EMBO Practical Course

Ultrastructure expansion microscopy: from cells to tissue

Overview

Course overview

Expansion microscopy (ExM) physically magnifies specimens, allowing to obtain super-resolution images using a conventional diffraction-limited microscope such as confocal microscopy. This powerful technique is easy to implement but it requires some hands-on training. The gain in resolution can be further enhanced with the use of super-resolution microscopes such as STED. This course centered on the Ultrastructure Expansion Microscopy (U-ExM) based techniques applied to mammalian cells aims at disseminating and discussing expansion microscopy protocols and is intended for cell biologists, parasitologists, etc, with applications ranging from tissue to cells.

Audience

This course is intended for researchers ranging from PhD students to post-docs and senior scientists as well as staff from bioimaging platforms who wish to establish expansion microscopy in their respective institutes.

Modules/resources

  • U-ExM in cells
  • U-ExM in tissue
  • U-ExM in cryo-sections

Learning outcomes

After this course you should be able to:

  • Apply ultrastructure expansion microscopy on your own samples once back in your laboratory (sample preparation and imaging). Note that depending on your sample, the preparation might slightly differ.
  • Spread the technique to your colleagues in their respective laboratories
  • Choose the most appropriate expansion microscopy protocols for your needs

What past participants say about the course

“I attended the EMBO Practical Course on Ultrastructure Expansion Microscopy in 2024, and it was fantastic. The course was extremely well-organized, striking a perfect balance between theoretical and practical sessions. The scientific organizers and trainers were top-notch scientists capable of addressing any scientific questions. Additionally, the course organizers were fantastic in supporting participants in all aspects. I highly recommend it!” – Francesco Consolato, San Raffaele Scientific Institute, Italy

“Attending this course was an incredible experience. It allowed me to acquire practical skills in the use of U-ExM and provided me with valuable insights for applying this technique in my institute.” – Celina Terán Ramírez, National Autonomous University of Mexico, Mexico

Financial assistance

Financial assistance

Limited financial assistance is provided by the EMBL Advanced Training Centre Corporate Partnership Programme and EMBO in the form of  travel grants and childcare grants

Your place in the meeting is only confirmed by paying the registration fee, which is mandatory even when receiving a fee waiver.

Travel grant

The travel grant will cover the cost of travel (airfare, train, bus, taxi, and visa) and/or registration fees and is provided up to specified caps which are normally as follows:

– up to €500 for any participant travelling to an EMBO Practical Course.

– up to €1000 for any participant working in Chile, India, Singapore or Taiwan travelling to an EMBO Practical Course.

The organisers may reduce the grant cap to accommodate more participants. Recipients will be notified of their travel cap amount when they are informed of the outcome of their application.

Only submissions for financial assistance will be accepted. Presentation abstracts cannot be submitted here and will be declined. 

In your application you will be asked to summarise your current work,  answer questions regarding why your lab cannot fund your attendance, and how your attendance will make a difference to your career. Application for financial support will not affect the outcome of your registration application.

*For some events, applications for Childcare Grants will still be done by email. Information about the grant will be sent out shortly after the abstract/motivation letter deadline. Please contact the event Conference Officer if you have any questions.

Selection

A selection process will take place with the results announced by email to all applicants / submitters. We aim to announce 3 weeks (21 days) after the abstract submission deadline but delays may occur.”

Selection results do not impact your admission to the meeting. Selection for registration fee waivers and travel grants is based on scientific merit, your current work or study location, the reasons for needing financial support, and the impact this event will have on your career.

Childcare grants will be allocated in the same timeframe (6-8 weeks before the event start date). Please note that priority will be given to early-stage researchers.
