A) Schematic representation of nCol-F-Rh degradation inside the collagen gel. B) Control Collagen gel without nCol-F-Rh. C) and D) Confocal images Z-axis superposition of Collagen gel incubated with nCol-F-Rh for 18 h at physiological pH (C) and at Acid pH (D) for upper and lower fronts of the gel. Observation depth in each case were 300 μm for C and 320 <m for D, respectively. Images were taken each 2 μm. Scale bar: 20 μm.
