The Sumbalova Koledova laboratory at the Institute of Molecular Genetics (IMG)-BIOCEV Centre, Prague, CZ, is looking for a passionate, intellectually curious postdoctoral scientist specialized in bioinformatics with an interest in developmental and cancer biology. The research project FIBROFORCE aims to decipher the functional heterogeneity of fibroblasts during mammary gland development utilizing scRNA sequencing and spatial transcriptomic technology.
The postdoctoral fellow will have access to a unique set of scRNAseq and spatial transcriptomic data from mammary gland and mammary tumors. Their mission will be to identify markers of different cell populations and signaling pathways enabling cellular communication to improve our understanding of the role of the microenvironment in mammary gland development and tumorigenesis. Model building and validation will also exploit available public databases.
About the research group
In the Sumbalova Koledova’s Laboratory of Tissue Morphogenesis and Cancer we study processes and mechanisms, which govern epithelial morphogenesis and homeostasis, and how their deregulation can lead to developmental defects and cancer. We investigate the interplay of biochemical and mechanical signals in shaping epithelial sheets to functional structures, with particular interests in the role fibroblasts in this process. Our ultimate research goal is to understand, how organs are formed and how tumors emerge.
Using the mammary gland, a paradigmatic branched organ unique to mammals, as the main research model we seek answers to these main research questions:
- How is the branched pattern of glandular organs formed?
- What is the functional role of fibroblast heterogeneity in mammary gland development?
- How do fibroblast-mediated developmental programs contribute to tumor formation?
Our research strategy combines advanced organoid models, state-of-the-art imaging techniques, genetic mouse models, biosensors, single-cell and spatial transcriptomic analyses, mathematical modeling, and AI-driven image analysis.
