Abstract

Tissue-engineered bone grafts require an osteoblastic cellular source to be utilized in bone transplantation therapy. Human bone marrow stem cells (hBMSCs) and periosteal-derived stem cells (hPCs) are the commonly used cellular sources for bone tissue engineering and are essential in fracture healing. In the present study, hBMSCs and hPCs were co-cultured from the same donors, as the cellular source. In monolayer cultivation, co-culturing hBMSCs and hPCs demonstrated more robust mineralized nodule formation and stronger alkaline phosphatase (ALP) positive staining than hBMSCs or hPCs. Three-dimensional (3-D) culturing on porous β-tricalcium phosphate (TCP) scaffolds and co-culturing of hBMSCs and hPCs significantly promoted the osteogenic specific mRNA expression of COL1α1, BMP-2, osteopontin (OPN) and osteocalcin (OC). For in vivo bone formation and neovascularization assessment, the cellular-β-TCP scaffolds were transplanted into critical-sized femoral condyle defects in rabbits. The results confirmed that co-culturing hBMSCs and hPCs accelerated bone regeneration and enhanced mature bone formation, but also facilitated central vascularization in scaffold pores. Based on these data, we recommend co-culturing hBMSCs and hPCs as a promising cellular source for bone tissue engineering applications.
