Figure 2
Characterization of size, swelling behavior, permeability and mechanical stability of freshly prepared beads (ALG and ALG-CS), beads soaked in CaCl2 solution or beads soaked in cell culture medium for 3 days.
(a) Diameters of both beads under different conditions. (b) Volume swelling degrees of both beads soaked in culture medium. (c) Permeability of both beads under different conditions. (d) Rupture rate (Rrup) of both beads under different conditions. Data are represented as the means ± SD of three independent experiments. **P < 0.01, comparison between ALG and ALG-CS. ##P < 0.01, comparison among groups under different conditions.
