Multimedia Series: Rejuvenation

Axolotls (Ambystoma mexicanum) are a critically endangered species of salamander. They are also highly regenerative. The latest story in our Unusual Labmates series explores these fascinating creatures, what Whitehead Institute researchers are hoping to discover by studying them, and why they are worth preserving in the wild.

First-of-its-kind study uses MERFISH to map the spatial pattern of how stem cells choose their fates during adult regeneration in flatworms.

Whitehead Institute Member Yukiko Yamashita and colleagues show that stem cells play a special role in maintaining ribosomal DNA, which they do by dividing asymmetrically.
