Figure 5.

Alginate fiber size. Representation of alginate fiber size depending on the injection speed with (A) 1.5% or (B) 0.5% of alginate. Statistics is represented with letters when comparisons were made between the different injection speeds for each needle size. Same letters represent no significant differences (p > 0.05), whereas different letters represent statistical differences (p < 0.05) (n = 12). Red dashed line indicates an appropriate size of alginate fiber diameter to encapsulate alginate/HA microparticles from 100 to 300 µm.
