Bone Regeneration by Homeopathic Symphytum officinale

Cell therapy has been proposed as an effective treatment method for bone regeneration using stem cells and osteogenic inducting mediators. In the present study, the ability of homeopathic remedy Symphytum officinale to induce osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells (rat BM-MSCs) was studied MSCs were isolated from the rat’s bone morrow. Cytotoxic effect of Symphytum on the MSCs was evaluated by MTT assay. The osteogenic induction ability of Symphytum has been assessed by alizarin red staining (ALZ) and quantitative alkaline phosphatase (ALP) activity assays and compared with the osteogenic standard medium. MTT assay results illustrated that Symphytum 200 C had a high cytotoxicity (to about 75.2 ± 3.12), so that lower potencies were used for the next experiments. Symphytum 6 C had the most color intensity in ALZ and ALP staining assays. Also, quantitative analyses of ALP activity revealed that Symphytum 6 C caused the most increase in the ALP activity up to 4.04 ± 0.34 and 7.86 ± 1.38 on day 7 and 21, respectively. According to this finding, Symphytum could enhance osteogenic differentiation of MSCs and can be considered as a safe, low cost, and highly effective drug for bone regeneration. Cell therapy has been proposed as an effective treatment method for bone regeneration using stem cells and osteogenic inducting mediators. In the present study, the ability of homeopathic remedy Symphytum officinale to induce osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells (rat BM-MSCs) was studied. The results illustrated that Symphytum 6 C had the most osteogenic induction effect compare with osteogenic standard medium. According to this finding, Symphytum officinale as a natural compound can significantly induce osteogenic differentiation of rat BM-MSCs. So, it could be considered as a safe and more cost-effective therapeutic agent for clinical treatment of bone disorders.
