library_construction_protocol: Hearts from E14.5 Wnt1-Cre;lox-Sun1-GFP mice were acutely dissected and freshly frozen in OCT. Cryosections (10 μm) were cut using a cryostat (Thermo Fisher Scientific) and mounted onto the 10x Visium Spatial Gene Expression Slide. Spatial transcriptome sequencing libraries were prepared with 10xGenomics Visium Spatial Gene Expression Slides & Reagent kit according to manufacturer's construction
