Medaka fish were able to use faces for individual recognition, and were slower to recognise inverted faces but not inverted non-face shapes.

The unfolded protein response sensor/transducer IRE1-mediated splicing of XBP1 mRNA encoding its active downstream transcription factor to maintain the homeostasis of the endoplasmic reticulum is sufficient for growth and development of medaka fish.

The 5' modification of the donor template facilitates highly efficient Crispr targeted homologous recombination and at the same time favors single copy integration.

3D niche topology imposes a spatially biased random stem cell loss, which is differentially fine-tuned in neural retina and retinal pigmented epithelium to regulate growth, shape, and cellular topology.

Timely macrophage recruitment is essential for neovascularization and neutrophil clearance during cardiac regeneration.

Müller glia cells in the medaka (Oryzias latipes) retina act as lineage restricted progenitors which only regenerate photoreceptors but can be activated to perform as potent stem cells using Sox2.

Studies of medaka and other ricefishes in the wild could provide insights in fields such as evolutionary biology, development and cancer research.

The fish gill, an ever-growing organ with fast turnover rate, displays dedicated stem-cell populations for growth and homeostasis that are interchangeable upon external challenges.

In medaka fish, galanin-expressing neurons in the medial preoptic area occur nearly exclusively in males and mediate androgen-dependent male–male aggressive chases.

A physical niche for neural stem cells is generated by the induction of the immediate skin epithelium, a process triggered by the arrival of neural precursors during sensory organ formation in medaka.
