Fish Melanophores & Adrenaline

Time lapse at 7x speed of the response of fish (tilapia) melanophores to 200uM adrenaline/epinephrine, captured in Western Africa during the ASCB molecular cell biology workshop in Ghana. Fish melanophores are a great, readily available, and easy to analyse cell for understanding aspects of the signalling and cytoskeleton of eukaryotic cells. This video shows the pigment (melanin) particles (melanosomes) in the cells (melanophores) moving along microtubules towards the centrosome in response to adrenaline, a response the fish uses to change colour from dark to light. calculatedimages.blogspot.co.uk/2013/07/cell-biolo…
