(A) Schematic diagram of the experimental procedure. Each plot represents the date of passaging, with over nine passages during the culture period. (B) Time course of PDLs of YAC-treated HPAEpiC cultures. (C) Phase contrast images of YAC-treated HPAEpiCs (passage 3). Scale bar: 100 μmBack to article page
