OssiGel-primed human bone marrow mesenchymal stromal/stem cells show rapid chromatin remodeling at chondrogenic loci and an early chondro-progenitor population by 3 days that correlates with successful endochondral ossification recapitulation.
- Why it matters: Early molecular and cellular events that prime BM-MSC commitment to endochondral ossification are unclear, and donor-to-donor variability in chondrogenic potential limits mechanistic studies.
- What they did: The study used multi-omics profiling of OssiGel-primed BM-MSCs, combined with single-cell multi-omics in an in vivo tissue-engineering context, and identified LINC02511 as an enhancer-associated element; CRISPR silencing tested its role.
- The result: LINC02511 is present in human skeletal atlases, and its CRISPR-mediated silencing significantly impaired EO, providing a framework linking enhancer and non-coding RNA changes to early lineage specification.
