Features of Microsystems for Cultivation and Characterization of Stem Cells with the Aim of Regenerative Therapy

Schematic representation of concave microwell generation utilizing surface tension force. First, the pentagonal-shaped microwells were filled with prepolymer solution and exposed to squeezing/suction. Concave wells were created by a little residual polymer solution due to the surface tension. The ESCs were then injected into microchannel (and microwells) for trapping a uniformal quantity of ESCs to produce the same-sized EBs.
