Advances in micropatterning technology for mechanotransduction research

Abstract

Micropatterning is a sophisticated technique that precisely manipulates the spatial distribution of cell adhesion proteins on various substrates across multiple scales. This precise control over adhesive regions facilitates the manipulation of architectures and physical constraints for single or multiple cells. Furthermore, it allows for an in-depth analysis of how chemical and physical properties influence cellular functionality. In this comprehensive review, we explore the current understanding of the impact of geometrical confinement on cellular functions across various dimensions, emphasizing the benefits of micropatterning in addressing fundamental biological queries. We advocate that utilizing directed self-organization via physical confinement and morphogen gradients on micropatterned surfaces represents an innovative approach to generating functional tissue and controlling morphogenesis in vitro. Integrating this technique with cutting-edge technologies, micropatterning presents a significant potential to bridge a crucial knowledge gap in understanding core biological processes.
