Fig. 4. Differences in haemocyte morphology observed in vitro, in the presence and absence of plasma. (A) Haemocytes with plasma, spread on uncoated 24-well culture plate (1 h incubation); scale bar, 10 µm. (B) Rounded haemocytes without plasma, attached to uncoated 24-well culture plate (1 h incubation); scale bar, 10 µm. (C) Haemocytes with plasma, spread on surface of DEAE Sepharose beads (1 h incubation); scale bar, 80 µm. (D) Rounded haemocytes without plasma, attached to surface of DEAE Sepharose beads (3 h incubation); scale bar, 80 µm.
