(A-C) 4-somite stage embryos injected with ngn1 RNA and stained for islet-1 expression by in situ hybridization. (A) Lateral view of an injected embryo showing ectopic islet-1-positive cells in the ectoderm adjacent to the neural plate. (B,C) Dorsal views reveal a reduction in the number of islet-1-positive cells within the neural plate following misexpression of ngn1 (asterisks). (D,E,F) 3-somite stage embryos injected with neurogenin1 RNA and stained for the expression of deltaA (D), deltaD (E) and her4 (F). Transcription is activated within the neural plate (asterisks). |
