| Using flow cytometry, 234 Macoma balthica were examined during a survey to determine frequency of neoplasia in the Gulf of Gdansk (Poland). Clams were collected in 4 locations and DNA content in gill tissue cells was determined by flow cytometry using propidium iodide staining. Cell permeabilization was induced by osmotic shock. Prevalence of neoplasia ranged from 9.6 to 26.7 % depending on location. DNA content in aneuploid cells was higher than in normal dividing cells. The fluorescence value for aneuploid cells corresponded to tetraploid/pentaploid cells. Three stages of neoplasia were defined, based on the percentage of aneuploid cells determined by flow cytometry. Histopathological and cytogenetic analyses were also carried out on the same clams for... |
