Studies on Blood Capillaries
The pathway by which intravenously injected ferritin molecules move from the blood plasma across the capillary wall has been investigated in the muscle of the rat diaphragm. At 2 min after administration, the ferritin molecules are evenly distributed in high concentration in the blood plasma of capillaries and occur within vesicles along the blood front of the endothelium. At the 10-min time po...
متن کاملColony Forming Unit Endothelial Cells Do not Exhibit Telomerase Alternative Splicing Variants and Activity
Introduction: Endothelial progenitor colony forming unit-endothelial cells (CFU-EC) were first believed to be the progenitors of endothelial cells, named endothelial progenitor cells. Further studies revealed that they are monocytes regulating vasculogenesis. The main hindrance of these cells for therapeutic purposes is their low frequency and limited replicative potentials. This study was unde...
متن کاملMorphological classifications of vertebrate blood capillaries.
BENNETT, H. STANLEY, JOHN H. LUFTANDJAMES C.HAMPTON. Morphological class$kations of vertebrate blood capillaries. Am. J. Physiol. Ig6(2): 381-390. I g5g.Morphological features of blood capillaries from various vertebrate forms and organs are presented. Simple classifications are proposed, based on presence or absence of continuous basement membrane, on the nature of the endothelial cell and on ...
متن کاملMechanics of Blood Flow in Capillaries
Blood is a concentrated suspension of red blood cells (RBCs). Motion and deformation of RBCs can be analyzed based on knowledge of their mechanical characteristics. Models for single-file motion of RBCs in capillaries yield predictions of apparent viscosity in good agreement with experimental results for diameters up to about 8 μm. In living microvessels, flow resistance is also strongly influe...
متن کاملSynthetic Capillaries to Control Microscopic Blood Flow
Capillaries pervade human physiology. The mean intercapillary distance is only about 100 μm in human tissue, which indicates the extent of nutrient diffusion. In engineered tissue the lack of capillaries, along with the associated perfusion, is problematic because it leads to hypoxic stress and necrosis. However, a capillary is not easy to engineer due to its complex cytoarchitecture. Here, it ...
