Excited to share @rbrianroome.bsky.social ‘s beautiful paper on development of the dorsal horn of the mouse spinal cord @science.org

This is how the anatomical organization and cell types that process pain, touch, body position and more are laid down.

Ontogeny of the spinal cord dorsal horn
The dorsal horn of the mammalian spinal cord is organized into laminae where each layer is populated by different neuron types, has distinctive circuit connections, and plays specialized roles in beha...

Good to see the peer reviewed version of this published

A chemo-optogenetic system for spatiotemporal control of gene expression

We use it to:

- Reconstruct SHH mediated neural tube patterning in vitro

- Measure extracellular half-life of Shh

How do pleiotropic TFs generate organized diversity in developing tissues? @spinalorga.bsky.social shows that PAX3 & PAX7 organize #SpinalCord by acting as both repressors & pioneer activators, regulated by #morphogens to ensure precise neural subtype specification @plosbiology.org 🧪 plos.io/4qumsla

First preprint from the lab!

Expression of 3 TFs - Onecut2, Pou2f2 and Pou3f1 - in sequentially generated neurons correlates with and is functionally required for the correct specification of neuronal subtypes mediating spinal sensory and motor output!
