Figure 2: Aerosolized CBD oil and VEA accumulate on HBEC apical surfaces pre day 2 exposures.

Figure 2:

Transmission light micrographs acquired from HBE culture inserts exposed to (A) air, (B) PG/VG, (C) PG/VG + nicotine, (D) PG/VG + CBD oil, and (E) PG/VG + CBD oil + VEA. Representative images were collected from n=6 biological replicate cultures per exposure condition. The black arrow in (D) indicates droplet accumulation on PG/VG+CBD oil-exposed cultures. The white arrow in (E) indicates droplet accumulation on PGVG+CBD oil+VEA-exposed cultures. Scale bar = 200 μm.
