Optimal cutting temperature (OCT) blocks (Scigen 4586, USA) were made according to the Visium Spatial Protocols – Tissue Preparation Guide (Document CG000240). The OCT blocks from the experimental group were created 6 hours after injecting human stem cells. For each sample of all the classes, two tissue slices were acquired from each OCT mold. One was prepared for H&E staining, and the other was kept as a fresh frozen slice for Visium ST library. Spatial transcriptome sequencing libraries were prepared with 10x Genomics Visium Spatial Gene Expression Slides & Reagent kit according to manufacturer's construction.
