Fig. 12From: Photobiological modulation of hepatoma cell lines and hepatitis B subviral particles secretion in response to 650 nm low level laser treatmentHepG2.2.15 cells of the control group (non-irradiated cells) showed I fairly regular cell membrane. Euchromatic nucleus with irregular nuclear membrane, (yellow line), and peripheral nucleolus, (yellow bars), the diameter of the nucleolus (1.5 μm), nucleus surface area length was (24,196.90 μm2). Fat droplet, (orange par), the diameter was (1.7 μm). Different size mitochondria, with preserved cristea, (green arrows). × 5600. II Fairly regular cell membrane. Euchromatic nucleus with irregular nuclear membrane, (yellow arrow). Nucleus surface area was (30084.75 μm2). Fat droplets, (orange arrows), the diameter was (3 μm).
