Figure 2. Expression patterns of genes regulated during palate development in vivo (A,B,C,D,E,F) and in organ culture (G,H,I,J,K,L), assessed by RT-PCR. (A,G) tgfß₃, fgfr1; (B,H) fgfr2IIIb; (C,I) twist, snail; (D,J) E-cadherin, keratin 5; (E,K) dsg1; (F,L) vimentin. Error bars represent the standard error of the means (SEM); n = 3. Asterisks indicate significant differences between 2 time-points (P < 0.05).
