Aflat tissue engineered skin (thickness 2.9 mm) is attached to the bottom of a dish and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). the diffusivity of oxygen in the skin is 2.20e-9 m2/s, and according to experiments that you’ve performed, you want to make sure that the concentration of oxygen in the device doesn’t fall below 0.065 mol/m3. (below that concentration harms the cells.) the rate of oxygen consumption is -2.5e-15 mol/[cell◦s]. what is the maximum cellularity (in cells/ml) that this tissue engineered skin can support?
