Fig. 2. Cellular viability during primary culture of hepatocytes from common eelpout (Z. viviparus). The number of viable cells (circles), expressed relative to the initial cell number, and the fraction of dead cells (triangles) in total cell counts were determined for cells from warm-acclimated animals during primary culture at either 11°C (shaded symbols) or 4°C (open symbols). Values are means ± s.e.m. (N=3).
