Viability of primary murine splenocytes in contact with 3D printed
materials. Primary splenocytes from male and female mice (Nmice = 2
per experiment) were evaluated by flow cytometry after live/dead staining with
Calcein-AM/7AAD. (A) Cell viability after 4 hr of direct physical
contact with PBS+incubation treated (T) or non-treated
(N) resins compared with well plate control
(C). Treated BioMed and Clear prints maintained relatively
high viability compared to the well plate, while BV007 did not. Bars show mean
± SD. One-way ANOVA per data set, ns > 0.06,
*p > 0.01, **p = 0.01,
****p < 0.0001. (B) Multiple
post-treatment methods (PBS, incubation at 37 °C, PBS+incubation, and
autoclavation) were evaluated using BioMed resin and culturing for 4 hours with
direct contact. Bars show mean ± SD. One-way ANOVA, ns
> 0.2, *p > 0.02. ****p <
0.0001. (C) Viability of direct contact (i.e. culture with resin)
and indirect contact (i.e. culture with resin leachate) of cells with treated
BioMed prints at 45 min, 4 hours, and 24 hours showed a decrease in viability
over time. Values show mean ± SD. One-way ANOVA at final time point,
****p < 0.0001.
