NOAA Tech Memo NMFS NWFSC-8: Contaminant Exposure in Juvenile Salmon (cont): Figure 12

Figure 12. The primary (represented by the lightly shaded bars in graph) and secondary (darkly shaded bar) in vitro plaque forming cell response per culture (PFC/culture) to TNP-LPS generated in the anterior spleen. The vertical bars represent one standard deviation above the mean. The mean PFC response was analyzed in chinook salmon from the Green-Duwamish system and the Nisqually system. Spleens from 10 chinook salmon were examined from each of the four locations. Spleen cells cultured only with tissue culture medium (background) did not produce more than a mean of 4 PFC/culture. *Indicate PFC/culture significantly higher in the primary response.
