The fungus Ophiocordyceps sinensis OS8 has been sourced from the wild variant of O. sinensis. In this study, the enriched β-D-glucan polysaccharide obtained from cultured mycelium of O. sinensis OS8 (OS8P) was examined for its potential to inhibit the growth of HepG2 liver cancer cells, and the IC 50 was 511.79 µg/mL. The study of cellular migration was analyzed by scratch assay. It was found that the HepG2 cell migration was significantly inhibited (P < 0.05) in the OS8P-treated group. The cell apoptotic feature's reliability was determined via DAPI staining to confirm the experimental results' reliability. The AO/PI double staining assay showed that HepG2 cells treated with OS8P (IC 50) had dead cells with condensed and shrieking nuclei that are late apoptotic. Morphological alterations were meticulously examined using scanning electron microscopy. The specific morphological characteristics of apoptotic cells, notably cell lysis, were distinctly observable. The damaged cells demonstrated severe structural disruption, loss of original shape, blebs formation, and apoptotic bodies' appearance. These findings provide pharmacological proof that the OS8P extract could be potentially employed in the food and medical industries for anticancer applications. [Display omitted] • Fungus O. sinensis OS8 as alternative source for biomedicine. • Its main bioactive compound is a β-D-glucan polysaccharide. • It has bioactivity against migration of liver cancer cells. • It has potential inducing liver cancer cell death via apoptosis.
