By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.

Blood flow-driven shear forces guide the sequential signaling of two antagonistic paired receptors, a critical bi-facet step that first supports leukocyte docking, then initiates transmigration through endothelium.

Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

Two-photon phosphorescence lifetime microscopy reveals the physiological values of oxygen concentration and blood flow parameters in the brains of awake mice.

Extracellular matrix signaling constitutively regulates cerebral blood flow in both physiological and pathological settings.

Brain temperature and oxygenation vary according to the imaging conditions during two-photon microscopy.

Emergence of hematopoietic stem cells from an aortic component is a unique phenomenon of cell extrusion, with no equivalent in cell biology, and which is adapted to environmental constraints exerted by endothelial cells and hemodynamics forces.

A threshold level of blood flow initiates developmental blood vessel regression; this threshold can be regulated by non-canonical Wnt ligands.

T cell progenitor homing into the thymus requires kindlin-3 to stabilize their adhesion to vascular integrin ligands when blood flow velocities and shear rates increase during development.

Gestational age estimation models derived from newborn screening bloodspot samples are effective on data obtained from both heel prick and cord blood samples in low-resource settings.
