Registrations to the LCI microscopy course 2025 will soon close!

There are a few spots left at our course (27 Jan – 14 Feb 2025): ‘Microscopy: improve your imaging skills – from sample preparation to image analysis’ (6 credits). Application deadline: 5th of November 2024.

This course is completely unique in that it is a highly hands-on course but because it runs completely remotely, your hands will be on your own microscope and your own sample. 😊

  • To see how the course can help your microscopy project, check out the course schedule 2025 and the alumni testimonies on the course webpage.
  • You can read the course syllabus and apply on this page. Make sure you check the eligibility criteria and click on the + sign at the top for more information.
  • If you cannot apply to the course, you can anyway follow any of the lectures (in blue on the course schedule) as they will be publicly broadcasted live on Zoom and accessible to anyone without registration. The schedule and zoom link are available on the course page.

The purpose of the LCI facility microscopy course is to provide PhD students, researchers and core facility staff who have some prior experience of microscopy with enough theoretical and practical knowledge about their OWN sample and their OWN microscope, to enable them to:

  1. assess and improve their sample so that it becomes suitable for data extraction from fluorescence images,
  2. make best use of the hardware available in their lab/facility,
  3. fully understand the acquisition parameters they need to set in their own microscope software,
  4. design their experiment from scientific question to image analysis using a strong knowledge base.

The aim is to provide you with tools to acquire on ANY wide field, confocal or light sheet microscope, images of your samples that reliably answer your scientific question.

The course is free of charge. Contact us (LiveCellImaging@ki.se) for enquiries.

Best practice to prepare figures with microscopy images

Here you can find information about a very interesting talk on the 5th of March (7pm, Swedish time) about the recommended practice to prepare figures containing microscopy images.

This talk is based on a recent Nature communications article Community-developed checklists for publishing images and image analysis.

The LCI open microscopy course starts on Monday! :)

Dear all

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 and you do not need to register.

The aim for this course is to improve the microscopy skills of students and researchers who have already used a microscope to acquire digital images of fluorescent samples but feel that more knowledge could help them.

Here is a selection of what we will talk about:

  • Optics and image formation,
  • Anatomy of a microscope
  • Objectives and refraction index
  • Cameras and detectors, Noise and background, Bit depth and saturation
  • Sample preparation, Immunostaining, Clearing and expansion
  • Resolution and contrast, Nyquist sampling, Microscope settings
  • Data handling, OMERO.figure, Requirements for image analysis, Colocalization
  • Image processing and analysis

Check our course webpage to see the course schedule (Broadcasted activities are in blue) and the Zoom link. Scroll down to read the kind testimonies of our dear students! 🙂

Here is the course syllabus.

For those who are on a far away time zome, we record all the live lectures and post them every evening on the LCI facility YouTube channel! 🙂

We hope that you will enjoy the LCI facility microscopy course!

Kindly forward to anyone who might be interested.

Spatial transcriptomics in Flemingsberg!

Spatial transcriptomics techniques are booming! It is now possible to identify where RNAs are located within a tissue! At the LCI facility, we routinely image samples labelled with RNAscope. If you use RNAscope, you might be interested in this workshop where you will learn how to label thick samples with RNAscope, and this symposium about automated RNAscope.

Additionally, we can now offer the 10x Genomics Visium technology on the South Campus, as a collaboration between 4 core facilities in Flemingsberg: LCI, FENO, SICOF and BEA core facilities!

Here is the workflow:

  1. We discuss your project and advise you for the preparation of your sample.
  2. You cut your sample and optimize the antibody or H/E staining yourself, under the guidance if the LCI staff to best preserve the RNAs.
  3. You image your tissue sections at the LCI facility.
  4. You transfer your section to SICOF who tags the RNAs and amplifies the library, using the 10x Genomics Visium technology.
  5. The library goes to BEA for sequencing.
  • Section size: max 6.5×6.5 mm or max 11×11 mm
  • Human or mouse
  • Paraffin-embedded or fresh-frozen
  • Labelled with H/E or fluorescent antibodies

Come and talk to us about your Spatial Transcriptomics project!

BII webinar about a great tool! TissUUmaps

The BioImage Informatics facility at Scilife organizes a new presentation on free and open-source tools: TissUUmaps, a browser-based tool for GPU-accelerated visualization and interactive exploration of millions of datapoints overlaying tissue samples.

Users can visualize markers and regions, explore spatial statistics and quantitative analyses of tissue morphology, and assess the quality of decoding in situ transcriptomics data. TissUUmaps provides instant multi-resolution image viewing, can be customized, shared, and also integrated in Jupyter Notebooks. TissUUmaps was created in collaboration between BIIF and the Wählby lab. You can read more about it and test the software on its web page: https://tissuumaps.github.io/
During the seminar, we will go through basic usage of TissUUmaps: installation, loading images, markers and regions, change visualization settings, and how to load / save / share projects. The webinar will be given by Christophe Avenel and will take place on March 3rd, 09:00-10:00 (instead of our normal Call4Help session). There will be time for questions and discussion, so we hope this event to be very interactive. Please register here.
