Department of Cell Biology

The Department of Cell Biology is one of the three Departments that are part of the Center for Molecular Medicine of the University Medical Center (UMC) Utrecht. The Department of Cell Biology is an integrated academic center for fundamental and translational research, and education in the fields of cancer, stem cells and immunology. Its research fully fits within five of the six focus areas (speerpunten) of the UMC Utrecht: Personalized Cancer Care, Regenerative Medicine and Stem Cells, Immunology and Infection,Child Health and Brain.

The faculty of the Department of Cell Biology comprises ten principal investigators, who with their independent teams work on various interrelated research topics within the biomedical life sciences. This creates a unique environment where a variety of experimental and theoretical expertises and competencies come together.

  • Prof. Judith Klumperman: Understand how genetic mutations lead to cellular disorganization and disease, with special emphasis on diseases related to the cellular digestive system, the endo-lysosomes.
  • Prof. Paul Coffer: Understand the molecular mechanisms underlying (stem) cell fate decisions with the context of immunology, cancer and regenerative medicine.
  • Prof. Madelon Maurice: Mechanisms of Wnt signaling in stem cells, development and cancer.
  • Prof. Ger Strous: Cell biology of the growth hormone receptor.
  • Dr. David Egan: Identification and validation of novel targets for cancer therapy.
  • Dr. Catherine Rabouille: (part-time associated) Regulation of secretion during development and by growth conditions
  • Dr. Catherine Robin: (part-time associated) The self-renewing and differentiation of hematopoietic stem cells
  • Dr. Peter van der Sluijs: Molecular mechanisms of membrane traffic regulating cell surface remodeling.

Together these research teams integrate cell and molecular biology, biochemistry, genetics, light & electron microscopy and high-throughput screening methods in order to tackle a diversity of biomedical questions with innovative approaches and from unique angles. In addition, a large variety of model systems are employed, including yeast, human-derived cell lines, adult stem cells, tissues and mouse models.

The Department also hosts three technical facilities available to research groups from within the UMC Utrecht, Hubrecht Institute and other interested parties: the Cell Microscopy Core (CMC) and the Cell Screening Core (CSC). The CMC assists microscopy-based research by providing access to state-of-the-art light and (immuno)-electron microscopy equipment and expertise. The CSC provides technological support to high throughput screening projects that require the use of automation. The focus of the CSC is on automated microscopy screens, so-called 'High Content Screens'. The CSC makes use of libraries of chemical compounds, siRNAs and other reagents such as miRNAs and provides library management.
The iPSC facility assists scientists in reprograming somatic cells to iPSC.

News

As from June 1st 2016, Madelon Maurice has been appointed Professor of Molecular Cell Biology.
Madelon Maurice has received a prestigious VICI grant from NWO. Title: Controlling the controller: Regulation of signals that guide stem and cancer cell growth and differentiation. Stem cell-mediated tissue renewal is precisely controlled by signals from the environment. These signals are often misused by cancer cells. Madelon aims to understand how stem cells capture and process these signals in order to better intervene in these processes in tissue repair and cancer.http://www.nwo.nl/actueel/nieuws/2015/nwo-kent-36-prestigieuze-vici-beurzen-toe.html
Autophagy is a process that is switched on if there are insufficient nutrients and it is important for various cellular functions. The research supported by this grant will study how autophagy affects the immune system. Autophagy-manipulation could help to control autoimmune diseases such as (juvenile) arthritis.
The group of Fulvio Reggiori, together with that of Maurizio Molinari (IRB Bellinzona) and Matthias Peter (ETH Zurich),has received a Sinergia grant of approximately 1’550’000 Swiss Francs from the Swiss National Science Foundation (SNF), to study the selective degradation of the endoplasmic reticulum by autophagy.

Magdalena Lorenowicz was awarded the Reumafonds grant to study the molecular mechanism regulating the immunosuppressive properties of exosomes derived from mesenchymal stromal/stem cells and their potential use as a treatment for rheumatoid arthritis.

Work on how cargoes are transported through cells traces back to previous Nobel winners George Palade, Albert Claude, Christian de Duve  and Günther Blobel (1999). The development of electron microscopy and cell fractionation techniques by Palade, Claude and de Duve paved the way for their discoveries of such subcellular organelles/structures as endoplasmic reticulum, lysosomes, and ribosomes as well as the assembly of secretory proteins. Blobel brought the field to the next level by uncovering a bar code on newly synthesized proteins and the characterization of the barcode reader that is required for their targeting and delivery to the correct intracellular compartment.
