1Single-cell RNA Sequencing Reveals Thoracolumbar Vertebra Heterogeneity and Rib-genesis in Pigs显示文摘Development of thoracolumbar vertebra(TLV)and rib primordium(RP)is a common evolutionary feature across vertebrates,although whole-organism analysis of the expression dynamics of TLV-and RP-related genes has been lacking.Here,we investigated the single-cell transcriptome landscape of thoracic vertebra(TV),lumbar vertebra(LV),and RP cells from a pig embryo at 27 days post-fertilization(dpf)and identified six cell types with distinct gene expression signatures.In-depth dissection of the gene expression dynamics and RNA velocity revealed a coupled process of osteogenesis and angiogenesis during TLV and RP development.Further analysis of cell type-specific and strand-specific expression uncovered the extremely high level of HOXA103′-UTR sequence specific to osteoblasts of LV cells,which may function as anti-HOXA10-antisense by counteracting the HOXA10-antisense effect to determine TLV transition.Thus,this work provides a valuable resource for understanding embryonic osteogenesis and angiogenesis underlying vertebrate TLV and RP development at the cell type-specific resolution,which serves as a comprehensive view on the transcriptional profile of animal embryo development.Jianbo Li Ligang Wang Dawei Yu Junfeng Hao Longchao Zhang Adeniyi C.Adeola Bingyu Mao Yun Gao Shifang Wu Chunling Zhu Yongqing Zhang Jilong Ren Changgai Mu David M.Irwin Lixian Wang Tang Hai Haibing Xie Yaping Zhang 2021Genomics, Proteomics & Bioinformatics2021,19,3:1
