Do you want to contribute to top quality medical research?

We are located in a modern research hub called NEO at Karolinska Institutet in Huddinge. You will be working in an international and interdisciplinary research environment, where collaborative efforts are encouraged. We always aim for an open and welcoming environment. Together with other research groups, we offer state-of-the art core facilities providing cell sorting techniques, microscopy, sequencing, mouse facilities, and provide access to clinical samples. This position will be supported by the prestigious Swedish Research Council Starting Grant. The appointment will be for two years with a possible extension for up to two additional years.

Your mission

The failure to regenerate tissue with age is a major health issue. A contributor to this decline is the loss of stem cell function. Despite the essential role of stem cells, it is still unclear how they fail to maintain their functions during aging and disease. We discovered a new aspect of stem cell aging in vivo: cellular enlargement. With age and damage, stem cells increase in size causing their functional decline. However, we are only beginning to understand how size impacts stem cell fitness and the physiological importance of this process remains unsolved.

We are seeking a highly motivated and ambitious individual from universities around the world to join the research team of Assistant Professor Dr. Jette Lengefeld as a Postdoctoral Researcher to mechanistically understand novel mechanisms of human stem cells that drive aging and disease. The Lengefeld research group uses hematopoietic stem cells from mice and human bone marrow donations to discover how deregulation of cellular size is connected to aging and cancer.

Your project will utilize hematopoietic stem cells from elderly or patients with leukemia to identify factors that facilitate stem cell aging and leukemia by single sequencing, creating xenotransplants using “humanized” mice and in vitro systems to investigate the underlying mechanisms

Your profile
