E20 chicken lungs stored at -80°C until used for a Stereo-seq experiment. Cryo-sections were cut at the thickness of 10 μm and mounted on Stereo-seq permeabilization chips (210CP118) or transcriptomics chips (210CT114). Spatial transcriptome sequencing library was prepared using the library preparation kit (111KL114, STOmics) according to manufacture's instruction.
