Featured image with Rossana Melo

Posted by , on 16 February 2024

Our featured image, acquired by Rossana Melo, shows a human eosinophil isolated from the peripheral blood using a negative immunomagnetic selection method and prepared for transmission electron microscopy (TEM). The image was acquired with a Tecnai G2 Spirit Bio Twin ThermoFisher Scientific (former FEI) electron microscope.

Our featured image was acquired by Virginia Barrera and was the winning image from the Institute of Molecular and Cellular Biology of Rosario (IBR-CONICET) annual retreat. It depicts a transversal cut of a soybean, with Calcofluor White staining cellulose and Basic Fuchsine labelling lignin.

Featured images in 2023

Posted by , on 5 January 2024

In 2023, we started a featured image series and we have been delighted to highlight the microscopists that acquired these beautiful images! You can check out the full series here and in the gallery below. We are continuing the series in 2024 and would love to have nominations, including self-nominations. Send us an email at

Our featured image shows a culture of boa constrictor kidney cells that have been transfected with a fusogenic viral protein. This leads to the formation of giant multi-nucleated cells. The cells were transfected with the fusogenic viral protein (shown in gold), left several days for efficient protein expression and for cell fusion to occur, plated

Our featured image shows a single human dopaminergic neuron generated from a human stem cell, acquired via super-resolution Airyscan confocal microscopy at the University of Oxford Micron facility by Nick Gatford. We caught up with Nick to find out about his research and what he is excited about in microscopy.

Our featured image, acquired by Oona Paavolainen, shows a primary mammary gland organoid, in a collagen-I matrix, formed from a single primary epithelial cell isolated from material obtained from a breast reduction surgery. The image was taken with a spinning disk confocal microscope (3i CSU-W1 Spinning disk) using a 20x Zeiss Plan-Apochromat (NA=0.8) objective. The

Our featured image, acquired by Till Stephan, shows a live-cell stimulated emission depletion (STED) microscopy recording of a HeLa cell in which mitochondria (orange-magenta) and microtubules (cyan) are labelled. The super-resolution image reveals the densely stacked mitochondrial cristae, coordinated invaginations of the mitochondrial inner membrane.

New look for FocalPlane

Posted by , on 13 November 2023

We are delighted to launch a new look for FocalPlane. Every day this week, we’ll be releasing a new banner image and highlighting the scientist that acquired it. Today, we start with an image from Rebecca Simkin. Rebecca won our 2023 image competition, and you can read our featured image post with Rebecca here: https://focalplane.biologists.com/2023/09/01/and-the-winner-is/

Featured image with Ioakeim (Makis) Ampartzidis

Posted by , on 27 October 2023

Our featured image, ‘Dandelion in spring’ from Ioakeim (Makis) Ampartzidis, shows neuroepithelial-like cells cultured on glass beads. The cell nuclei are coloured in magenta, and the cytoskeleton is stained in black, labelling F-actin. The actively proliferating cells are highlighted with Ki-67 antigen in green. We caught up with Makis to find out more about his
