Sox9 and Rbpj differentially regulate endothelial to mesenchymal transition and wound scarring in murine endovascular progenitors.

Nat Commun 2021 May 7;12(1):2564. Epub 2021 May 7.

The University of Queensland Diamantina Institute, The University of Queensland, Woolloongabba, QLD, Australia.

Endothelial to mesenchymal transition (EndMT) is a leading cause of fibrosis and disease, however its mechanism has yet to be elucidated. The endothelium possesses a profound regenerative capacity to adapt and reorganize that is attributed to a population of vessel-resident endovascular progenitors (EVP) governing an endothelial hierarchy. Here, using fate analysis, we show that two transcription factors SOX9 and RBPJ specifically affect the murine EVP numbers and regulate lineage specification. Read More

Neurovascular-modulation: A review of primary vascular responses to transcranial electrical stimulation as a mechanism of action.

Brain Stimul 2021 May 4. Epub 2021 May 4.

Department of Biomedical Engineering, The City College of New York (CCNY), New York, NY, USA.

Background: The ubiquitous vascular response to transcranial electrical stimulation (tES) has been attributed to the secondary effect of neuronal activity forming the classic neurovascular coupling. However, the current density delivered transcranially concentrates in: A) the cerebrospinal fluid of subarachnoid space where cerebral vasculature resides after reaching the dural and pial surfaces and B) across the blood-brain-barrier after reaching the brain parenchyma. Therefore, it is anticipated that tES has a primary vascular influence. Read More
