Figure 4. Analysis of the biomechanical (panel (A)) and optical properties (panel(B)) of the native squid gladius (N-SG), cellularized squid gladius (C-SG) and native cornea (CTR). For the biomechanical properties, the Young modulus, strain at fracture and traction deformation values are shown. For the optical properties, the top figures show the gross transparency of each sample al located on a printed black letter, and the bottom figures correspond to the analysis of diffuse transmittance (MT), diffusereflectance (MR), reduced scattering (µs’) and absorption coefficient (µa) for each type of sample. Find out more.
Fig. 4 (Left) Absorption and (right) reduced scattering coefficients of the (a) global groups of samples, (b) global groups of times in culture, and (c) specific samples. Find out more.
