| Popis: |
Although it is only comparatively recently that intermediate filaments (IF) have been recognized as a class of cytoskeletal structures, it is now more than 50 years since information was first collected on the three-dimensional structure of individual members of the class. For example, in discussing Speakman’s observations on the sorption of water by wool and his own x-ray studies of wool, Astbury (1933) stated that “A wool fibre... becomes as much as about 18% greater in diameter but only about 1% longer. This transformation is easily explained from the results of x-ray analysis, which shows that the regain water is for the most part spread over the surfaces of the tiny crystalline aggregates which are much longer than they are thick. Because the crystals are so very tiny, perhaps not more than some twenty times thicker than the water molecules themselves....” |
