Figure 3 in Shell formation in two species of bivalves: the role of mantle cells and haemocytes
Figure 3. Graphical elaboration of the outer margin mantle of Polititapes aureus and Cerastoderma glaucum. The stain used is AB/PAS. OF = outer fold; MF = medium fold; IF = inner fold.
Figure 2 in Shell formation in two species of bivalves: the role of mantle cells and haemocytes
Figure 2. Macroscopic evaluation of Cerastoderma glaucum. Yellow-white, sometimes light brown, curved shell with typical heart shape when viewed in profile. Very pronounced ribs. Interior of shell milky white. Shell of medium size with thick ribs and knobby formations at growth striae. Right valve with two main teeth and the two anterior and posterior secondary teeth.
Figure 6 in Shell formation in two species of bivalves: the role of mantle cells and haemocytes
Figure 6. Transverse section of outer margin of coat of Polititapes aureus, 20×, 40×; scale bars, 20μm, 50 μm. Epithelial cells immunoreactive for S100 (green) and 5-HT (red) are colocalized and evident (arrowheads). Haemocytes reactive for S100 and 5HT are notable and well colocalized in the epithelium and subepithelium (arrows). Epithelial cells immunopositive for iNOS and TLR2 are noticeable and well colocalized (arrowheads). Immunoreactive haemocytes that colocalize for iNOS and TLR2 are evident (arrows) in epithelium and subepithelium. In addition, some haemocytes are positive only for iNOS (*) others only for TLR2 (double arrows), suggesting a different hemocyte population with different function. The 'display profile' function of the confocal microscope confirms the colocalization.
Figure 1 in Shell formation in two species of bivalves: the role of mantle cells and haemocytes
Figure 1. Macroscopic evaluation of Polititapes aureus. Moderately convex valves of more or less ovoid or slightly elongated shape with pale yellow, white, or chestnut colour with broken zig-zag lines, or with dark chestnut-coloured spots.
Figure 4 in Shell formation in two species of bivalves: the role of mantle cells and haemocytes
Figure 4. Transverse section of outer margin of mantle of Polititapes aureus, 100×. Mallory histologic staining shows the presence of a cuboidal epithelium (*) that becomes columnar (**) toward the outside of the margin. With AB/PAS histochemical staining, mucous cells rich in acidic mucopolysaccharides (amc) appear evident (arrowhead), with their secretion being shed outside the cell. In addition, ciliated epithelial cells (cec) are evident in both staining, scale bar 100 μm.

Fig. 3 in Evolutionary and developmental aspects of phalangeal formula variation in pig-nose and soft-shelled turtles (Carettochelyidae and Trionychidae)
Fig. 3 Hyperphalangy charac- terizes trionychid but not carettochelyid turtles. Adult Carettochelys insculpta (MTD 30761) show elongated phalanges and the formula 2-3- 3-3-3 for both manus (a) and pes (b). In Cyclanorbis senegalensis the formula for the manus is 2-3-3-6-5 (c; MTD 44951) or 2-3-3-5-4 (d; MTD 39162). (e) Manus of Pelodiscus sinensis (MTD 30740), formula 2-3-3-5-5. The phalangeal formula for the pes is less variable; Lissemys punctata (MTD 32372) exhibits the formula most frequent in trionychids, 2-3-3-4-3 (f). Note that the trionychid phalanges of digits I and II are much more robust than those of the other digits, and that the terminal phalanges of digits IV and V can be very small. Roman numerals denote digits, Arabic numerals the number of phalanges of the labelled digit
