Project description:Age and skeletal maturity impacts the capacity for bone regeneration. Using a mouse model of large-scale rib resection, we demonstrated that skeletally immature mice regenerate the rib around 14 days post resection, whereas skeletally mature mice never fully regenerate the rib. Here, we performed bulk RNA sequencing analysis of rib calluses from skeletally immature and mature mice at baseline, 0, 2, 5, and 14 days post-resection to characterize the age-related changes in gene expression profiles during the early and late stages repair of bone repair.

Using a mouse model of large-scale rib resection, we demonstrated that skeletally immature mice regenerate the rib around 14 days post resection, whereas skeletally mature mice never fully regenerate the rib. Here, we performed single-cell RNA sequencing analysis of rib calluses from skeletally immature and mature mice at 5 and 14 days post-resection to characterize the age-related changes in cell population frequencies and their gene expression profiles during the early and late stages repair of bone repair.
Project description:The mature and immature FF samples were subjected to mass spectrometry with the isobaric tags for relative and absolute quantification (iTRAQ). The differential proteomics between mature and immature FF revealed their striking differences in the protein components and functions, which may improve our knowledge of the follicular microenvironment and its biological roles for reproductive processes in yak.
Project description:We report screening of genes differentially expressed in cells isolated from immature and mature third molar teeth. Among them, a homeobox transcription factor, distal-less homeobox 4 (DLX4) was highly expressed in immature human dental pulp cells, and significantly enhanced iPSC colony formation in combination with OCT3/4, SOX2, and KLF4 to the level comparable with that using classical combination of Yamanaka's factors, OCT3/4, SOX2, KLF4, and c-MYC.
