Abstract

Background: One source of non-immunogenic bone graft is Bovine Hydroxyapatite (BHA), but it is lacking in the potential for osteoinduction. Recent research has shown that demineralized freeze-dried bovine xenograft (DFDBX) has the potential for osteoinduction and contains transforming growth factor β (TGF β) and Bone Morphogenic Protein (BMP) which trigger differentiation of Bone Marrow Messenchymal (BM-MSC) into osteoblasts. This study was conducted to assess the potential for osteoinduction in vitro using human adipose derived mesenchymal stem cells (hAD-MSC) by comparing proteins that express RUNX-2 and ALP on BHA that have been used and commercialized compared to new materials developed by DFDBBX. Objective: to determine the expression of RUNX-2 protein and ALP protein in hAD-MSC cultures after exposure to DFDBBX and BHA. Method: hAD-MSC cultures were divided into 4 groups which were 2.5% DFDBBX conditioned medium, 2.5% BHA conditioned medium, positive control (osteogenic medium), and negative control group (containing the basic medium of cell growth) and then planted in slide on the microplate. Observation of RUNX-2 and ALP expression was carried out after 2, 7 and 14 days of culture with the western blot methods. Result: The results of the study carried out using western blot examination and ImageJ software showed that there were differences in the number of RUNX-2 and ALP expressions on days 2, 7 and 14. Conclusion: Through this research it can be proven that there are expressions of RUNX-2 protein and ALP protein in Human adipose mesenchymal stem cell cultures after exposure to DFDBBX and BHA with Western blot examination methods.
