We studied the interaction of human buccal mesenchymal stem cells (MSCs) and osteoblasts differentiated from them with the surface of titanium samples. MSCs were isolated by enzymatic method from buccal fat pads. The obtained cell culture was presented by MSCs, which was confirmed by flow cytometry and differentiation into adipocytes and osteoblasts. Culturing of buccal MSCs on titanium samples was accompanied by an increase in the number of cells for 15 days and the formation of a developed network of F-actin fibers in the cells. The viability of buccal MSCs decreased by 8 days, but was restored by 15 days. Culturing of osteoblasts obtained as a result of buccal MSC differentiation on the surface of titanium samples was accompanied by a decrease in their viability and proliferation. Thus, MSCs from buccal fat pads can be used to coat implants to improve osseointegration during bone reconstruction in craniofacial surgery and dentistry. To improve the integration of osteoblasts, modification of the surface of titanium samples is required.
我们研究了人颊部间充质干细胞(MSCs)及其分化而来的成骨细胞与钛样本表面的相互作用。MSCs 通过酶消化法从颊脂垫中分离得到。获得的细胞培养物由 MSCs 组成,通过流式细胞术和分化为脂肪细胞和成骨细胞得到证实。颊部 MSCs 在钛样本上的培养伴随着细胞数量在 15 天内增加,并在细胞中形成发达的 F-肌动蛋白纤维网络。颊部 MSCs 的活力在第 8 天下降,但在第 15 天恢复。作为颊部 MSC 分化而来的成骨细胞在钛样本表面的培养伴随着其活力和增殖的下降。因此,颊部脂肪垫中的 MSCs 可用于涂层植入物,以改善颅面外科和牙科中骨重建期间的骨整合。为了提高成骨细胞的整合,需要对钛样本的表面进行修饰。
