A ‘Cell-estial Bloom’ of human induced pluripotent stem cells (hiPSCs) flourishes on a micropatterned island. This image presents a colony of live hiPSCs, with fluorescently labeled Lamin B delineating the nuclear lamina within each cell.

This image presents a colony of live hiPSCs, with fluorescently labelled Lamin B delineating the nuclear lamina within each cell.

"Dancing actinotroch" by Allan Carrillo-Baltodano:
Actinotroch larva of a phoronid worm with phalloidin shown in yellow and acetylated tubulin in magenta. Imaged with a Zeiss LSM 800 at 10 x magnification.

"Who’s active?" by Julia Peloggia de Castro:
The image depicts a zebrafish embryo at 9 hours post-fertilisation on a lateral view. Cells are stained with MitoTracker, which labels active mitochondria, and cell membranes are labelled in cyan with a EGFP transgenic membrane tag. Image was taken using a 20x objective on a spinning disk confocal microscope.
