There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Owing to their ability to self-renew indefinitely and differentiate into any cell type in the body, human pluripotent stem cells (hPSCs) represent a transformative platform for applications such as drug toxicity testing and regenerative medicine. Moreover, the advent of induced pluripotent stem cell (iPSC) technologies may revolutionize disease treatment strategies by providing unlimited material for studying disease mechanisms and screening potential therapeutics in vitro. However, for these applications to reach fruition, hPSC-derived progeny must possess phenotypes that accurately represent endogenous human tissues. With this consideration in mind, I will outline several strategies for modeling neurovascular systems with hPSCs. First, I will detail a novel approach for generating endothelial cells with properties of the blood-brain barrier (BBB), a highly specialized vascular interface that maintains central nervous system (CNS) health and homeostasis but restricts the delivery of therapeutics to diseased tissue. I will also describe completely defined, xeno-free methods for differentiating hPSCs into neural cells from defined anatomical locations in the hindbrain and spinal cord, which will enable new avenues for examining neurodegenerative disease. I will conclude by briefly discussing how these hPSC platforms, in conjunction with microscale engineering techniques and synthetic biology approaches, could facilitate innovative studies of brain drug uptake and disease mechanisms outside of the human body.
