Figure 9. Tbx2, Mtg8, Mtg16, and Mtgr1 function is required for ectopic and endogenous beta cell development at Stage 32. Tbx2 or Mtg morpholinos (40 ng each) were injected alone or with Ngn3-GR mRNA (1,800 pg) and activated with Dex for 4 h at Stage 12 and the embryos grown to Stage 32 and analyzed for insulin expression. (a) Injection of Mtg8 morpholino blocked ectopic insulin expression by Ngn3-GR (n = 20/27). Mtg8 morpholino alone inhibited endogenous insulin expression (n = 40/77). (e) Mtg16 morpholino blocked ectopic insulin expression by Ngn3-GR (n = 16/20). Mtg16 morpholino alone inhibited endogenous insulin expression (n = 27/52). (i) Mtgr1 morpholino blocked ectopic insulin expression by Ngn3-GR (n = 28/28). Mtgr1 morpholino alone did not inhibit endogenous insulin expression (n = 46/59). (m) Tbx2 morpholino blocked ectopic insulin expression by Ngn3-GR (n = 27/27). Tbx2 morpholino alone inhibited endogenous insulin expression (n = 20/37).
