Immune regulation of neuronal stem cells in the medaka retina

Rashi Agarwal, Joergen Benjaminsen, Katharina Lust, Clara Julseth, Natalia Fuchs, Eva Hasel de Carvalho, Fanny Eggeler, Omnia El Said Ibrahim, Narges Aghaallaei, Baubak Bajoghli, Joachim Wittbrodt

The paper shows microglia phagocytose medaka retinal stem cells under homeostasis, but Ccl25b-Ccr9a signaling is not essential for their maintenance.

Quantitative mapping of heterochrony to species-specific phenotypes

Jess J Bourn, Simon Knoblich, Sophie Kneeshaw, Joergen Benjaminsen, Lucie Žílová, Alexander Aulehla, Lauren M. Saunders, Joachim Wittbrodt, Ewan Birney, Michael W. Dorrity

The paper maps heterochrony in zebrafish and medaka using single-cell genomics, revealing cell-level timing shifts that contribute to species-specific phenotypes.
