Microtubules and Microfibrils in Human Platelets

Thrombosis and Haemostasis, 1966
SummaryThe 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.

Extracellular microfibrils in development and disease

Cellular and Molecular Life Sciences, 2007
Fibrillins 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 ...

Structure of the α-keratin microfibril

Journal of Molecular Biology, 1976
The fine detail in the X-ray diffraction pattern of α-keratin has been explored out to spacings of 4 A by a direct mapping of the cylindrically averagedintensity transform. The meridional maxima lie on a set of layer lines corresponding to an axially projected repeat of structure of 470 A, and the distribution of nonmeridional maxima is consistent with

Thrombin Stimulated Release of Platelet Microfibrils

British Journal of Haematology, 1974
Summary. Platelets, separated from plasma by gel filtration, were exposed to a low level of thrombin prior to negative staining and examination by electron microscopy. Microfibrils with dimensions consistent with the contractile protein of platelets, thrombosthenin, were observed to radiate from the platelet surface.

Periodic Disorder along Ramie Cellulose Microfibrils

Biomacromolecules, 2003
Small angle neutron scattering studies have been carried out on cellulose fibers from ramie and Populus maximowicii (cotton wood). Labile hydrogen atoms were replaced by deuterium atoms, in water-accessible disordered regions of the fibers, to increase the neutron scattering contrast between the disordered and crystalline regions.

Possible Roles of Microfibrils in Elastogenesis

Connective Tissue Research, 1981
On 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.

Microfibrils from the Arterial Subendothelium

1999
Microfibrillar structures of the subendothelium are represented by either type VI collagen or elastin-associated microfibrils which are also referred to as fibrillin-containing microfibrils. These structures are present throughout the subendothelium irrespective of the presence of elastin.

Microfibril orientation in plant cell walls

Planta, 1970
The distribution of particles on the surface of the plasmalemma in the collenchyma of Apium graveolens was studied by the freeze-etching technique. The aim was to determine whether the distribution of particles was related to the known longitudinal or transverse orientation of cellulose microfibrils in different layers of the walls of these cells ...

Microfibril formation in chick notochordal cells

Tissue and Cell, 1982
The central parts of the chick notochord at Hamburger and Hamilton's stages 20-22 were investigated by electron microscopy. Electron-dense bodies of various sizes and shapes and bounded by a limiting membrane were found in the central cells the notochord.

Exploring the Nature of Cellulose Microfibrils

Biomacromolecules, 2015
Ultrathin 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 ...
