Proliferation of myogenic progenitor cells following feeding in the sub-Antarctic notothenioid fish Harpagifer bispinis
Feeding metabolism and the activation of myogenic progenitor cells were investigated in the fast myotomal muscle of the sub-Antarctic fish Hapagifer bispinis acclimatized to either simulated summer (10degreesC; 18h:6h light:dark) or simulated winter (5degreesC; 6h:18h light:dark) conditions.
