Treatment with special stem cells seems to be a good option for suppressing the immune system in organ transplants. Researchers are trying to learn from processes that take place in the human body during pregnancy.

The book Uitdagend gedifferentieerd vakonderwijs bij Janssen, Hulshof and Van Veen describes a 'generative toolkit' for adapting education by teachers.

A teacher perspective

Chemist Roxanne Kieltyka has received an ERC Starting Grant of 2 million euros. In her lab, she creates gels that mimic the instructive material that supports cells in our body. With the grant, she aims to make these gels stiff and tough, and to create a bio-printed miniature heart ventricle.

Many teachers in secondary education take differences between pupils into account . PhD research by Saskia Stollman (ICLON) shows that they need room to experiment and the support of the school management

Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Three types of PLCs are studied, varying on the dimension of autonomy of and interdependency between teachers: Joint work, Aid and assistance and Shared practices.

On 12 April 2022 Alok Oak successfully defended a doctoral thesis and graduated.

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

Epithelial-mesenchymal plasticity (EMP) and tumor cell migration play an important role in cancer progression, and an improved understanding of the mechanisms underlying these concepts is essential for developing new targeted approaches.

How do teachers’ knowledge, practices, perceptions, job satisfaction and workload in secondary education develop during a school innovation in the context of differentiated student development?

The research in this thesis is focused on tomographic reconstruction based on two imaging modalities in electron microscopy.

Embryonic stem cells have the remarkable ability to develop into any type of cell. On their way to become for example a liver or a heart cell, they must repeatedly decide between alternative developmental paths. How they make these decisions is largely unknown. An international team of biophysicists…

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.

A new therapy for the serious Graft-versus-Host disease

The Leiden University Medical Center (LUMC), the Danstem Institute from the University of Copenhagen and the Murdoch Children’s Research Institute in Melbourne have received 300m euros from the Novo Nordisk foundation. The aim of this new international consortium is to bring stem-cell based therapies…

Research has shown that the impact of feedback can be very powerful on second language acquisition. However, how to provide adaptive feedback on speaking skills in foreign languages and how to provide differentiated support in secondary schools in regular secondary schools classes of often 25-30 students?…

This project aims to analyze and increase student motivation and achievement during the first three years of secondary school with an intervention that focuses on development of students’ talents.

How can we broaden youth participation in STEM Learning

Cell adhesion signaling

Methods of treatment for chronic illnesses are limited. Doctors and researchers at Leiden University Medical Center (LUMC) and Leiden University are working on new therapies as an alternative for organ transplants. The goal is to cure the illnesses by restoring organs to their original function. Stem…

What distinguishes a tumour cell from a healthy cell? Researchers are trying to answer this question as precisely as possible. Certain differences could eventually lead to new therapies.

We study cell-fate decision-making using embryonic stem cells as a model system. Stem cells integrate a large number of cues to direct their development into a great variety of cell types.

The single cell group (SCG) is part of the Metabolomics & Analytics Centre Our research is centered around developing innovating analytical methods tailored for small-volume, or single cell analysis to enable metabolomics-driven systems biology in personalized health strategies. We are always on…

The research within the Division of Cell Systems and Drug Safety, headed by Prof. Bob van de Water, is focused on novel therapeutic modalities and novel concepts in early drug discovery, in order to develop more effective and safer therapeutic strategies. We generate advanced cell and computational…

In this thesis, single-cell approaches were applied to characterize the impact of aging on the immunological B cell landscape in different models of atherosclerotic cardiovascular disease, with the goal to identify and study new B cell-associated biomarkers and therapeutic targets to halt atherosclerosis…

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Synthetic or artificial cells are vesicles, often lipid vesicles, with wide ranging applications from drug delivery to nanoreactors in biocatalysis. We are developing polymer-lipid hybrid vesicles for applications in compartmentalised biocatalysis, in which the polymer has been shown to greatly enhance…

Atherosclerosis is the most prominent underlying pathology of cardiovascular disease and an important cause of major adverse cardiovascular events.

In this thesis, we describe the potential of cell mechanical phenotyping for immune cell characterization, diagnosis, drug testing, as well as treatment of disease.

Mechanical interactions between cells and their environment play an important role in many biological processes.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

The cellular metabolism of immune cells constitutes an important part of their proper function and activation. Using T cells as an example, this phenomenon is highlighted by the metabolic reprogramming that occurs in these cells upon activation.

A research goal for ABS is to develop miniaturized platforms for research in (stem)cell, in-vitro systems and application in clinical and preventive research. Combined with the high throughput, this development will make it possible to study the dynamics of pathogenesis in human and cellular models…

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

The CMCB brings together microbial cell biology expertise in Leiden. It aims at optimal resonance between the groups and maximal exploitation of the available infrastructure and to develop innovative cross-boundary technology platforms.

Cardiovascular disease is a major global burden and atherosclerosis is the main underlying pathological process.

Regenerative medicine is a new way of treatment that helps impaired cells, tissues, and organs work well again. We do this by repairing, replacing, or restoring cells, tissues, and organs after damage from illness or injury. This includes treating long-term diseases such as diabetes, kidney diseases,…
