Body part #regeneration appears to be a whole-body affair.

#Planaria are freshwater #flatworms that have become a key model for studying #regeneration and #stem #cells, as they can regenerate any part of the body, even the head. But how does the animal know what part of its body is missing and what kind of tissue it needs to #regenerate?

'Why some animals can regenerate while many others cannot remains a fascinating question. Even amongst planarian flatworms, well-known for their ability to regenerate complete animals from small body fragments, species exist that have restricted regeneration abilities or are entirely regeneration incompetent. Towards the goal of probing the evolutionary dynamics of regeneration, we have assembled a diverse live collection of planarian species from around the world.'
