Abstract: A method of enhancing osteogenic differentiation using vitamin D treatment is disclosed. The method utilizes the combined effect of vitamin D treatment and flow-induced shear stress in a modified perfusion bioreactor to treat the bone defect. The method comprising the steps of: isolating adipose tissue from a subject by liposuction; separating adipose-derived stem cells from the adipose tissue; pre-treating the separated adipose-derived stem cells for a predefined time 20 to 40 minutes with vitamin D3; seeding the pre-treated stem cells onto one or more scaffolds; washing of unattached stem cells from the scaffolds after a predefined time of 20 to 30 minutes; culturing the stem cell seeded scaffold by utilizing a modified perfusion bioreactor to form a tissue-engineered construct, where flow induced shear stress is applied, and implanting the tissue-engineered construct into the subject without a need to obtain autologous bone graft.
