Are you fascinated by embryonic development? Are you excited by the idea of imaging the dynamic activity of developmental signaling pathways in a 3D in vitro stem cell model for early embryogenesis? Then this may be the job for you!
We are looking for an enthusiastic PhD candidate who is eager to study how individual pluripotent cells respond to developmental signals using gastruloids as a model system. The position is supported by an NWO-ENW-XL consortium grant and will be a highly collaborative effort between the University of Amsterdam, Radboud Universiteit, the Netherlands Cancer Institute and the Hubrecht Institute.
You will be embedded in the Developmental, Stem Cell and Cancer Biology group (led by dr. Renée van Amerongen), which is part of the
Swammerdam Institute for Life Sciences in the Faculty of Science at the University of Amsterdam. Research in our group aims to understand how complex tissues are built and maintained. We study this at multiple different levels - "from man or mouse to molecule" - and with a specific focus on WNT and BMP/NODAL signaling. See
our website for more details.
What are you going to do?The early mammalian embryo is composed of pluripotent stem cells that can generate all cell types of the body. At the start of gastrulation, instructive signaling cues determine which developmental trajectory the different cells will take. At the same time, this stem cell population is highly heterogeneous with cell-to-cell variation at the transcriptomic and epigenomic level. The goal of our NWO-XL consortium is to unravel how this collection of heterogenous stem cells becomes an organized structure.
Your focus will be on studying the interplay between BMP, WNT and NODAL signaling using live cell imaging in a 3D model of early embryonic development, termed "gastruloids". At the beginning of your PhD, a technician will provide experimental support to help you get started. As part of our larger consortium network, you will get the opportunity to incorporate experimental single-cell -omics approaches in collaboration with PhD students and experts throughout the Netherlands.
During your PhD research, you will learn and apply a variety of techniques, including (but not limited to) DNA cloning, 2D mESC culture and targeting using CRISPR/Cas9, 3D gastruloid culture, live-cell confocal microscopy, FACS sorting, and manipulation of gastruloids using a combination of classical developmental biology and state-of-the-art (epi)genome perturbation approaches.
Tasks and responsibilities:
- complete and defend a PhD thesis within the official appointment duration of four years;
- use state of the art molecular cell biology approaches to visualize, manipulate and track individual cells in 3D;
- perform your experiments in a systematic and well controlled manner;
- keep accurate records by thoroughly documenting and organizing your work;
- discuss your work in our lab and consortium meetings, incorporate feedback and give input to others;
- assist in teaching and supervise BSc/MSc students during their research internship;
- participate in the Faculty of Science PhD training programme.
You will get the opportunity to:
- Learn a wide variety of molecular, cell biology and imaging techniques;
- Learn, develop and apply quantitative image analysis;
- Build a network as part of our consortium collaborations;
- Present your work at (inter)national meetings;
- Continuously hone your academic, professional and personal skills.
