🧵6/6 Huge thanks to all co-authors and collaborators who made this possible! 🙌 We hope this protocol will be useful for researchers studying gonad development, reproductive biology, sex differentiation, embryonic organ culture, and developmental perturbations. #DevBio #ReproBio

🧵5/6 Although this protocol was tested in mice, we would love to see whether similar 3D-printed culture platforms can be adapted to other species. 🐸🐣🦎 Comparative gonad culture could open exciting ways to study conserved and species-specific mechanisms of sex differentiation.

Martín Estermann @martinestermann.bsky.social · 11/06/2026

🧵3/6 Fetal gonads are tiny, delicate, and develop fast. 🔬⏱️ A reliable culture system is essential not only to maintain gonads ex vivo, but also to perturb their development with chemicals, inhibitors, metabolites, or other treatments and ask how testis and ovary development change 🧪

110

Martín Estermann @martinestermann.bsky.social · 11/06/2026

🧵2/6 A key feature of this protocol is accessibility: the molds are 3D printable, and the files can be downloaded directly from the paper 🖨️🧫 We hope this makes fetal gonad culture easier to reproduce and adapt across labs.

Glycogen and lactate metabolism in mouse fetal Sertoli cells sustain the germ line

Estermann and Sheheen et al. identified a metabolic coupling between fetal Sertoli and germ cells in mice, driven by glycogen breakdown and lactate transport through the MCT4/MCT1 shuttle. This intera...

Martín Estermann @martinestermann.bsky.social · 11/03/2026

6/ This reveals a metabolic coupling between Sertoli cells and germ cells in the fetal testis. Sertoli cells break down glycogen → lactate, which is then transported 🚀 to support germ cell survival.

110

Martín Estermann @martinestermann.bsky.social · 11/03/2026

5/ We then tested the lactate shuttle 🚀. Sertoli cells export lactate through MCT4, which can be imported by germ cells via MCT1. Blocking this transport phenocopied the glycogen loss: germ cells were reduced ⬇️

110

Martín Estermann @martinestermann.bsky.social · 11/03/2026

4/ When glycogen metabolism was disrupted: • Testicular lactate levels dropped • Germ cell numbers decreased ⬇️ This suggested that glycogen in Sertoli cells might be used to support germ cells metabolically.

110

Martín Estermann @martinestermann.bsky.social · 11/03/2026

3/ We tested whether glycogen 🍬is required for Sertoli cell differentiation. Surprisingly: ❌ Blocking glycogen synthesis does NOT prevent Sertoli cell fate. So glycogen isn’t needed to specify Sertoli cells. But something else was happening…

110

Martín Estermann @martinestermann.bsky.social · 11/03/2026

2/ One intriguing observation in mouse embryos 🐭 During sex determination, Sertoli cells accumulate large glycogen stores 🍬 Only between E11.5-E13.5 ⏱️ So… what is this glycogen doing?

110

Martín Estermann @martinestermann.bsky.social · 11/03/2026

1/ Metabolism is increasingly recognized as a driver of developmental processes ⚙️ But during gonadal differentiation, we still know surprisingly little about how metabolic pathways influence cell differentiation and survival.

110

Martín Estermann @martinestermann.bsky.social · 11/03/2026

🚨New paper out in Cell Reports ‼️ www.cell.com/cell-reports... Why do fetal Sertoli cells store glycogen 🍬 during testis development? It turns out they are feeding germ cells. We discovered a previously unrecognized metabolic coupling between Sertoli cells and germ cells in the fetal testis 🧵
