Fig. 6 in Comparative evaluation of coelomocytes in Paracentrotus sea urchins: Description of new cell types and insights on spherulocyte maturation and sea urchin physiology

Fig. 6. Morphometry of different morphotypes (M1 to M3) of spherulocytes in Paracentrotus sea urchins. A, D, and G – Nucleus diameter; B, E, and H – Cytoplasm diameter; C, F, and I – Nucleus/Cytoplasm Ratio. Capital letters – P. gaimardi, Small letters – P. lividus. For each parameter, distinct letters show significant differences among stages (p <0.05), with uppercase to P. gaimardi and lowercase to P. lividus. Asterisk (*) shows significant differences between species (p <0.05). Legend: N/C ratio = Nucleus/Cytoplasm Ratio.
