Micro-patterning cells through geometrically defined adhesion sites allows controlling morphogenesis, polarity, cellular mechanics, proliferation, migration, differentiation, stemness, cell–cell interactions, and collective cell behavior. Consequently, generating micro-patterned therapeutic cells is a promising idea that has not yet been realized and few if any steps have been undertaken in this direction. Prof. Rolauffs and his team aim to expedite the development of patterned cell populations using cell-instructive biomaterials for improved functional control as drug delivery systems in the context of cells as pharmaceutical products.
