LUHMES 3D model for acute, recovery, and resilience experiments. a LUHMES differentiated in 3D on a gyratory shaker showing b RFP-expressing cells (red) and TH (green), nuclei (blue). c LUHMES 3D treatment and wash-out scheme for recovery and resilience (second hit) experiments and endpoints. d Medium rotenone quantification prior to treatment, day 8 and day 15. From left to right, bars correspond to negative control (medium without rotenone), positive control (medium with rotenone prior to treatment), 24 h treatment control (medium with rotenone in plates), 24 h treatment (medium with rotenone in plates with aggregates), 7 day wash-out control (medium with rotenone in plates on day 15 after wash-out), and 7 day wash-out treated cells (medium with rotenone in plates on day 15 after wash-out with aggregates). e Amount of rotenone bound to plastic and cells after 24 h exposure (day 8).
