Role of Vibrational Spectroscopy in Stem Cell Research

Figure 3

Three-dimensional plot of covariance ellipsoids of a LDA classification model for hMSCs with stimulation (w), without stimulation (w/o), with glycogen accumulation (g), and with high expression of calcium phosphate salts (c). The intensities of the three variates were ratioed against the intensity at 1653 cm⁻¹.
