Figure Legend:
(a) Osmolality for each saline group. Osmolality increased linearly with PBS concentration (slope = 1851 mOsm/kg/M). (b) Percent change in saline osmolality after tissue swelling experiment (c) Swelling ratio was negatively correlated with the external osmotic environment (Pearson's: ρ < −0.55, p ≤ 0.001). Inset: Representative disk showing location and size of NP and AF tissue cores. * represents significant differences between the NP and AF swelling ratio at each osmotic condition (t-test, p < 0.01). (d) Swelling ratio normalized by the swelling ratio of the 0.15 M PBS group showed no significant differences between NP and AF explants (t-test: p = 0.4).
