影响干细胞分化的能力是非常可取的,因为它将帮助我们在各个方面改善患者的临床结果。以前已经研究过许多不同的技术来实现这一点。然而,这项简明的研究侧重于细胞生长的地形。如果植入物不能与周围的骨骼结合,并且通常会形成软组织界面,从而减少直接的骨接触,那么目前的非骨水泥型骨科植入物可能会失败。在这里,我们看看先前报道的纳米拓扑学的效果,该纳米拓扑术利用纳米无序影响间充质基质细胞(如在骨髓中发现)向骨分化,并对成熟的成骨细胞(如在骨骼中发现的)施加这种影响。由于地形是一种物理技术,因此可以设想将其用于一系列材料中,例如用于制造矫形植入物的聚合物和金属。
The ability to influence stem cell differentiation is highly desirable as it would help us improve clinical outcomes for patients in various aspects. Many different techniques to achieve this have previously been investigated. This concise study, however, has focused on the topography on which cells grow. Current uncemented orthopaedic implants can fail if the implant fails to bind to the surrounding bone and, typically, forms a soft tissue interface which reduces direct bone contact. Here, we look at the effect of a previously reported nanotopography that utilises nanodisorder to influence mesenchymal stromal cell (as may be found in the bone marrow) differentiation towards bone and to also exert this effect on mature osteoblasts (as may be found in the bone). As topography is a physical technique, it can be envisaged for use in a range of materials such as polymers and metals used in the manufacture of orthopaedic implants.
