Microfluidic generation of biomimetic ovarian microtissue and on-chip extraction of the microtissue from oil emulsion into isotonic aqueous solution: (a) A schematic overview of the microchannel system. (b) A 3D zoomed-in view and real image of the dispatching channel and flow-focusing junction (FFJ) showing the non-planar design of the FFJ. (c) An image of the extraction channel at its entrance. (d) An image of the extraction channel at its end. The symbol q represents the flow rate of the aqueous core flow of sodium alginate; I-1, I-2, I-3, I-4, and I-5 represent the five inlets; O-1 and O-2 represent the two outlets; and λ≤1 [107].
