hUCMSC-encapsulated CPC constructs and effect of fiber volume fraction on: (A) flexural strength, (B) elastic modulus, and (C) work-of-fracture (toughness). Each construct contained 50 vol% alginate hydrogel beads with 150,000 hUCMSCs. The CPC control with 0% chitosan and 0% fibers is included at the lower right corner. Each value is mean ± sd; n = 5. Increasing the fiber volume fraction in the hUCMSC-encapsulated construct increased the mechanical properties (p < 0.05).
