Osteoinductivity performance dicalcium phosphate dihydrate-coated porous β-tricalcium phosphate granules in adipose-derived mesenchymal stem cells

Abstract

Elucidate the dicalcium phosphate dihydrate (DCPD)-coated-beta-tricalcium phosphate (β-TCP) porous granules osteoinductivity performance in adipose-derived mesenchymal stem cells (ADMSCs). β-TCP porous was made by adding the sodium chloride (NaCl) powders with the dry powder of DCPD and CaCO₃ in the concentrations 40:60 (by wt%). Then, DCPD layer will be formed on porous β-TCP granules by immersing the granules in an acidic calcium phosphate solution. ADMSCs cultured was used to examine the biocompability of 300–600 µm and 600–1,000 µm DCPD-coated-porous β-TCP by means of microculture tetrazolium technique (MTT assay) and scratch assay. Bone morphogenic protein-2 (BMP-2), Osterix, Runt-related transcription factor-2 (Runx2), Alkaline phosphatase (ALP), Osteopontin, Osteonectin expression were investigated. The DCPD-coated porous β-TCP granules were culture together with ADMSCs is biocompatible. BMP-2, Runx2, Osterix, ALP, Osteopontin, Osteonectin expression in ADMSCs after culture together with DCPD-coated-β-TCP significantly enhanced. DCPD-coated-porous-β-TCP granules have good biocompatibility and high osteoconductivity in ADMSCs.
