Evaluation of Biochemical Changes in Skin-Derived Mesenchymal Stem Cells during In Vitro Neurodifferentiation by FT-IR Analysis

Figure 2

Normalized FT-IR spectra of S-MSC cultures propagated in neurodifferentiation medium at day 1 (w0), week 1 (w1), week 2 (w2), week 3 (w3), and week 6 (w6) in comparison with ReNcell CX cell line spectra and the HCA—vector normalization, Ward’s algorithm in the region 1775–997 cm⁻¹.
