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.

Leiden has a long history in the treatment of blood cell cancer. Research to find better therapies never stands still. One of the potential treatments currently being worked on is a ‘living medicine’.

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 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…

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 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.

Three speakers, three fascinating science stories and a well-filled lecture hall. The Niko Tinbergen Lecture had a successful restart on 10 December 2019.

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

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

Leiden biophysicist Stefan Semrau was granted an NWO Vidi earlier this month. He will use the grant to study the role of electricity in embryonic development and tissue regeneration.

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…

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.

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.

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

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…

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

Develop a prototype combined chemical-microbial enzymatical process for the sustainable, green recycling and revalorization of polyamides and polystyrene

How can we broaden youth participation in STEM Learning

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

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.

The master’s programme Biology at Leiden University offers seven specialisations ranging from Cell Biology to Molecular Genetics. The programme prepares you for a career in research within or outside academia.

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…

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.

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

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.

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

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

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…

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…

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

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…

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

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,…

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…
