In Vitro Characterization of Multilamellar Fibers with Uniaxially Oriented Electrospun Type I Collagen Scaffolds

Figure 8

Raman confocal maps of four different specimens showed the distribution of glycosaminoglycans (blue) and hydroxyproline (red). The images display close distribution of glycosaminoglycans and hydroxyproline at 856 cm⁻¹ and 1062 cm⁻¹, respectively, in cell-loaded cross-linked collagen electrospun scaffold and naive intervertebral disc.
