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.

The LCI team

A few spots left at the LCI microscopy course 29/01-16/02 2024

There are a few spots left for the LCI core facility light microscopy course (29 Jan – 17 Feb 2024): Microscopy: improve your imaging skills – from sample preparation to image analysis’ (6 credits).

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

  • To see how the course can help your microscopy project, check the course webpage. Look at the course schedule 2024 and the alumni testimonies!
  • Also check the course syllabus to see the eligibility criteria. Also read what you will learn in the Course content and Intended Learning Outcomes sections.
  • If you cannot apply to the course, you can anyway follow any of the lectures (in blue on the 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.

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!

Time to register to the LCI microscopy course!

Dear all

It is time to enroll to the yearly light microscopy course run by the Live Cell imaging core facility (29 Jan – 17 Feb 2024): Microscopy: improve your imaging skills – from sample preparation to image analysis’ (6 credits).

  • Check the course schedule 2024 and the syllabus to see the course content and alumni testimonies.
  • Postdocs or registered PhD students can apply to the course.
  • Please read carefully the eligibility criteria in the syllabus and note that the last registration date is the 15th of November.
  • If you cannot apply to the course, you can anyway follow any of the lectures (in blue on the schedule) as they will be publicly broadcasted live on Zoom and accessible to anyone without registration. The schedule and zoom link are on the course page.

The purpose of this course is to enable PhD students and researchers who have already and recently used a microscope to acquire images of fluorescent samples, to improve their microscopy skills.

The course is NOT aimed at training people to use the LCI facility microscopes. The focus is instead on providing the students with enough theoretical and practical knowledge about their OWN sample and their OWN microscope, to enable them to:

1) prepare their sample and formulate their scientific question in a way that is suitable for data extraction from fluorescence images

2) properly use the hardware available in their lab/facility and 3) fully understand each parameter they need to set in the software in their lab/facility.

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

Please help us spread the word. 😃

The need to improve microscopy trainings

The LCI facility has just published an article about  ‘Improving light microscopy training routines with evidence-based education’. The article is now available in the Journal of Microscopy. We hope that this article will give useful tips to better design users’ training and improve their learning outcome. 🙂

Here is the abstract:

The low reproducibility of scientific data published in articles has recently become a cause of concern in many scientific fields. Data involving light microscopy is no exception. The low awareness of researchers of the technologies they use in their research has been identified as one of the main causes of the problem. Potential solutions have hinted at the need to improve technological and methodological education within research.

Despite the pivotal role of microscopy core facilities in the education of researchers being well documented, facility staff (FS) often learn their trade on the job, without receiving themselves any structured education about the technology they teach others to use. Additionally, despite endorsing an important role at the highest level of education, most FS never receive any training in pedagogy, the field of research on teaching and learning methods.

In this article, we argue that the low level of awareness that researchers have of microscopy stems from a knowledge gap formed between them and microscopy FS during training routines. On the one hand, FS consider that their teaching task is to explain what is needed to produce reliable data. On the other, despite understanding what is being taught, researchers fail to learn the most challenging aspects of microscopy, those involving their judgement and reasoning. We suggest that the misunderstanding between FS and researchers is due to FS not being educated in pedagogy and thus often confusing understanding and learning.

To bridge this knowledge gap and improve the quality of the microscopy education available to researchers, we propose a paradigm shift where training staff at technological core facilities be acknowledged as full-fledged teachers and offered structured education not only in the technology they teach but also in pedagogy. We then suggest that training routines at facilities be upgraded to follow the principles of the Constructive Alignment pedagogical method. We give an example of how this can be applied to existing microscopy training routines. We also describe a model to define where the responsibility of FS in training researchers begins and ends.

This involves a major structural change where university staff involved in teaching research technologies themselves receive appropriate education. For this to be achieved, we advocate that funding agencies, universities, microscopy and core facility organisations mobilise resources of time and funding. Such changes may involve funding the creation and development of ‘Train-the-trainer’ type of courses and giving incentives for FS to upgrade their technological and pedagogical knowledge, for example by including them in career paths. We believe that this paradigm shift is necessary to improve the level of microscopy education and ultimately the reproducibility of published data.
