Fig. 6From: Two-photon FLIM of NAD(P)H and FAD in mesenchymal stem cells undergoing either osteogenic or chondrogenic differentiationFLIM of FAD in MSCs during osteogenic differentiation. a Pseudocolor-coded images of the protein-bound (t1) and free (t2) forms of FAD. Field of view 213*213 μm (512*512 pixels). b Dynamics of the fluorescence lifetimes of free and protein-bound forms of FAD and fluorescence lifetime contributions of the protein-bound forms of FAD in MSCs. Mean ± SD. *Statistically significant difference with undifferentiated MSCs on the same day. P values are shown.
