Fig. 8: Oxygen imaging of Jurkat cells seeded in VitroGel.

a The cell seeding pattern for 0 K (CM), 5 K, and 50 K cells per well (n = 4). b pO2 maps of the wells at time t = 0 (~3.2 mm from the bottom of the wells). c Box plot of pO2 vs cell density at t = 0. There is a statistically significant difference between 5 K and 50 K cells (p < 0.0001), but no significant difference between CM and 5 K cells (p = 0.6581). d Plot of pO2 versus cell density (0 K, 5 K, and 50 K cells per well, n = 4) for HEK-293, Jurkat, and Jurkat in VitroGel. Error bars are standard errors.
