    “…Surprisingly, there was no evidence that the recruitment of innate immune cells to fractures or soft callus formation was altered in wnt16 mutants. However, osteoblast recruitment was significantly delayed in wnt16 mutants postfracture, coinciding with precocious activation of the canonical Wnt signaling pathway. …”

    “…Furthermore, skull fractures do not offer an indication of the stage of healing on radiologic studies because they do not heal with callus formation as seen with long bone fractures. …”

    “…The results showed that relatively high concentrations of NAA (0.5 mg l(−1)) and 2,4-D (0.5 mg l(−1)) in the MI medium were essential for protoplasts to form cell walls and maintain cell divisions, and thereafter auxin should be reduced for callus formation and shoot induction. For shoot regeneration, relatively high concentrations of cytokinin were required, and among all the combinations tested, 2.2 mg l(−1) TDZ in combination with auxin 0.5 mg l(−1) NAA gave the best result with up to 45% shoot regeneration. …”

    “…Following positive–negative selection to exclude transgenic cells randomly transformed with T‐DNA, piggyBac‐mediated transgenesis from the extrachromosomal dsT‐DNA was successful in ca. 1% of transgenic callus lines. After temporary expression of CRISPR/Cas9 within piggyBac, we confirmed, in a proof‐of‐concept experiment, that piggyBac could be excised precisely from the genome via the stably transformed transposase PBase. …”

    “…In the femur fracture model, micro-CT analysis showed that albiflorin played a positive role in the formation of callus in the early stage of fracture recovery, and histological examination proved to induce the expression of osteogenic genes in femur tissue. …”

    “…Zileuton showed a beneficial effect on trabecular vertebra, while the femur was negatively affected. Callus formation was enhanced by all treatments; however, its density and biomechanical properties were unaltered. …”

    “…Using a mouse tibial bone fracture model in vivo, we show that application of a low intensity constant EM field source enhanced fracture repair via improved biomechanical properties and increased callus bone mineralization. Overall, this study provides supporting evidence that EM field therapy promotes bone fracture repair through mitochondrial OxPhos activation.…”

    “…The density of VEGF and CD34 showed that the angiogenesis processes were different in the bone fracture area and callus tissue in the Fx +WTS subgroups. The serum levels of VEGF, TGF-β, and IGF-1 were significantly lower in the Fx +WTS42 group, and PTH in the Fx +WTS28 group was higher than that in the other groups. …”

    “…Strikingly, the gene editing rate was increased to 60% on average and up to 100% in some experiments when the Cas12a RNP was co-delivered with a PMI selectable marker gene cassette and the induced callus cultures were selected with mannose. We also show that use of higher activity Cas12a mutants resulted in improved editing efficiency in more recalcitrant target sequence. …”
