Uptake of HpEVs by H. pluvialis cells. The uptake of the fluorescently labeled HpEVs (green) was evident in H. pluvialis cells after 24 h of incubation. No stain was revealed in the untreated cells (Scale bar = 10 µm). a H. pluvialis cells treated with PBS. b H. pluvialis cells treated with HpEVs-1. c H. pluvialis cells treated with HpEVs-2. d H. pluvialis cells treated with HpEVs-3. White arrows indicated the stained HpEVs
