Modeling Pediatric Brain And Central Nervous System Cancer In Zebrafish, Staci Lyn Solin Jan 2015

Modeling Pediatric Brain And Central Nervous System Cancer In Zebrafish, Staci Lyn Solin

Graduate Theses and Dissertations

Brain and central nervous system (CNS) cancers are the leading cause of cancer-related death in children (Ostrom QT et al., 2015). Low-grade brain and CNS tumors that require minimal surgical resection due to their location in critical regions are associated with long-term morbidity throughout the life of the child (Armstrong GT et al., 2011). Children diagnosed with high-grade, aggressive brain and CNS tumors generally have a poor outcome and suffer significant deficits in neurological and neuroendocrine function as a result of intensive therapy (Fangusaro J et al., 2012). Effective, targeted therapeutics for the treatment of pediatric brain and CNS cancer ...

Endothelial tubulogenesis is a crucial step in the formation of functional blood vessels during angiogenesis and vasculogenesis. Here, we use in vivo imaging of living zebrafish embryos expressing fluorescent fusion proteins of β-Actin, α-Catenin, and the ERM family member Moesin1 (Moesin a), to define a novel cord hollowing process that occurs during the initial stages of tubulogenesis in intersegmental vessels (ISVs) in the embryo. We show that the primary lumen elongates along cell junctions between at least two endothelial cells during embryonic angiogenesis. Moesin1-EGFP is enriched around structures that resemble intracellular vacuoles, which fuse with the luminal membrane during expansion ...
