Wagyu × Hereford crossbred cattle and purebred Hereford longissimus dorsi muscle multi-omic data (4, 12, 24 months)

Samples were collected from the longissimus dorsi muscle of WH crossbred cattle and purebred Hereford (HH) cattle raised under standardized conditions. The dataset includes snRNA-seq, stRNA-seq, snATAC-seq, and Hi-C data from 4-month-old samples, as well as snRNA-seq data from 12- and 24-month-old samples.

All data underwent rigorous quality control, sequence alignment, and normalization, with no systematic missing values. These data support research on the heterogeneity of fibro-adipogenic progenitors and key regulatory pathways, providing multi-omics foundational data for high-quality beef cattle crossbreeding and genomic selection programs.
