Immortal Planarians: Better Stem Cells under Starvation

Planarians are very plastic animals. Due to a high number of stem cells, planarians are able to regenerate a new individual from a tiny fragment of their body. Researchers of the Leibniz Institute on Aging (FLI) in Jena, Germany together with colleagues of the Spanish National Center for Cardiovascular Research in Madrid, Spain now investigated the planarian stem cell pool under conditions of starvation. Their results show that long telomeres are a major characteristic of adult stem cells in planarians. Starvation has a positive effect on the adult stem cell pool, as starved stem cells show a higher telomere length. The results are now published in the Journal Stem Cell Reports.
