Single-cell RNA sequencing for osteochondral fusions

ABSTRACT: We have developed a protocol to generate hPSC-derived osteochondral fusions that mimick embryonic long bone diaphysis. hPSCs were first differentiated to chondroprogenitors and osteogenesis-committed early chondrocytes. Then they were centrifuged together to genrate a fusion construct. After cultured for 7 days in vitro, the fusion construct was transplanted under the kidney capsule of the NOD/SCID mice to generate a mature osteochondral fusion. The 4-week osteochondral fusion grafts contain full spectrum of cells during endochondral ossification, mimicking the in vivo growth plate tissues of early long bone diaphysis. To exam this tissue in single-cell level for comparison with the published datasets of the true human emrbyo, we conducted single-cell RNA sequencing on the 4-week osteochondral fusion grafts.
