Reports a spatially resolved single-nucleus atlas of the postnatal mouse heart and introduces PIP-seq, a probe-based, high-throughput in vivo perturbation platform.
Key Takeaways
- The study integrated single-nucleus RNA sequencing with image-based spatial transcriptomics to map postnatal heart maturation across space and time.
- PIP-seq was developed to detect sgRNA identity, infer CRISPR editing, and profile transcription from fixed nuclei at scale.
- Using PIP-seq, the authors identified 21 previously uncharacterized regulators required for cardiomyocyte maturation roles like sarcomere assembly and metabolic reprogramming.
