Zebrafish

Zebrafish (Danio rerio) is a small freshwater fish that is an extensively studied vertebrate model organism. It can be bred rapidly in large numbers, is amenable to genetics, and has a clear embryo, making it attractive to study vertebrate development, physiology and disease.

    Optogenetic and thermogenetic tools have been limited to applications for single-state control of cellular processes. A single-component optogenetic tool was found to act as both a temperature sensor and a photoreceptor, enabling multi-state control of developmental signaling.

    How lymphatic vessels arise from veins is still poorly understood. A study reports the discovery of a ribosome biogenesis regulator Ddx21 as a previously unappreciated specific factor that is important for the first steps of lymphatic but not blood vessel development. The finding may lead to better strategies to selectively target lymphangiogenesis.

    A new CRISPR/Cas9 method that can generate F0 mutant zebrafish has the potential to cut costs, spare time, and reduce animal use for researchers interested in screening loss-of-function alleles in vivo.

    To achieve knockdown rather than knockout of particular genes, a new paper demonstrates a CRISPR/Cas13 method that can efficiently edit mRNA in zebrafish, medaka, killifish, and mouse embryos.
