Figure 4

Redox-based color-coded images extracted based on endogenous TPEF images are superimposed on THG-based lipid content (magenta) images. The same scaffold is imaged after 2, 5 or 9 weeks in either adipogenic (top row) or propagation (bottom row) media. Scale Bar= 35µm. Redox scale color bar is shown on the right. Endogenous silk fluorescence is shown in grayscale.
