Role of Vibrational Spectroscopy in Stem Cell Research

Figure 1

Average raw FTIR spectra of mESCs in different stages of differentiation towards the formation of ESNCs using FPA microspectroscopy (a). Spectra were normalized over the range of 4000–1000 cm⁻¹. (b) shows an enlargement of the lipid spectral region from 2800 cm⁻¹ to 3000 cm⁻¹. (c) shows amides I and II spectral region from 1500 cm⁻¹ to 1800 cm⁻¹ for average second derivative spectra of mESCs in different stages of the ESNCs differentiation process after nine points of smoothing and normalization with EMSC.
