Figure 4. Microdrop printing of cell-laden hydrogels into native-like tissue architectures.

(a) Schematic of the fabrication process and future applications of the developed platform (Illustration made by Tolpa Studios). (b) Various printed cell-laden microgel patterns. (c) hMSCs spreading within the patterned microgels (Green is obtained by filtering the brightfield channel with imageJ to remove noise-peaks). (d) Spatially controlled differentiation of hMSCs inside the patterned microgels.
