Cells maintain proliferation and viability when treated with nintedanib. a Proliferation rate of HUVECs, NL-FBs, and co-culture. Cells were imaged and counted after live/dead staining, and the proliferation rate was determined by calculating the ratio of live cells on each day to the number of cells originally seeded on day 0. Each condition was assessed in duplicate, with at least four sample images used for counting. b Viability of HUVECs, NL-FBs, and co-culture. The assay was performed in three independent experiments with duplicate wells
