Fig. 2From: The protective roles of tea tree oil extracts in bovine mammary epithelial cells and polymorphonuclear leukocytesThe protective effects of TTO on bovine mammary epithelial cells (BMECs). (a) Evaluation of proliferative effects of TTO on BMECs. The BMECs were incubated with 0 (control group), 0.0125%, 0.025%, 0.05%, or 0.1% TTO for 6 h. (b) Viability of BMECs exposed to S. aureus with or without TTO treatment. BMECs were cultured in the absence of S. aureus and TTO (control group), in the presence of S. aureus and absence of TTO (S. aureus group), and in the presence of S. aureus and 0.0125%, 0.025%, 0.05%, or 0.1% TTO (TTO-treated groups) for 6 h. Data are presented as the means ± SEM (n = 4). Means at the different concentration of TTO with different letters (a-d) differ significantly for treatment effectBack to article page
