A Multi-omic Atlas of Human Embryonic Skeletal Development -Multiome GEX+ATAC
Two distinct and anatomically restricted modes of ossification, which are endochondral ossification and intramembranous ossification, govern osteogenesis and joint formation throughout the human skeleton and, to our knowledge, the cellular bases by which they form and mature remain incompletely described in human development at single-cell resolution. To address this, we apply single-nuclei paired RNA and ATAC sequencing to decipher the molecular gene regulatory programmes that mediate maturation of the distinct bone and joint-forming niches in the cranium and appendicular skeleton across space and time from 5-11 PCW.
