Bright field microscopy of porcine chondrocytes cultured for 18 days on colloidal gels. In (a), the biomaterial gel has broken down. In (b), the cells are in between the colloidal gel and some cells are sitting atop the gel.
(a) Porcine chondrocytes attaching to the colloidal gel. Day 18 (degrading gel) 40x. Scale bar = 25 μm
(b) Porcine chondrocytes attaching to the colloidal gel. Day 18 (viscous gel) 40x. Scale bar = 25 μm
