Winners of the Huygens Image Contest


As in past years, we've received many high quality images and movies for the ''Huygens Image Contest", and our job to select the winners was a challenging one. We like to thank all the participants for submitting their images for this contest.

After careful consideration, we made the decision to award the first prize of the 2018 contest to Dr. Outi Paloheimo from the Tampere Imaging Facility, University of Tampere, Finland. Mrs. Outi Paloheimo submitted a Huygens deconvolved Zeiss LSM780 confocal image of high quality that is Christmas card ready material. The image, which is displayed below and will appear on our 2018 Christmas card, represents Human induced pluripotent stem cell derived cardiomyocytes (heart cells) showing filamentous actin and nuclei. We congratulate Outi with winning an ASUS Chromebook.
All other participants of the 2018 contest received a bluetooth speaker for listening to their favorite Christmas music.

An overview of all the winners of the Huygens Image Contest in recent years can be found below. A big thanks to the participants for making the Huygens Image Contest into a great success and we hope you will join the next years Huygens Image Contest. Images and movies for contests can be submitted all year through, see also this years contest.

Calbindin immunoreactivity in the ganglion cell layer of a mouse retina. The image was taken close to the center of the retina, where the ganglion cell axons gather in thick bundles and then leave the eye as the optic nerve. This confocal stack was recorded on a Leica SP8 microscope, deconvolved using Huygens Essential, and finally color-coded for depth.

Huygens deconvolved and MIP rendered confocal image (Nikon; NA 0.45) of a tadpole intestine with nuclei in orange and muscle actin in cyan. The direction of the gut looping can be used as a readout for proper asymmetric organ development. Looping in the other direction is a sign of perturbed Nodal/Notch signaling.

Huygens deconvolved and MIP rendered epifluorescence Z stack of part of a mouse brain. The image shows aquaporin 4 (red) as individual astrocytic end-feet along a blood vessel. Thanks to deconvolution, GFAP (green) can be colocalized with AQ4 in small areas, but the end-feet and arms of astrocytes can be identified as distinguishable structures in terms of protein expression.
