  • Support of imaging of microglia and neurons

Why use zebrafish model ?

Zebrafish (Danio rerio) has become a powerful and versatile animal model for translational research on human neurological disorders. Beyond of its remarkable optical transparency, this small vertebrate exhibit a profound resemblance with the human brain. Their relatively simple nervous system permit real-time neurological imaging, and Ca2 imaging. The zebrafish embryos are quite malleable to genetic manipulation by morpholino antisense oligonucleotide, mRNAs, transgenes and genome editing techniques like CRISPR-Cas9, and TALENs technologies.
