... their early life experiences predict high environmental variability in the future. We reared fish under constant (water) or fluctuating (water–air) environments until adulthood and assessed a suite of traits along the oxygen cascade (e.g. neuroepithelial cell density and size, cutaneous capillarity, gill...

...Cosima S. Porteus; Patricia A. Wright; William K. Milsom Serotonin containing neuroepithelial cells (NECs) are putative oxygen sensing cells found in different locations within the gills of fish. In this study we wished to determine the effect of sustained internal (blood) hypoxaemia versus...

...(neuroepithelial cells), airways (neuroepithelial bodies) and vasculature(carotid bodies) that initiate cardiorespiratory reflexes, oxygen sensitive chromaffin cells associated with systemic veins or adrenal glands that regulate the rate of catecholamine secretion, and vascular smooth muscle cells capable...

...Emily H. Coolidge; Cosima S. Ciuhandu; William K. Milsom SUMMARY We investigated the distribution of serotonin (5-HT)-containing neuroepithelial cells (NECs), the putative O 2 sensing cells, in the gills of four species of fish: trout ( Oncorhynchus mykiss ), goldfish( Carassius auratus ), trairão...

...Michael G. Jonz; Colin A. Nurse SUMMARY Previous studies have described the morphology, innervation and O 2 -chemoreceptive properties of neuroepithelial cells (NECs) of the zebrafish gill filaments. The present work describes the ontogenesis of these cells, and the formation of functional O 2...
