According to researchers from Universidad de Chile, a cannabidiol (CBD) oil-in-water nanoemulsion shows promising antitumor effects in canine mammary carcinoma cell lines. Cancer cells readily absorbed the formulation, and at 50 µM it significantly reduced their viability while being less toxic to non-cancerous cells. The study concludes by stating:To our knowledge, this is the first study to evaluate the effects of CBD incorporated into nanoemulsion (CBD-Nem) on mammary canine cancer cells, with results that could support future clinical trials. The above hypothesis is supported within this paper because CBD-Nem prevented the colony formation (20 days) of canine cancer cells. Further research is needed to elucidate molecular mechanisms underlying the observed effects and the therapeutic potential in canine mammary cancer.
