Spinal cord regeneration deploys cell-type specific developmental and non-developmental strategies to restore neuron diversity

Avery Angell Swearer, Samuel Perkowski, Iba Husain…·Andrea Elizabeth Wills

The paper compares neuron diversity and regeneration strategies in developing and regenerating spinal cords of Xenopus tropicalis using single-cell gene expression.

Shh signaling directs dorsal ventral patterning in the regenerating X. tropicalis spinal cord

Avery Angell Swearer, Samuel Perkowski, Andrea Elizabeth Wills

This study investigates the role of Shh signaling in establishing the dorsal-ventral axis during spinal cord regeneration in Xenopus tropicalis, finding that neural progenitor domains are more sensitive to Shh perturbation during regeneration than in uninjured tissue.
