3D optogenetic control of arteriole diameter in vivo

eLife, 2022
Modulation of brain arteriole diameter is critical for maintaining cerebral blood pressure and controlling regional hyperemia during neural activity. However, studies of hemodynamic function in health and disease have lacked a method to control arteriole

Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age [PDF]

, 2018
Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply.

Brain Tumor Vascular Network Segmentation from Micro-Tomography [PDF]

, 2011
Micro-tomography produces high resolution images of bio- logical structures such as vascular networks. In this paper, we present a new approach for segmenting vascular network into pathological and normal regions from considering their micro-vessel 3D ...

Vascular Development [PDF]

Arteriosclerosis, Thrombosis, and Vascular Biology, 2018
The vascular system forms as a branching network of endothelial cells that acquire identity as arterial, venous, hemogenic, or lymphatic. Endothelial specification depends on gene targets transcribed by Ets domain–containing factors, including Ets variant gene 2 (Etv2), together with the activity of chromatin-remodeling complexes ...
