FIG. 1.
Schematic of microsphere incorporation within self-assembled tissue rings. (A) Gelatin microspheres (purple circles) were mixed in suspension with SMCs (black dots) at 0, 0.2, or 0.6 mg/106 cells. (B) Cells and microspheres were seeded into agarose molds. (C) Cells aggregate to form self-assembled rings with incorporated microspheres. (D) Photograph of an agarose mold with aggregated human SMC-microsphere rings. Arrowheads point to rings on agarose posts. SMC, smooth muscle cell.
