Figure 15 in The elasmoid scales of teleosts: from structure to bioinspired materials
Figure 15. – Cyprinus carpio. One step trichrome. Vertical section of the anterior margin of the scale. A thick membrane stained in green is observed between the epidermis and the dermis. Within the dermis, the peripheral scleroblasts form a rim around the margin of the scale (arrowheads). The elevation corresponds to the formation of the first circulus (arrow). Figure 16. – Carassius auratus. TEM. Section of the margin of the scale. A thin microfibrillar membrane (arrow) separates the epidermis (ep) from the dermis (d). Scale pocket cells (spc) form a rim around the scales and line the scleroblasts. The external layer, the first layer to be formed, is deposited between the episquamal scleroblasts (es) and the hyposquamal scleroblasts (hs). Figure 17. – Carassius auratus. Indirect immunofluorescence visualising microtubules in the episquamal scleroblasts. A: Phase constraste. B: Tyrtubulin Mts distribution. Mts radiate from the MTOCs (microtubule organising centre) in cells located between two circuli (c). Figure 18. – Carassius auratus. TEM. Episquamal scleroblats lining the external layer. Figure 19. – Margin of the scale. Elevation of the external layer forming a circulus (c). Figure 20. – Carassius auratus. TEM.

Figure 24. – Carassius auratus. TEM. Section of a partially demineralized circulus. The external layer (el) is composed of network of randomly dispersed collagen fibrils. A thin layer of microfibrillar material is deposited on one side of the circulus. bp: basal plate; es: episquamal scleroblast. Figure 25. – Carassius auratus. TEM. Demineralized section. Detail of the organic material of the limiting layer (ll) made of a thin microfibrillar meshwork and the external layer (el) composed of thin collagen fibrils embedded in a matrix. Figure 26. – Cyprinus carpio. TEM. Demineralized section of the upper part of the scale. Bundles of collagen fibres forming Sharpey-fibre-like bundles (Sf) cross the external layer (el) and the limiting layer (ll).

Figures 37-46. – Carassius auratus. Figures 37-40. – TEM Control scales. Figure 37. – Flat hyposquamal scleroblasts (hs) synthesise the thick collagen fibrils of the plywood-like structure of the basal plate and the thin TC fibres (tc) crossing the plywood-like structure. Figure 38. – Collagen fibrils are coaligned with the Mts and micro- filaments (arrows) underlying the plasma membrane of the hyposquamal scleroblast. Figure 39. – Detail of the secretory surface of a hyposquamal scleroblast. The microfibrils and the Mts have changed their direction and are coaligned with the newly synthesized collagen fibrils forming a new layer. Figure 40. – Detail of the secretory surface of a hyposquamal scleroblast. Mts (arrowhead) located in the vicinity of the plasma membrane are in parallel with the innermost thick collagen fibrils. Figures 41- 44. – Four-day-regenerating scale. Figure 41. – TEM. The hyposquamal scleroblasts are tall prismatic cells with well-developed RER and Golgi areas. Figure 42. – Freeze-fracture. Gap junction between two hyposquamal scleroblasts. Figure 43. – TEM. The innermost collagen fibrils and the Mts
Figures 1-8 in The elasmoid scales of teleosts: from structure to bioinspired materials
Figures 1-8. – Morphological aspects of elasmoid scales. Figures 1, 2. – Cycloid Scale of Carassius auratus. 1: Scale stained with alizarin red S. 2: SEM. The circuli (c) are more spaced in the exposed posterior field than in the overlapped anterior field. Insert: Note the presence of denticles (arrow) on the apex of the circuli. c: circuli; f: focus of the scale; r: radius. Figure 3. – Cycloid scale of Gaidropsarus vulgaris stained with alizarin red S. The circuli form regularly spaced out ridges concentrically disposed around the focus of the scale. The radii are oriented along the anteroposterior axis of the scale. Figure 4. – Ctenoid scale of Solea solea stained with alizarin red S. The posterior part of the scale is ornamented with denticles: the cteni (ct). The radii (r) are parallel and oriented along the anteroposterior axis of the scale. Figure 5. – SEM. Detail of the posterior part of the ctenoid scale of Coryphaenoides rupestris, which bears long fusiform cteni. Figure 6. – Posterior part of a scale of Solea solea stained with alizarin red S. At the margin of the scale, the most recent ctenii form acute denticles whereas the oldest progressively resorbed appear as truncated spines (asterisk). Figure 7. – Cycloid scale of Trisopterus luscus (Linnaeus, 1758) stained with alizarin red S. Numerous radii (r) span out from the focus (f) to the periphery of the scale. Figure 8. – Regenerating scale of Trisopterus luscus stained with alizarin red S showing an organization resembling that of the regular developed scales (Fig. 7). Figure 9. – Scale growth. Labelling in successive times with three different fluorochromes of a scale of Hemichromis bimaculatus Gill, 1862, fluoresceine: yellow-green, tetracycline: yellow and xylelol orange: red, reveals the successive mineral deposits during the scale growth. The unmineralized radii (r) are not labelled (micrograph: F.J. Meunier).
Figure 27 in The elasmoid scales of teleosts: from structure to bioinspired materials
Figure 27. – Etelis carbunculus Cuvier, 1828. Ground section. Polarised light. Black and white superimposed collagenous plies are characteristic of an orthogonal plywood-like structure. The basal plate (bp) is partially mineralized. Mandl corpuscles (arrow) are observed at the level of the front of mineralization. (micrograph: F.J. Meunier). Figure 28. – Macrourus berglax Lacepède, 1801. SEM. Broken freezed scale showing the lamellar structure of the basal plate. The direction of the collagen fibrils of adjacent layers are at right angle to one another forming an orthogonal plywood-like structure. Figure 29. – Poecilia reticulata Peters, 1859. TEM. Rapid freeze anhydrous techniques. Front of mineralization (mf) in the basal plate (bp). Figure 30. – Poecilia reticulata. TEM. Rapid freeze anhydrous techniques. The crystals are located in the spaces surrounding the cross-sectioned collagen fibrils that appear electrolucent. Figure 31. – Carassius auratus. TEM. Demineralized section. The superimposed plies of the basal plate (bp) are crossed by the TC fibres (tc) that arise from the hyposquamal scleroblasts (hs) and reach the external layer (el). ll: limiting layer Figure 32. – Carassius auratus. TEM. Rapid freeze anhydrous techniques. The characteristic aspect of the front of mineralization is due to the presence of the TC fibres (tc). It differs from the smooth one of Poecilia reticulata, which has no TC fibers (Fig. 29). Figure 33. – Poecilia reticulata. TEM. Mineralized corpuscles, Mandl corpuscles (mc), are located ahead of the front of mineralization. Figure 34. – Carassius auratus. TEM. Mandl corpuscles (mc) located ahead of the front of mineralization. Figure 35. – Trisopterus luscus. SEM. The front of mineralization is ornamented with fused Mandl corpuscles. Figure 36. – Cyprinus carpio. SEM. Mandl corpuscles and the mineralization front show a ridged surface due to the presence of TC fibres.
