Decrease in VEGF expression induces intussusceptive vascular pruning
(University of Nairobi,, 2011)
OBJECTIVE:
The concept of vascular pruning, the "cuting-off" of vessels, is gaining importance due to expansion of angio-modulating therapies. The proangiogenic effects of vascular endothelial growth factor (VEGF) are ...

The pulmonary blood-gas barrier in the avian embryo: inauguration, development and refinement
(University of Nairobi,, 2011)
In vertebrates, efficient gas exchange depends primarily on establishment of a thin blood-gas barrier (BGB). The primordial air conduits of the developing avian lung are lined with a cuboidal epithelium that is ultimately ...
Escape mechanisms after antiangiogenic treatment, or why are the tumors growing again?
(University of Nairobi,, 2011)
Inhibitors of angiogenesis and radiation induce compensatory changes in the tumor vasculature both during and after cessation of treatment. In numerous preclinical studies, angiogenesis inhibitors were shown to be efficient ...
Pre-hatch lung development in the ostrich.
(University of Nairobi,, 2012)
We studied development of the ostrich lung using light microscopy as well as electron microscopy techniques. At E24, the lung comprised a few epithelial tubes, interspersed with abundant mesenchyme with scattered profiles ...
Spatial and functional relationships between air conduits and blood capillaries in the pulmonary gas exchange tissue of adult and developing chickens
(2011)
The documented data regarding the three-dimensional structure of the air capillaries (ACs), the ultimate sites of gas exchange in the avian lung is contradictory. Further, the mode of gas exchange, described as cross-current ...
Parabronchial angioarchitecture in developing and adult chickens.
(University of Nairobi,, 2009)
The avian lung has a highly sophisticated morphology with a complex vascular system. Extant data regarding avian pulmonary angioarchitecture are few and contradictory. We used corrosion casting techniques, light microscopy, ...
Epithelial transformations in the establishment of the blood–gas barrier in the developing chick embryo lung
(Wiley, 2006)
The tall epithelium of the developing chick embryo lung is converted to a squamous one, which participates in formation of the thin blood–gas barrier. We show that this conversion occurred through processes resembling ...
Microvascular endowment in the developing chicken embryo lung
(The American Physiological Society, 2007)
In the current study, the contribution of the major angiogenic mechanisms, sprouting and intussusception, to vascular development in the avian lung has been demonstrated. Sprouting guides the emerging vessels to form the ...
