... antibodies directed against fibrin, fibronectin isoforms, collagens IV and VI, laminin and tenascin. The findings suggest two structurally and immunohistochemically different subtypes of fibrinoid: fibrin-type fibrinoid and matrix-type fibrinoid. Fibrin-type fibrinoid was characterized by immunoreactivity...

...L. Pannarale; P. Braidotti; L. d’Alba; E. Gaudio Previous studies on collagen fiber orientation have led to different interpretationsand theories about the fiber arrangement in the lamellar compact bone. The purpose of this investigation was to provide new and more in-depth data on fiberarrangement...

...Y. Ohsaki; K. Nagata; K. Kurisu The detailed distribution of types 1 and III collagen and fibronectin was studied in the developing mouse palatal shelf using a double immunofluorescence technique. Just prior to palatal shelf elevation, type I collagen showed denser localization on the nasal side...

... observed by other authors. Skinfold thickness was significantly correlated with vertebral (r = 0.364, p < 0.0001) and femoral BMD (r = 0.486 p < 0.0001). Skin and bone are connective tissues whose extracellular matrix mainly contains type I collagen. It is postulated that age-related skin atrophy...

...I. Mizoguchi; M. Nakamura; I. Takahashi; M. Kagayama; H. Mitani The immunohistochemical localization of types I and II collagen was examined in the following 4 cartilaginous tissues of the rat craniofacial region: the nasal septal cartilage and the spheno-occipital synchondrosis (primary cartilages...

...M. Järvinen; L. Jozsa; M. Kvist; M. Lehto; T. Vieno; J. Isola; P. Kannus The collagen composition and ultrastructural organization of the myo-fascial junction was studied using immunohistochemical techniques and electron microscopy. At the myo-fascial junction, a small amount of type-III collagen...

...B. Zimmermann Mineralization at collagen fibrils is regulated by glycosaminoglycans (GAG). Alterations in proteoglycan composition during mineralization as well as inhibition of mineralization by GAGs are well documented. Collagen-GAG interactions during desmoid osteogenesis in fetal rat calvariae...

.... Isolated notochordal fragments were cultured in suspension in liquid medium. Native striated collagen fibrils with a period of 540 Å were observed in the perinotochordal sheath. Fine granular and filamentous materials suggestive of proteoglycans have been observed in intercellular spaces and under...

... sulphate, chondroitin sulphate) could be detected in the sarcolemma. Type IV and type Vcollagen and laminin were found exclusively in the sarcolemma and endomysium. Type I and type III collagen as well as fibronectin were detected both in the endomysium and perimysium. 11 05 1988 5 07 1988 15...

... corresponding to the degree of mineralization. Isolated bone fractions were analysed for their content in collagen and non-collagenous proteins. The results showed marked differences between compact and spongy bones, this latter containing higher proportions of little mineralized bone particles than the former...

..., the intermediate region of the interventricular septum remained heterogeneous. Localized accumulations of collagen were seen in all regions of the left ventricle and interventricular septum. From these results we conclude that in thyrotoxic myocardial hypertrophy the isozymic shift from V 3 to V 1 is progressive...

...Eleuza M.V.G. Martello; P.A. Abrahamsohn The distribution of collagen and reticular fibers was studied in the endometrium of virgin and pregnant mice. The collagen and reticular fibers were examined in picrosirius-stained sections observed in a polarizing microscope and in silver-impregnated...

..., II and IV and elastase, and may be a false basal lamina. The basal lamina of cells with pigment granules which surround the capillary was digested by collagenase IV and elastase, and contained type IV collagen. Fibrils between the basal lamina like membrane of the pecten capillary endothelium...

... in showing the presence of two distinct collagen populations, segregated into different compartments of each artery. The fibrous component of the tunica media was comprised of reticulin fibers, which displayed a distinct argyrophilia when studied by means of the silver impregnation technique, and showed up...

... mesothelial cells. These cells possess numerous micropinocytotic vesicles; a conspicuous basal lamina separates the mesothelium from the underlying connective tissue. Most of the material found between the two serous coverings consisted of a three-dimensional meshwork of abundant collagenous fibers...

...Kiyoshi Shimizu; Tetsuo Furuya; Yuji Takeo; Kazuhiko Shirama; Kyutaro Maekawa The collagen content of the mouse uterus increases during pregnancy and rapidly decreases to the level of nulliparous mice within a few days post partum. Most of the hydroxyprohne in the uterine collagen had disappeared...

...Manuel de Jesus Simões; Osvaldo Alves Mora; Ricardo M. Oliveira-Filho Uteri of rats that had been either oophorectomized or given a single dose of 17β-diethylstilbestrol or progesterone were studied as to the ultrastructural features of collagen resorption by the fibroblasts of the endometrial...

...Kiyoshi Shimizu; Kyutaro Maekawa † This study was undertaken to determine where most of the uterine collagen is degraded during the postpartum involution. The greater part of uterine collagen, which was estimated as hydroxyproline, had disappeared by day 2 post partum. Colchicine, which decreases...

...A. Horvath; R. Cabrera; E. Vial Collagen and elastic fibres were stained in cryostatic slices of various tissues with the MBTH reaction, specific for aldehyde groups. Depending on the source, collagen and elastin gave different colours, easy to distinguish. It appears that this simple technique...

...N.Z. Zambrano; G.S. Montes; K.M. Shigihara; E.M. Sanchez; L.C.U. Junqueira The collagen arrangement of different cartilages of several mammals was studied by the Picrosirius-polarization method applied to tissue sections whose proteoglycans had been previously removed by enzymatic digestion...
