Figure 7. Quantification of cell number on ADA-GEL hydrogels compared to alginate by image analysis.

Figure 7

Number of NHDF on alginate and ADA-GEL hydrogels of different compositions after 4 days and 7 days of cultivation. Alginate was used as the control material. Asterisks denote significant difference compared with alginate films in each cultivation period, *p<0.05, **p<0.01 and ***p<0.001 (Bonferroni's post-hoc test was used). Cells could not be counted due to the agglomeration of cells on alginate hydrogel after 7 days of cultivation.
