TABLE 2.

Effect of CB NPs on cellular viability of LβT2 cells or primary cultures of anterior pituitary cells.

CB NPs (μg/mL)	0	25	50	75	100
LβT2	100	99 ± 2	101 ± 3	101 ± 2	97 ± 1
Pituitary primary culture	100	–	107 ± 3	–	106 ± 2

LβT2 cells and primary cultures of anterior pituitary cells were treated with increasing concentrations of CB NPs (25–100 μg/mL) for 24 h and the MTT-based colorimetric assay was used to quantify cell viability. Absorbance was read at 575 nm and data are expressed as percentage over untreated cells and are the mean ± SEM from 4 independent experiments. Statistical differences were determined by non-parametric Kruskal-Wallis test followed by Dunnet’s multiple comparison test. Data showed no statistical significance.
