Late mineralization data. (A and B) Optical micrographs showing crystal formation on elastin fibers after 24 h mineralization by the free drift method, indicating presence of crystals on the fiber vertices. (Magnifications: A, ×20; B, ×200.) (C) Synchrotron x-ray diffraction pattern from the same conditions (λ = 0.6525 Å).
