Time-course Raman spectroscopy of MSC grown in osteogenic medium. (A) Mean time-course Raman spectra of typical 210 × 210 mm2 regions of the cultures shown in C. Raman spectra were acquired at different time points for the same regions of the culture osteoblast in osteogenic medium and non-osteogenic medium. (B) Principal components used to extract meaningful chemical information (C) Maps corresponding to the PC2 scores recorded in the same culture regions at different measurements days. Scale bar: 10 μm.
