Humans are able to detect fitness decay in colleagues by looking at the graying of the hair or the wrinkles in their faces. Work from my laboratory in the last few years has shown that cells can also detect fitness levels of neighboring cells using a molecular code. Those “fitness fingerprints” (Rhiner et al., Dev.Cell, 2010; Merino et al., Curr. Biol., 2013) can be used to mediate cell selection by recognizing and eliminating less fit cells during ageing (Merino et al., Cell, 2015), regeneration (Moreno et al., Curr. Biol., 2015) and cancer (Levayer et al., Nature 2015).

Cell Fitness 
Moreno Lab eduardo.moreno@research.fchampalimaud.org
Overview
We are generally interested in how cells of multicellular animals can detect the fitness of neighboring cells selecting the fittest cells. This is a fundamental process that has implications in several broader fields, for example:
1. Ageing
During ageing, elimination of unfit cells maintains tissue health and prolongs lifespan (Merino et al., Cell 2015).
2. Cancer
Tumor cells can behave as superfit cells and expand by killing and replacing neighbouring tissue, leading to tissue invasion and destruction (Levayer et al., Nature 2015).
3. Neurobiology
Neurons can also exchange fitness information leading to the culling of less fit neurons during development (Merino et al.Curr. Biol., 2013), brain regeneration (Moreno et al., Curr. Biol., 2015) and brain ageing (Merino et al., Cell 2015).
