Abstract: The present disclosure relates to a culture scaffold for promoting differentiation from stem cells or precursor cells into osteoblasts, in which the culture scaffold includes a structure composed of a ridge and a groove, a kit using the culture scaffold, and a method for differentiating stem cells or precursor cells into osteoblasts. The culture scaffold of the present disclosure has an optimal pattern depending on the type of stem cells or precursor cells, thereby improving the osteoblast differentiation potency. In particular, it has a feature of showing excellent osteoblast differentiation potency even if only a small amount of supplementary factors inducing osteoblast differentiation is added. Furthermore, since the osteoblast differentiation potency is not greatly influenced by the change in cell density, it is possible to induce differentiation into osteoblasts without being influenced by the inflammatory environment formed by the inflammatory factors that increase upon cell differentiation.
