(A) Hepatocyte proliferation in different bioinks determined as the percentage of the reduction of formazan crystals. (B) The cellular adhesion capability of the bioinks was measured by means of hemocytometer counting. (C) Fluorescence microscopy images depicting hepatocyte growth (stained in calcein-AM) on Day 5 in alginate, (D) CA 1:1, (E) CA 2:1, and (F) CA 1:2. The scale bar represents 250 μm. (∗p < 0.05).
