Evidence of CTR and CK expressions in OCLs at day 28. a Micrographs of CTR staining (replicates per NaCl concentration). Scale ba r= 100 μm. b The means of the percentages of CTR-positive cells in the different culture conditions (at least five representative fields of view per condition). c Micrographs of CK staining (replicates per NaCl concentration). Scale bar = 100 μm. d The means of the percentages of CK-positive cells in the different culture conditions (at least five representative fields of view per condition). The respective statistical analyses are presented, and symbols indicate significant differences (p < 0.05)
