The Stem Cell Report with Janet Rossant
Stem cell science has catapulted to the forefront of biomedical research over the last decade, bringing with it the potential to transform human health and the treatment of devastating diseases and disorders. Janet Rossant, an internationally recognized stem cell pioneer and the dynamic editor-in-chief of Stem Cell Reports, explores basic discoveries in stem cell research and its application. Dr. Rossant goes “beyond the paper,” bringing authors together to draw new insights and explore the questions and creativity that drive new breakthroughs. Stem Cell Reports, published by the International Society for Stem Cell Research (ISSCR), is an open-access, peer reviewed journal that supports the field of stem cell research and regenerative medicine.

Crossing the Border: Modeling the Blood Brain Barrier
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 barrier. Our guests today developed a blood-brain model using induced pluripotent stem cells (iPSCs)-derived endothelial cells with brain-specific identity. Using this model they were able to investigate how disease risk factors affect intracellular transport and reveal a new role for ApoE4 in the regulation of iron metabolism at the blood-brain barrier.
