Fig. 6. Anisotropic cryogels improve cell alignment. (a–f) Confocal microscopy images showing an aminofluorescein-marked cryogel in green (a and d), cells marked with phalloidin in red (b and e) and cell nuclei counterstained in blue with DAPI. (c and f) Images showing merged channels. Scale bars = 100 μm. (g and h) Quantification of fibers and cell orientation. Graphs show frequency of fibers in each orientation degree.
