Biocompatibility in

<p>(A) The cell line L929 was cultured on a positive control substrate (Ctrl), on gelatin gel (g gel) and on quattroGel (qGel), metabolically marked with bromodeoxyuridine (BrdU, green) to identify mitotic cells and cytochemically labeled with fluorescent phalloidin (actin, red) and DAPI (blue) to display all cell nuclei. Pictures of individual rows represent corresponding images. Arrows mark cells in different stages of mitosis. Quantification of cell adhesion (B) and cell proliferation (C) indicate that no statistically significant differences exist between different substrates. n = 3, s.d., p<0.05. Scale bar: (A) 50 µm.
