Endothelial progenitor cell recruitment in a microfluidic vascular model

Biofabrication, 2015
During vessel injury, endothelial progenitors cells (EPCs) are recruited from bone marrow and directed to the hypoxic injury site. The hypoxic conditions in the damaged blood vessel promote TNF-α, which upregulates intercellular adhesion molecule-1 (ICAM-1). EPCs attach to endothelial cell lining using ICAM-1. Here we aimed to examine EPC attachment to

Effects of Hypercholesterolaemia on Physiological Recruitment of Coronary Vascular Reserve in Swine

Clinical Science, 1996
1. The endothelium participates in the regulation of coronary vascular tone. As evidence exists from studies performed on epicardial vessels that hypercholesterolaemia impairs endothelial function, we tested the hypothesis that hypercholesterolaemia impairs coronary vascular reserve in an intact animal. 2. Domestic swine, maintained on a

Pulmonary vascular resistance distribution and recruitment of microvascular surface area

Journal of Applied Physiology, 1994
To test the hypothesis that the distribution of hemodynamic resistance is involved in the control of pulmonary capillary surface area, we measured permeability-surface area product (PS) and longitudinal resistance distribution (LRD) as functions of perfusion rate in isolated rabbit lungs under zone II conditions (n = 10) and through the zone II-III ...

Recruiting Strategies for Potential 0+5 Vascular Residency Applicants

Annals of Vascular Surgery, 2012
The 0+5 integrated vascular residency training pathway was established in 2006 to allow for trainee-focused training culminating in vascular surgery certification only. An early concern was whether enough medical students could be recruited directly into a vascular internship without the exposure that a general surgery residency provides.

Repairing the vascular surgery workforce: attract, recruit and retain

Journal of Vascular Societies Great Britain & Ireland, 2023
Vascular surgery manages diseases of the arteries, veins and lymphatics, and with a growing and more aged population, both the prevalence and frequency of intervention for vascular disease is increasing.1–3 Healthcare in general, and vascular surgery in particular, is experiencing acute on chronic workforce shortages which threaten the delivery of ...

Pulmonary Capillary Recruitment and Extracapillary Vascular Tone

1998
Elucidating the mechanisms controlling capillary recruitment could improve our understanding of the mechanisms underlying various pharmacological and pathophysiological processes.

Contribution of resident and recruited macrophages in vascular physiology and pathology

Current Opinion in Hematology, 2018
Purpose of review Macrophages are generally believed to originate entirely from the bone marrow; however, this paradigm is challenged by the discovery of yolk-sac-derived resident macrophages. Here, we provide an overview of recent advances in the ontogeny and function of resident macrophages ...

Evidence that heterogeneity of cerebral blood flow does not involve vascular recruitment

American Journal of Physiology-Heart and Circulatory Physiology, 1993
Recent studies indicate that blood flow to cerebral cortex is not homogeneous but may vary both spatially and temporally. In addition, some investigators have reported that capillaries and arterioles can be recruited to increase cerebral blood flow, an issue that is extremely controversial.

Early recruitment of phagocytes contributes to the vascular inflammation of giant cell arteritis

The Journal of Pathology, 2004
AbstractVascular inflammation in giant cell arteritis is generally described as a process involving dendritic cells, T‐lymphocytes, and effector tissue macrophages. Less is known about the contribution of phagocytes that are recruited early, such as monocytes and neutrophils. These cells express and secrete pro‐inflammatory S100 proteins which directly

Connexin 40 is dispensable for vascular renin cell recruitment but is indispensable for vascular baroreceptor control of renin secretion

Pflügers Archiv - European Journal of Physiology, 2014
Defects of the gap junction protein connexin 40 (Cx40) in renin-secreting cells (RSCs) of the kidney lead to a shift of the localization of RSCs from the media layer of afferent arterioles to the periglomerular interstitium. The dislocation of RSCs goes in parallel with elevated plasma renin levels, impaired pressure control of renin secretion, and ...
