简介：
Overview
This article presents a protocol for inducing chondrogenic differentiation of adipose-derived stem cells (ASCs) using centrifugal gravity (CG). The method highlights the potential of mechanical stress in cartilage repair by promoting the upregulation of SOX9, leading to the development of chondrogenic phenotypes.
