with either BSA bead (D) or
Fgf10 bead (E). However, cell proliferation level is significantly increased
in the posterior palatal tissue implanted with Fgf2 bead (F). b, bead.
