摘要:
Summary—The geometrical characteristics of fibrillar organizations are studied by electron microscopy in structures obtainedin vitroin cell‐free assembled collagen gels, andin vivoin dermal tracts of anuran skin. We analyze several characteristics of the fibrils including the diameter, the outline, the curvature and the extrafibrillar space. We analyze also the variation of fibrillar orientation (twist) in longitudinal and transverse thin sections of these structures. The results are compared in theDiscussionto determine to what extent these fibrillar patterns are similar to liquid crystalline organizations and to what extent they result from a self‐assembly or a cell‐assembly
