(a) Micro-CT images of different groups in different planes at 4 weeks. (b) Micro-CT images of different groups in different planes at 8 weeks. (c-e) Quantitation of bone volume to total volume (BV/TV), bone mineral density (BMD), and trabecular separation (Tb.Sp). Scale bar: 2 mm. *p < 0.05. Six individual samples in each group were analyzed. Data were presented as mean ± SD of six biological replicatesBack to article page
