Abstract (original English)

ABSTRACT The disrupted surface of porous membranes, commonly used in tissue-chip and cellular co-culture systems, is known to weaken cell-substrate interactions. Here, we investigated whether disrupted surfaces of membranes with micron and sub-micron scale pores affect YAP localization and differentiation of adipose-derived stem cells (ADSCs). We found that these substrates reduce YAP nuclear localization through decreased cell spreading, consistent with reduced cell-substrate interactions, and in turn enhance adipogenesis, while decreasing osteogenesis.
