Expression pattern of SCL, GATA-2, and GATA-3 in AGM shown by in situ hybridization. Embryos were injected with either (A-C) LacZ (control) or (D-F) truncated c-met mRNA into 2 ventral-vegetable blastomeres. (A,D) SCL expression at stage 30/31. (B,E) GATA-2 expression at stage 30/31. (C,F) GATA-3 expression at stage 33. Yellow arrowheads indicate expression of these genes in DLP.
