Noyaux de cellules et cytosquelette d’actine d’une patte de drosophile

Cell nuclei and actin cytoskeleton in the developing leg of a fruit fly, observed using a confocal microscope. The nuclei envelopes are visible in green, while the actin cytoskeleton is marked in red. Research scientist are testing the role of the nucleus in generating the force exercised by dying cells. This force contributes to the formation of folds, which are the origin of the future joints. More generally, the scientists aim to understand how programmed cell death or apoptosis can influence how tissues change shape.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
