Structure and packing of microfibrils in collagen
Journal of Molecular Biology, 1973Abstract X-ray diffraction, patterns suggest that the five-stranded microfibrils in the collagen of rat tail tendon are supercoiled and packed together on a square lattice with a statistical distribution of axial displacements between nearest neighbours.

Extracellular microfibrils in development and disease
Cellular and Molecular Life Sciences, 2007Fibrillins are the structural components of extracellular microfibrils that impart physical properties to tissues, alone or together with elastin as elastic fibers. Genetic studies in mice have revealed that fibrillin-rich microfibrils are also involved in regulating developmental programs and homeostatic processes through the modulation of TGF-beta ...

Microtubules and Microfibrils in Human Platelets
Thrombosis and Haemostasis, 1966SummaryThe microtubules and microfibrils of human platelets are described. They are studied under conditions that give as little alterations as possible. Conclusions on their localisation in vivo are drawn and their possible role in maintaining the platelet shape is discussed.

Exploring the Nature of Cellulose Microfibrils
Biomacromolecules, 2015Ultrathin cellulose microfibril fractions were extracted from spruce wood powder using combined delignification, TEMPO-catalyzed oxidation, and sonication processes. Small-angle X-ray scattering of these microfibril fractions in a "dilute" aqueous suspension (concentration 0.077 wt %) revealed that their shape was in the form of nanostrip with 4 nm ...

Microfibrils are supramolecular structures ubiquitously found in the extracellular matrix of elastic and nonelastic tissues. The three members of the cysteine-rich fibrillin family constitute the core of microfibrils. Mutations in fibrillin-1 and -2 lead to a number of heritable connective tissue disorders termed fibrillinopathies.

Comparison of Rhapidosomes and Asbestos Microfibrils
Science, 1978Rhapidosomes (cylindrical nucleoprotein rods of bacterial origin) show great structural similarity to the microfibrils of chrysotile asbestos when negatively stained and observed with the electron microscope. If the negative stain is omitted, the asbestos retains its structural detail whereas the rhapidosomes appear to be unstructured bodies.

Possible Roles of Microfibrils in Elastogenesis
Connective Tissue Research, 1981On examination in the electron microscope elastic tissue is seen to consist of an amorphous component surrounded by microfibrillar components. The exact relationship between these components is unknown, although during development the microfibrils appear before the amorphous material.

Analytical Biochemistry, 1998
A method is described for the purification of collagen VI microfibrils and fibrillin-containing microfibrils, respectively. High M(r) microfibril-rich preparations isolated from nuchal ligament by bacterial collagenase digestion and size fractionation were purified by CsCl density gradient centrifugation.

The Supramolecular Organization of Collagen VI Microfibrils
Journal of Molecular Biology, 2003Collagen VI has a ubiquitous distribution throughout connective tissues, and has key roles in linking cells and matrix macromolecules. We have generated three-dimensional reconstructions of collagen VI microfibrils using automated electron tomography (AET) in order to obtain new insights into the organisation of collagen VI in assembled microfibrils ...

The substructure of α-keratin microfibrils
Journal of Ultrastructure Research, 1970The effect of underfocusing on the fine detail observed in the cross section of α -keratin microfibrils is discussed. It is shown that the apparent subdivision of the microfibrils into protofibrillar elements is coincidental with an underfocused granular phase image of similar dimensions and cannot, therefore, be accepted as a genuine structural ...
