Multiphoton microscopic images of the Vybrant DiD-labelled MG-63 cells after 24-hour-long cultivation on the surfaces of ʺtissue cultureʺ plastic plates (a) or PSIDAB (b) or PASPDAB based (c and d) fibrous membranes and PASPDAB membrane without cells as a control (e). The cells show red fluorescence due to the Vybrant DiD staining while the green color indicates the autofluorescence of the PSI or PASP membranes. Red and green channels are both shown on all pictures except the (e) where only the green was active. Viability of MG-63 cells after 1- or 3-day-long cultivation on the surfaces of ʺlow cell bindingʺ plastic plates (control) and PSIDAB or PASPDAB membranes (f). * p < 0.05 compared to the control. + p < 0.05 compared to day 1.
