WebMar 20, 2024 · Moreover, the effects of TQR exposure on iridophores were also evaluated. To exclude interferences between iridophores and melanophores and investigate the particular influence on chosen cell type, the 9-hpf embryos were exposed to the mixture of 0.2 mM PTU and increasing doses of TQR—1 µM, 10 µM, and 50 µM, respectively. The term chromatophore was adopted (following Sangiovanni's chromoforo) as the name for pigment-bearing cells derived from the neural crest of cold-blooded vertebrates and cephalopods. The word itself comes from the Greek words chrōma (χρῶμα) meaning "colour," and phoros (φόρος) meaning "bearing".
