Fig. 11From: Photobiological modulation of hepatoma cell lines and hepatitis B subviral particles secretion in response to 650 nm low level laser treatmentThe comparisons of the nuclear surface area of HepG2 cells between non-irradiated group (A) and irradiated groups (E) at 96 h incubation post-laser irradiation by TEM Assay. Significant differences between control (A) and their respective experimental groups are represented on the bar columns as P ≤ 0.05 (*)Back to article page
