While various material factors have been shown to influence cell behaviors, recent studies started to pay attention to the effects of some material cues on “subcellular” geometry of cells, such as self-deformation of cell nuclei. It is particularly interesting to examine whether a self deformation happens discontinuously like a first-order transition and whether subcellular geometry influences significantly...
We herein report a material technique to control the shapes of cell nuclei by the design of the microtopography of substrates to which the cells adhere. Poly(d,l-lactide-co-glycolide) (PLGA) micropillars or micropits of a series of height or depth were fabricated, and some surprising self deformation of the nuclei of bone marrow stromal cells (BMSCs) was found in the case of micropillars with a sufficient...
