Method Abstract: "[Investigators] have cultured two cell types in 3D native collagen type I scaffolds, and measured the O(2) tension at specific locations within the scaffold." P.4014 right column 4th paragraph: "Fibre-optic oxygen probes (Oxford Optronix, UK) were inserted into the centre of the 3D constructs to place the measuring tip halfway along their long axis (Fig. 1)."
Comments P.4016 right column 2nd paragraph: "For HDFs [Human dermal fibroblasts], the average value of Vm [oxygen consumption rate constant] over the time period shown in Fig. 2b is 1.19×10^−17 mol/cell/sec. For HBMSCs [Human bone marrow-derived stem cells], the average value of Vm over the time period shown in Fig. 3b is 7.91×10^−18 mol/cell/sec." P.4018 right column 5th paragraph: "From [investigators’] simulations, [they] find that the number of HDFs (Vm = 1.19×10^−17 mol/cell/sec) in the construct should not exceed 1.80 million, which is a cell density of 2.00×10^7cells/cm^3. Similarly, the number of HBMSCs (Vm = 7.91×10^−18 mol/cell/sec) in the construct should not exceed 2.70 million, which is a cell density of 3.00×10^7cells/cm^3."
