A potential therapy of human umbilical cord mesenchymal stem cells for bone regeneration on osteoporotic mandibular bone

ABSTRACT

Objective: The aim of this study is to prove that human umbilical cord mesenchymal stem cell (hUCMSC) therapy on mandibular osteoporotic model is able to increase transforming growth factor-beta-1 (TGF)-β1 expression, Runx2, and osteoblasts. Materials and Methods: This research is true experimental posttest control group design. Thirty female Wistar rats were divided into 6 groups randomly, which consisted of sham surgery for control (T1), ovariectomy as osteoporotic group (T2), osteoporotic group injected with gelatine for 4 weeks (T3), 8 weeks (T4) injected with hUCMSC-gelatine for 4 weeks (T5) and 8 weeks (T6). All mice were presented for immunohistochemistry examination for TGF-β1, Runx2, and histology for osteoblasts. Results: The lowest level of osteoblast was osteoporotic group injected with gelatine in 4 weeks compared to other groups. There were increases of TGF-β1, Runx2, and osteoblasts from osteoporotic group compared to osteoporotic post-hUCMSC-gelatine injection group. Conclusion: The hUCMSC has a high osteogenic effect and increases the osteoporotic mandibular bone regeneration on the animal model that is showed by the increase of the level of TGF-β1, Runx2, and osteoblasts.
