library_construction_protocol: Collected embryos were embedded in Tissue freezing medium and stored at -80°C until sectioning. The whole embryo tissue was serially cryo-sectioned along craniocaudal axis at 10μm, and about 1000 sections were harvested. Considering the morphology and uniform sampling, 10 sections from a male embryo and 4 sections from a female embryo were selected for spatial transcriptomic analysis by 10x Genomics Visium platform. These sections were then used for spatial transcriptomic analysis by 10x GenomicsVisium platform according to manufacturer's construction.
