FIG. 2. GATA-4/5/6 transcription is maintained and enhanced in both the mesoderm and the endoderm of RA-treated embryos. (a) Sagittal
sections taken from embryos analyzed first by whole-mount in situ hybridization for Nkx2.5 or GATA-4/5/6 (top to bottom). Embryos are
oriented as in Fig. 1; the cement gland is visible as brown tissue (adjacent to the Nk in the upper left image). Sections from control
DMSO-treated embryos are shown on the left; samples from RA-treated embryos are on the right. The position of the folded heart (ht) is
indicated on the left. The myocardial (arrowhead) and associated endoderm layer (En), both of which are positive for GATA-4/5/6, are
indicated on the right. (b) Cross section of a similarly treated embryo analyzed for GATA-4 transcripts. Dorsal is to the top. The endocardial
(EC) layer is indicated for both control (top) and RA-treated (lower) samples. Image published in: Jiang Y et al. (1999) Copyright © 1999. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View |
