A 3D molecular atlas of the chick embryonic heart

ABSTRACT: We performed a detailed analysis of gene expression in the 2-day (HH12) embryonic chick heart. RNA-seq of 13 microdissected heart regions reveals regionalised expression of about 15,000 genes (Dataset 1). Of these, 131 genes that are differentially expressed (FPKM ≥20, fold change ≥1.1-4.0) within a region compared to the other 12 regions were studied by in situ hybridisation (bold text in Dataset 1) and used to generate a 3D molecular map of the heart at this stage of development.

We present a detailed analysis of gene expression in the 2-day (HH12) embryonic chick heart. RNA-seq of 13 micro-dissected regions reveals regionalised expression of 15,570 genes. Of these, 132 were studied by in situ hybridisation and a subset (38 genes) was mapped by Optical Projection Tomography or serial sectioning to build a detailed 3-dimensional atlas of expression. We display this with a novel interactive 3-D viewer and as stacks of sections, revealing the boundaries of expression domain ...[more]

Project description:Eight different types of sample (three samples each) were used in this study of cardiac cell migration in the tunicate Ciona intestinalis. The B7.5 lineage cells were isolated by Fluorescent Activated Cell Sorting (FACS) at the tailbud stage, when the cardiac precursors (anterior B7.5 lineage cells) are migrating into the trunk, while their sister cells (posterior 7.5 lineage cells) remain in the tail, where they form muscle cells. Cells were sorted at the late gastrula stage, prior to migration induction and after manipulation of the FGF-MAPK-Ets signaling pathway (targeted expression of dominant negative FGF receptor and Ets:VP16 fusion protein, targeted expression was achieved using the Mesp cis-regulatory DNA), FoxF function (a direct target of FGF-MAPK-Ets signaling, required primarily for cell migration) by targeted expression of FoxF:VP16 (constitutive activator) or FoxF:WRPW (constitutive repressor, dominant negative), Mesp function (over-expression of Mesp:VP16 inhibits primarily cell migration). Finally, the "whole embryo" samples were collected from dissociated whole tailbud embryos, without FACS. in summary the eight conditions are: "wt (files LC-wt-1,-2,-3)": wild_type B7.5 lineage cells, expressing GFP, sorted at the tailbud stage "Ets:VP16 (files LC-EV-1,-2,-3)": B7.5 lineage cells, expressing GFP and Ets:VP16, sorted at the tailbud stage "DnFGFR (files LC-dnFGFR-1,-2,-3)": B7.5 lineage cells, expressing GFP and dominant-negative FGF receptor, sorted at the tailbud stage. "FoxF:VP16 (files LC-FV-1,-2,-3)": B7.5 lineage cells, expressing GFP and FoxF:VP16, sorted at the tailbud stage. "FoxF:WRPW (files LC-FW-1,-2,-3)": B7.5 lineage cells, expressing GFP and FoxF:WRPW, sorted at the tailbud stage". "Mesp:VP16 (files LC-MV-1,-2,-3)": B7.5 lineage cells, expressing GFP and Mesp:VP16, sorted at the tailbud stage. "Late Gastrula (files LC-LG-1,-2,-3)": wild_type B7.5 lineage cells, expressing GFP, sorted at the late gastrula stage "whole embryo (files LC-whole-1,-2,-3": whole embryos, dissociated at the tailbud stage, not sorted.
