英文摘要: Abstract(#br)During the healing process after bone fracture, soft callus forms adjacent to the fracture site, is replaced by hard callus, and is finally remodeled to the original bone configuration. Although the cambium layer of the periosteum is reported to play an essential role in callus formation, we still lack direct in vivo evidence of this. To investigate the cell lineage of the soft callus, we analyzed the process of fracture healing in Prx1 - Cre;ROSA26 reporter ( R26R ), Col1a1(3.6 kb) - Cre;R26R , Col1a1(2.3 kb) - Cre;R26R , Sox9 - CreERT2;R26R , and Sox9 - LacZ mice with X-gal staining. In the Prx1 - Cre;R26R , in which the cells of the periosteum stained for X-gal before fracture, all cells in the soft callus were X-gal positive, whereas in the Col1a1(3.6 kb) - Cre;R26R mice,...
