Lovely work by @martinestermann.bsky.social and colleagues from the Capel lab! Together with our recent work (www.biorxiv.org/content/10.1...), this really makes a strong case that lactate is crucial to supporting male germ cells in vivo - from flies to mammals.

Excited to share the preprint that marks the beginning of my journey into the world of metabolism! 🍭🧬
A new chapter exploring how metabolic pathways shape gonadal development.
There’s more to come, stay tuned!
