| Abstract | Previous culture techniques are often ineffective for providing appropriate conditions to cells grown in vitro for efficient growth and maturation. However, the advent of microfluidic chips allows us to manipulate various factors from co-culturing cells to inducing shear stress and biochemical gradient. The above have all been effectively applied to stem cell engineering, allowing dynamic interactions with other cells and, as a result, acquisition of a more mature state. The introduction of both synthetic and natural hydrogels into the chip provides more precise in vivo-like biophysical and biochemical cues to cells, enabling better recapitulation of the in vivo-like physiological behaviors and further maturation of stem cells even to the scale of organoids. This review addresses fundamental roles of microfluidic chips and hydrogels and how hydrogel-integrated chip systems provide breakthroughs in advanced stem cell engineering. |
