Fig. 1 in Comparative evaluation of coelomocytes in Paracentrotus sea urchins: Description of new cell types and insights on spherulocyte maturation and sea urchin physiology

Fig. 1. Live and stained mature coelomocytes in Paracentrotus sea urchins. A-L – coelomocytes of P. gaimardi; M-X – coelomocytes of P. lividus. A, G, M, and S – Phagocytes; B, H, N, and T – Vibratile cell; C and I – Crystal cell; O and U – Progenitor cell; D, J, P, and V – Red spherulocyte; E, K, Q, and W – Colorless spherulocyte; F, L, R, and X – Granular spherulocyte. Columns A-F and M-R – Live cells; Columns G-L and S-X – Stained cells; A-B and D-F – Differential interference contrast; C and M-R – Light microscopy; G, J-L, S, V inset, W and X – Mallory's trichrome; H–I, T-V, and X Inset – Toluidine blue. Black arrowhead = Flagellum; white arrowhead = crystalloid; Arrow = nucleus. Scale: A-X = 10 μm; Insets = 5 μm.
