Note: for large Xenium datasets such as this one with > 200 million unique cell by transcript features (sparse matrix), Xenium Explorer v3.0+ does not support certain transcript and cell functions due to performance limits. See more information here.

Biomaterials
FFPE-preserved P1 mouse pup was purchased from AcePix Biosciences (Mouse C57BL/6, Non-diseased).
Tissue preparation
Tissues were prepared following the Demonstrated Protocols Xenium In Situ for FFPE - Tissue Preparation Guide (CG000578) and Xenium In Situ for FFPE Tissues – Deparaffinization & Decrosslinking (CG000580).
Probe hybridization, washing, ligation, amplification, and cell segmentation staining were performed following the Xenium Prime In Situ Gene Expression with optional Cell Segmentation Staining User Guide (CG000760).
Post-instrument processing followed the Demonstrated Protocol Xenium In Situ Gene Expression - Post-Xenium Analyzer H&E Staining (CG000613).
Gene panels
The Xenium Prime 5K Mouse Pan Tissue and Pathways Panel was designed to enable comprehensive cell type and cell state identification using publicly available single cell RNA sequencing data. The panels also cover canonical signaling pathways, as well as genes relevant to developmental biology and genes that are well known in biomedical literature.
In addition to the Xenium Prime 5K Mouse Pan Tissue and Pathways Panel, add-on probes were included for the canonical Snap25a (Snap25-201) / Snap25b (Snap25-202) isoforms. These isoforms are distinguished by a mutually exclusive fifth exon. To analyze these isoforms, a pair of probes were made for the exon-exon junction of each isoform (exon 4 to exon 5, and exon 5 to exon 6).
Xenium Analyzer
The instrument run was performed following the Xenium Analyzer User Guide CG000584. The on-instrument analysis was run with Xenium Onboard Analysis v3.0.0.
