Tail regeneration in lungfish provides insight into evolution of limb regrowth

A new study published in the Proceedings of the Royal Society B from researchers at the University of Chicago and Universidade Federal do Pará explores regenerative ability in the tails of West African lungfish for the first time, and finds that the process shares many of the same traits as tail regeneration in salamanders. Their results indicate that this trait was likely found in a common ancestor – and provide a new opportunity for better understanding and harnessing the mechanisms of limb regrowth.

PECASE Honoree Sohini Ramachandran Studies the Genetic Foundations of Traits in Diverse Populations

NIGMS grantee and presidential award recipient Sohini Ramachandran, Ph.D., is challenging our understanding of genetic variation among human populations. She discusses her research on how the genetic composition of traits and diseases varies among populations, the value of statistical and computational work in human genetics, and what this all means for patient treatment.
