The blood-brain barrier (BBB), formed by brain endothelial cells, pericytes, and astrocytes, is organized into a neurovascular unit that regulates the exchange of proteins between blood circulation and brain parenchyma. Human stem-cell-based models using brain endothelial cells are a powerful tool to investigate how disease-related conditions might affect the blood-brain barrier integrity. However, the cell type composition is critical to faithfully model transcytosis across the blood-brain b...

Don’t Dull the SPARCL: The Lung Microvasculature and its Role in Development
The mature lung in both humans and mice is highly vascularized, with approximately 30% of all cells being endothelial cells (ECs). The blood vessels have a physiological role in gas exchange within the tissue, but the vascular cells have additional role(s) beyond supplying oxygen and nutrients to the tissue. For example, the adult lung endothelium responds to injury by activating pathways for alveolar re epithelialization and during embryonic development, disrupting vascularization ex v...
