OBJECTIVE To assess the role of oxygen in normal retinal vasculogenesis. METHODS A new preparation for studying cytogenesis in retinal wholemounts was developed. Nuclei of dividing cells were labeled with a monoclonal antibody to bromodeoxyuridine (BrdU), and vascular cells were covisualized with

OBJECTIVE To study the synergistic effects of hypothermia and hypoxia on the damage of pulmonary microvascular endothelial cells (PMVEC) in rat. METHODS Primary PMVECs were obtained by complex phosphoesterasum digesting from isolated lung tissues of Wistar rats, the PMVECs were identified by phase

Hypoxia stimulates angiogenesis in some microvascular beds, but no clear angiogenic effect of hypoxia has yet been demonstrated in adult skeletal muscle. In this study the distribution of alkaline phosphatase (APase) was compared with a novel microvascular marker, Griffonia simplicifolia I (GSI), to

Animals native to high altitude must overcome the constraining effects of hypoxia on tissue O2 supply to support routine metabolism, thermoregulation in the cold, and exercise. Deer mice (Peromyscus maniculatus) native to high altitude have evolved an enhanced aerobic capacity in hypoxia, along with

Exposure to hypoxia alters many aspects of endothelial cell metabolism and function; however, changes in surface glycoconjugates under these conditions have not been extensively evaluated. In the current studies, we examined surface glycoproteins of cultured bovine aortic (BAEC) and pulmonary

Spinal nerves and their associated dorsal root ganglion (DRG) cells can be subject to mechanical deformation and hypoxia associated with pathology such as disc herniation, spinal stenosis and spine trauma. There is very limited information on the response of adult DRG neurons to such stressors. In

Pulmonary arterial hypertension (PAH) is a lethal disease characterized by elevations in pulmonary arterial pressure, in part due to formation of occlusive lesions in the distal arterioles of the lung. These complex lesions may comprise multiple cell types, including endothelial cells (ECs). To

OBJECTIVE Retinal detachment induces neural and photoreceptor cell degeneration and fast activation of micro- (immune) and macroglial cells. Hypoxia caused by increased distance between the choriocapillaris and the neural retina, and retinal oedema during detachment, are factors causing gliotic

Diabetes, apart from generalized neuropathy and microangiopathy, involves tissue hypoxia, which may drive chronic proinflammatory state. However, studies on the ventilatory control in diabetes are sparse and conflicting. In this study we examined the function and morphology of diabetic carotid
