Diverse Engraftment Capability of Neuroblastoma Cell Lines in Zebrafish Larvae.

ABSTRACT: Xenotransplantation of neuroblastoma cells into larval zebrafish allows the characterization of their in vivo tumorigenic abilities and high-throughput treatment screening. This established preclinical model traditionally relies on microinjection into the yolk or perivitelline space, leaving the engraftment ability of cells at the hindbrain ventricle (HBV) and pericardial space (PCS), sites valuable for evaluating metastasis, angiogenesis, and the brain microenvironment, unknown. To address this gap in knowledge, Casper zebrafish at 48 h postfertilization were microinjected with approximately 200 Kelly, Be(2)-C, SK-N-AS, or SY5Y cells into either the HBV or PCS. Fish were imaged at 1, 3, and 6 days postinjection and tumor growth was monitored at each timepoint. We hypothesized that
