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.

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

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.

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.

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.

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.

A shift in antero-posterior positional information may contribute to the fin-to-limb transformation.

Zebrafish scales depend on interactions among Wnt, Ectodysplasin and Hedgehog signaling pathways similar to those underlying feathers, teeth and hair follicles, suggesting a deep homology of ectodermal appendages in vertebrates.
