Imaging spotlight: U-ExM atlas of microbial eukaryotes

Posted by , on 20 January 2026

In this paper highlight from Hiral Shah and colleagues, we learn about their ultrastructure expansion microscopy (U-ExM) atlas of over 200 cultured planktonic eukaryotes. This post includes technical advice for ExM users and highlights the open-access resource that they have generated for cytoskeleton or marine microorganism aficionados (and microscopy sciart lovers!)

Cytoneme Imaging Tips and Tricks

Posted by , on 19 January 2026

There has been a growing interest in visualizing long and thin membrane extensions. The field of intercellular connections has exploded, with elegant bioimaging studies focusing on structures like cytonemes, tunneling nanotubes (TNTs), intercellular/cytokinetic bridges (IB/CBs), and migrasomes. This enhanced interest in the intercellular communication facilitated by these extensions is largely due to the recent technological

Invitation to follow the LCI microscopy course on Zoom

Posted by , on 24 January 2024

It is my pleasure to invite you to follow the LCI facility microscopy course Microscopy: improve your imaging skills – from sample preparation to image analysis. The course starts next Monday (29 Jan) and runs until the 16th of February.As usual, all the course lectures are broadcasted live on Zoom. It is free of charge

Community collective: essential optimisation

Posted by , on 29 June 2023

Microscopy images have the ability to wow us, and the data we can extract from them can help answer our research questions, as well as leading us to pose new ones. Advances in sample preparation and microscopy technology means we have never been in a better position to use imaging in biology but is it

Affimers – small probes for big imaging experiments

Posted by , on 9 August 2022

Antibodies have been used to label proteins of interest since the 1970s. However, their large size (around 15 nm long for IgG) makes the penetration of dense structures within the cell a challenge and places the fluorophore away from the target protein. This latter issue, known as a ‘linkage error’, particularly impacts accuracy and precision

A new Review in Journal of Cell Science discusses how specimens can impact image acquisition

Posted by , on 13 April 2022

With the development of new imaging strategies and technologies and advanced computational analyses has come a body of literature addressing various aspects of optimising imaging and processing. However, the impact of the sample itself on the quality of the image attained has garnered less exploration. Fluorescent microscopy is dependant on two factors – the intensity

Imaging nuclear dynamics and chromatin organization in a live intact organism: the design of the minimal constraint device

Posted by , on 9 March 2022

To visualize the response of the nucleus and chromatin to mechanical signals, I developed a device that enables their imaging in a live intact Drosophila larva.   Together with genetically encoded fluorescent markers, we can track muscle contraction and nuclear dynamics, as shown in Movie 1.  While the muscle is at rest, we can image chromatin

Protein micropatterning: beauty standards in cell culture

Posted by , on 16 February 2022

When imaging cells grown on a flat substrate, such as a glass coverslip, we quickly admire the diversity of morphologies different cells can take on. Some cells, such as COS7, will take on a flat “pancake”-like shape, which makes it easy to image its organellar structure in a 2D plane. On the other hand, a

Asymmetric cell divisions in 3 dimension stem cell colonies

Posted by , on 27 September 2021

When looking at the development of a multicellular organism, for example a human, the first striking feature is the progressive increase in cell numbers due to successive divisions, from one single tiny cell 80 mm in diameter to a 3.5 kg ball of organised cells forming a new-born baby. The way cells divide, in particular
