Fig. 4. Scanning elec­ tron microscope images of demineralized MB [(A) to (D)] and CB [(E) to (K)]. Demineralized, aldehyde-fixed (14) MB tissues from (A) MOR 1125, (B) extant laying hen, (C) emu, and (D) ostrich show random, crumbly texture. Organized collagen fiber bundles are not distinct in any sample because of rapid deposition and woven character. Scale bars for (A) and (B), 40 um; for (C) and (D), 20 um. Demineralized fragments of cortical bone from (E) MOR 1125, (F) chicken, (G) emu, and (H) ostrich are shown. A fibrous character dominates all samples. Scale bars for (E), (F), and (H), 30 mm; for (G), 10 mm. Higher magnification of demineralized CB from (I) MOR 1125, (J) emu, and (K) ostrich CB demonstrates the structural similarity between samples, although the MOR 1125 matrix is highly degraded. Scale bars for (I) and (K), 6 um; for (J), 5 um.
