Abstract

Bone remodeling and immune function are dynamically regulated through cell-cell and cell-matrix interactions by stem and mature cell populations. We investigated the hypothesis that monocytes and pre-osteoblasts respond to cyclic tensile stress and paracrine interactions by differentiating into macrophage-like and osteoblast-like cells. 20% cyclic equibiaxial strain was applied to monocytic U937 and pre-osteoblastic ST2 cells for 72 h. Increased levels of CD11B, CD14, IL-6, and IL-8 in U937 indicated monocytic differentiation. Increased ALP expression and calcium deposition in ST2 indicated differentiation towards osteoblastic lineage. Overall, application of cyclic strain and pre-osteoblastic co-culture induced differentiation in this cyclically strained bone model.

在骨模型中,等双轴应变和前成骨细胞共培养的共刺激可分化单核细胞。
骨重塑和免疫功能是通过干细胞和成熟细胞群的细胞-细胞和细胞-基质相互作用动态调节的。我们研究了单核细胞和前成骨细胞通过分化为巨噬细胞样细胞和成骨细胞样细胞来响应循环拉伸应力和旁分泌相互作用的假设。将20%的循环等双轴菌株作用于单核细胞U937和成骨前ST2细胞72小时。U937中CD11B、CD14、IL-6和IL-8水平升高表明单核细胞分化。ST2中ALP表达和钙沉积的增加表明其向成骨细胞谱系分化。总的来说,应用循环应变和成骨前共培养诱导了这种循环应变骨模型的分化。图形化的简介:
