Abstract
Cannabidiol (CBD), a phytocannabinoid derived from, has demonstrated therapeutic potential across various diseases, including cancer. This study evaluates the cytotoxic effects of CBD on three human cancer cell lines (HeLa, MDA-MB-231, and CaCo-2) and two non-cancerous cell lines (HaCaT and HUVEC) used as a control. Cells were treated with CBD at concentrations of 5, 10, and 20µM for 24, 48, 72, and 96 h. Cytotoxicity was assessed using MTT assays, nuclear morphology was evaluated via DAPI staining, and cell death mechanisms were analyzed through flow cytometry with apoptosis/necrosis markers. The LC50 values at 24 h were determined as follows: HeLa (9.4µM), MDA-MB-231 (10.3µM), and CaCo-2 (4.3µM). CBD treatment induced morphological changes characteristic of cell stress and death in cancer cells, observed by optical microscopy after 24, 48, 72, and 96 h of exposure. These findings highlight the potential of CBD as an adjunctive therapeutic agent for cancer treatment versus non-malignant cells.
