Figure 7: Fibroblast culture, 760 nm excitation wavelength. (a) Fibroblasts, before UVB irradiation, appearing as elongated cells; both the cellular bodies and the dendrites show an autofluorescent signal coming from the cytoplasmatic granules. (b) After UVB irradiation, some fibroblasts undergo morphologic alterations corresponding to necrosis.
