Quantitative assessment of the content of S element and calcium ions incorporated within freshly prepared beads (ALG and ALG-CS), beads soaked in CaCl2 solution or beads soaked in cell culture medium for 3 days.

(a) S element content analysis of both beads under different conditions using an elemental analyzer. CS powder served as the control. (b) Weight of calcium ions incorporated within both beads prepared from 1 ml gelation solution (1 ml alginate solution with or without CS) under different conditions detected by ICP-OES. Data are represented as the means ± SD of three independent experiments, ##P < 0.01.
