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.

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

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.

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

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 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.

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

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.

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…

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…

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’.

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…

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.

This programme video is presented in Dutch

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.

Biology is the study of life. Are you interested in understanding life, from the molecular level to entire ecosystems? Do you want to use your understanding and knowledge of biology to benefit the health of both humans and the environment? If so, Biology is the right study programme for you.

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

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

Quantitative biology means exploiting mathematical modelling and computer simulation as a tool to gain additional insights into the meaning of experimental data. Discover in this minor when and how to apply these tools, in a multidisciplinary setting.

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…

Cell-based medicinal products (CBMPs), such as CAR T cells, are highly complex biopharmaceutical products offering various treatment options for serious illnesses such as cancer or autoimmune diseases.

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…

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

The master's specialisation Molecular, Cellular and Organismal Biology at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Atherosclerosis, in particular rupture of atherosclerotic plaques, is the underlying cause of most heart attacks or strokes and is the leading cause of death worldwide.

Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.
