Table 3.

Content of naphthoquinone pigments in cultivated cells of sea urchins S. intermedius and S. mirabilis in different media: SW—seawater; CFn—coelomic fluid obtained from intact sea urchins; CFreg—coelomic fluid obtained from injured sea urchins. Data are presented as the mean ± standard error from two independent experiments (ESI MS) [37].
