(A) Effect of the algal extract on the viability of human skin fibroblasts (HSF), hepatoma cells (HepG-2), and breast carcinoma cells (MDA) at various concentrations (12.5–400 µg/mL) after 24 h (I) and 48 h (II) of treatment compared to untreated controls (mean ± SEM, n = 3; p < 0.05). (B) Representative phase-contrast micrographs showing morphological changes in HSF, HepG-2, and MDA cells following exposure to the algal extract at different concentrations (0, 50, 100, and 200 µg/mL).
