Large bone defects are a considerable challenge to reconstructive surgeons. Numerous traditional Chinese herbal medicines have been used to repair and regenerate bone tissue. This study investigated the bone regeneration potential ofDanggui Buxue Tang(DBT), a Chinese herbal decoction prepared fromRadix Astragali(RA) andRadix Angelicae Sinensis(RAS), from a molecular biology perspective. The optimal ratio ofRAandRASused inDBTfor osteoblast culture was obtained by colorimetric and alkaline

Moreover, the optimal concentration ofDBTfor bone cell culture was also determined by colorimetric, ALP activity, nodule formation, Western blotting, wound-healing, and tartrate-resistant acid phosphatase activity assays. Consequently, the most appropriate weight ratio ofRAtoRASfor the proliferation and differentiation of osteoblasts was 5 : 1. Moreover, the most effective concentration ofDBTwas 1,000 μg/mL, which significantly increased the number of osteoblasts, intracellular ALP levels, and nodule numbers, while inhibiting osteoclast activity. Additionally, 1,000 μg/mL ofDBTwas able to stimulate p-ERK and p-JNK signal pathway. Therefore,DBTis highly promising for use in accelerating fracture healing in the middle or late healing periods.
