Functional Deconstruction of distinct fibroblast subsets in skin physiology and disease

Skin fibroblasts arise from two distinct lineages during embryogenesis, which have unique functions in skin development and homeostasis. In mouse skin, one lineage gives rise to the upper, papillary dermis, including fibroblasts of the dermal papilla, dermal sheath and arrector pili muscle, required for hair follicle (HF) formation. The other lineage forms the lower dermis, including the reticular fibroblasts that synthesize the bulk of the fibrillar extra-cellular matrix (ECM), and the preadipocytes and adipocytes of the hypodermis. Accordingly, distinct fibroblast subsets exist in human skin. Apart from their essential role during skin development, the subpopulations have unique functions during wound healing and fibrosis, and possibly other skin pathologies such as skin cancer.

Our laboratory is dissecting the immunomodulatory role of fibroblasts in melanoma and non-melanoma skin cancer, and how targeting specific subsets can be used for anti-cancer therapies. In addition, our lab is also investigating if modulating dermal signaling can redirect regeneration upon injury to a more scarless phenotype. Furthermore, we aim at developing therapies for fibroblast-mediated skin pathologies such as scleroderma and keloids, which lack an effective clinical treatment regimen.

Techniques, methods & infrastructure

We use a broad range of methods including state-of-the-art cell and molecular biology methods, 3D in vitro culture systems (human skin equivalents, organoid cultures), next generation sequencing, single-cell transcriptomics, flow and mass cytometry (CyTOF), in vivo lineage tracing techniques and cutting-edge imaging technologies including imaging mass cytometry, and conditional knock-out mice or murine skin disease models to unravel the role of distinct fibroblast subsets in skin physiology and pathology.
