초록

Difficulties with poor reproducibility and translatability of animal model-based research, along with increased efforts to abide by the 3Rs tenet of animal welfare, are driving demand for more relevant human cellular systems. This is especially true for central nervous system (CNS) vasculatures with specialized properties and barriers, namely the blood-brain and blood-retinal barriers (BBB and BRB, respectively) which are difficult to model in vitro. The BBB and BRB protect neurovascular units by regulating nutrient homeostasis, maintaining local ion levels, protecting against exposure from circulating toxins and pathogens, and restricting passage of peripheral immune factors. In this manuscript, we will describe transgenic and pharmacological-based protocols to generate relevant BBB and BRB models both from human pluripotent stem cell-derived endothelial cells (hPSC-ECs) and from primary human umbilical vein endothelial cells (HUVECs). When followed, researchers can expect to generate well-characterized, anatomical and functional BBB and BRB EC monolayers in 36-48 h that are stable up to 90 h. The ability to generate more relevant BBB and BRB EC cultures will improve drug discovery efforts and inform future therapies for neurovascular disorders.
