Collagen Fibrils within the Renal Glomerulus
The fine structure of the frog glomerulus has been described in detail by Pak Poy (2); the present observations confirm his findings as far as its principal structure is concerned. He pointed out that the main morphological difference between the frog glomerulus and those of mammals is in the basement membrane, that is, the structure between endothelial and epithelial (podo-cyte) cells. Beneath...
متن کاملThe Occurrence of Crystals within Collagen Fibrils
Earl ier electron microscope studies have provided circumstant ial evidence for the existence of crystals within the collagen fibrils 1 of bone matr ix. In fully calcified bone matr ix there are no areas which are not replete with crystals; a finding which indicates tha t there should be a deposition of crystals not only a t the per iphery of fibrils but within them as well (12). The posit ion ...
متن کاملSize exclusion and diffusion of fluoresceinated probes within collagen fibrils.
The diffusion of fluoresceinated probes inside single collagen fibrils was investigated by imaging the migration of fluorescence along the fibrils in oil and by monitoring fluorescence recovery after photobleaching (FRAP). Probes were excluded from the fibrils according to their size. Probes that were not excluded diffused in the fibrils, but FRAP occurred 6 x 10(-4) times more slowly than in w...
متن کاملThe renal glomerulus in hypoxic cor pulmonale.
We measured the mean capillary tuft area by a custom-built semi-automatic technique in postmortem sections from the kidneys of 16 patients with "blue and bloated" chronic bronchitis and emphysema and in seven patients of similar age who were free of respiratory and renal disease at death. Nine bronchitic patients had received domiciliary oxygen treatment while seven had not. The mean glomerular...
متن کاملElectron Microscopy of the Avian Renal Glomerulus
Electron microscopy of sections of chicken glomeruli shows them to possess a large central cell mass, occupying the hilum and the centre of the glomerulus, and continuous with the adventitia of the afferent and efferent arterioles. The glomerular capillaries form a much simpler system than in mammals and are spread over the surface of the central cell mass. Between the capillaries the mass is l...
