Stem cells serve as promising candidates for regenerative medicine. The migration capability of stem cells may determine the treatment efficacy. Currently, chemotaxis and thigmotaxis are two plausible approaches to regulate cell migration behaviors, with thigmotaxis requiring actual contact between the cell and an external substrate. Collagen, a main component of the extracellular matrix, is promising for regulating cell behaviors. However, few studies have focused on revealing the regulatory effect of collagen on cell migration, especially the relationship between collagen configuration and s...
