Fig. 3From: Photobiological modulation of hepatoma cell lines and hepatitis B subviral particles secretion in response to 650 nm low level laser treatmentHepG2 and HepG2.2.15 cell morphology examined by phase contrast light inverted microscope at 96 h. × 100 post-laser irradiation, no morphological alterations were observed in both cell lines (HepG2 and HepG2.2.15); however, there was a decrease in cells condensation in irradiated groups of 4, 8, and 10 J/cm.2Back to article page
