Tw. Matschak et Nc. Stickland, THE GROWTH OF ATLANTIC SALMON (SALMO-SALAR L) MYOSATELLITE CELLS IN CULTURE AT 2 DIFFERENT TEMPERATURES, Experientia, 51(3), 1995, pp. 260-266
Temperature is known to affect fish growth, and in Atlantic salmon the
re is an influence on muscle cellularity. Primary muscle cell culture
makes it possible to investigate direct effects of temperature on myog
enic cells. Salmon myosatellite cells were cultured for the first time
in this study. The cells were cultured at either 5 degrees C or 11 de
grees C. Increased temperature led to an increase in differentiation r
ate and especially hypertrophic growth (Q(10) = 4.0). No nuclear proli
feration was evident in the satellite cell population isolated at eith
er temperature. This may be due to the presence of different subpopula
tions of myogenic cells at different developmental ages or the presenc
e of indirect factors in vivo.
