Title: Spiral of inhibitory neurons
Microscope: Confocal Zeiss LSM700
Description: Here shown is an organotypic hippocampal slice of a mouse brain, which was kept in culture for over 2 weeks before fixation. Labelled in blue are all cell bodies (DAPI), to show the outer contours of the slice. In green is the genetic labelling of GAD65-GFP, indicating a subset of inhibitory neurons that express this protein.

Title: My heart beats for science
Microscope: Spinning Disc 1 Nikon-Roper ILAS PhotoAblation (Kruyt building)
Description: This is a compilation of pictures to form a heart shape. The pictures show a zoom of a human induced-pluripotent stem cell-derived cardiomyocyte, which was transduced with lentiviral vectors to express a GFP-tagged microtubule plus-end marker (end-binding protein 3 (EB3)) and tagRFP-LifeAct; an actin marker. In cardiac cells the actin cytoskeleton forms contractile units named sarcomeres, which allow the cell to beat.
