RESEARCH INTERESTS
Radiotherapy is involved in 75% of all cancer treatments. The dose that can be delivered to the tumor however is limited to the tolerance of the surrounding normal tissues. Therefore, the Coppes lab focuses on the effects of radiation on normal tissues in vivo and in vitro organoid models.
Notch signaling is a driver of glandular stem cell activity and regenerative migration after damage Davide Cinat, Rufina Maturi, Jeremy P Gunawan, Anne L Jellema-de Bruin, Laura Kracht, et al. EMBO Journal, 2026 Organoid models have significantly enhanced our understanding of adult stem cell function, however, uncovering regulatory mechanisms governing rare and often quiescent stem cells in glandular organs remains challenging. Here, we employ an integrative multi-omics approach, combining single-cell RNA sequencing, bulk ATAC and RNA sequencing, to profile the cellular populations and signaling pathways characterizing a mouse salivary gland organoid model across different temporal stages and after radiation-induced damage. Our findings identify Sox9- and Itgb1/Cd44- expressing cells as primitive adult stem/progenitor populations with a critical migratory role in tissue repair. Notch signaling is a key driver of self-renewal and migration in response to irradiation. Additionally, scRNA-seq analysis of irradiated salivary gland tissue confirms these findings in an in vivo setting. Extending these findings to murine and patient-derived salivary, mammary and thyroid gland organoids, we reveal the conserved role of Notch signaling in coordinating stem/progenitor cell-mediated regeneration across glandular tissues. These insights position Notch signaling as a central regulator of glandular stem cell-like populations and as a promising therapeutic target for enhancing glandular tissue regeneration following cancer therapies.
lncRNAs: a new generation of targets and biomarkers in thyroid cancer Rufina Maturi, Matteo Esposito, Rob P Coppes, Gabriella De Vita European Thyroid Journal, 2026 Long non-coding RNAs (lncRNAs) are untranslated RNA molecules that regulate gene expression through diverse mechanisms, acting as scaffolds, guides, decoys, or signals. In thyroid cancer, the most prevalent endocrine malignancy, lncRNAs are increasingly recognized as key contributors to tumor development and progression. Elucidating these molecular mechanisms is essential for advancing diagnostic, prognostic, and therapeutic strategies. This review highlights major lncRNAs implicated in thyroid cancer, categorizing them as upregulated/oncogenes or downregulated/tumor suppressors and describing their mechanisms of action and interactions. lncRNAs are typically expressed at low levels and tightly regulated to preserve normal cell behavior. In thyroid cancer, they serve as crucial regulators of oncogenesis, frequently acting as competing endogenous RNAs that influence key signaling pathways. While most studies focus on miRNA sponging, other mechanisms are underexplored. Circulating lncRNAs offer potential for non-invasive diagnostics, and several lncRNAs show promise as therapeutic targets. Thus, continued research into the diverse functions of lncRNAs is vital to fully harness their clinical potential in thyroid cancer.
Hyaluronic Acid-silk Fibroin Hydrogel for Salivary Gland Tissue Engineering Maryam Hajiabbas, Cibele Pelissari, Dorian Parisis, Tobias Putz, Claudia D'Agostino, et al. Advanced Healthcare Materials, 2026 Cell‐material‐based therapies have emerged as a promising avenue within tissue engineering strategies for salivary gland (SG) regeneration. However, replicating the complex architecture and functional properties of SG tissue remains a challenge. In this study, we used an engineered in situ cross‐linked hydrogel designed to recapitulate the biochemical and rheological characteristics of SG, providing a platform for investigating SG cell behavior and organoid differentiation. Among hydrogel formulations, derived from enzymatically cross‐linked blends of tyramine‐conjugated hyaluronic acid (HA‐Tyr) and silk fibroin (SF), a blend of 2.5% HA‐Tyr and 4% SF4 (HA‐Tyr‐SF4) showed rheological properties partially comparable to native submandibular glands (SMG), achieving high cell viability. Comparative analyses of cell‐scaffold interactions in 2D and 3D cultures revealed that cell encapsulation within HA‐Tyr‐SF4 hydrogel enhanced cell‐cell spatial organization. Encapsulated NS‐SV‐AC cells and human SG organoids (hSGOs) exhibited morphogenesis, supported by transcriptomic data indicating upregulation of genes associated with SG development, extracellular matrix remodeling, and epithelial phenotype stabilization. Furthermore, hSGOs grown in HA‐Tyr‐SF4 or matrix (MA) of basement membrane extract (BME) displayed similar transcriptomic profiles. This study establishes HA‐Tyr‐SF4 as a reproducible, biologically active scaffold with substantial potential for SG tissue engineering and regenerative medicine applications.
IFN-I signaling enhances salivary gland stem and progenitor cell activity after irradiation Davide Cinat, Ryan van der Wal, Mirjam Baanstra, Abel Soto-Gamez, Rufina Maturi, et al. Science Signaling, 2025 The goal of radiotherapy in cancer treatment is to maximize DNA damage in tumors while minimizing harm to surrounding healthy tissues, especially to stem and progenitor cells essential for tissue regeneration and organ function. Here, we investigated the molecular responses to photon and proton irradiation, two key modalities in head and neck cancer treatment. Multiomics and in vitro analyses revealed that both photon and proton irradiation of mouse salivary gland organoids induced similar early responses, including DNA damage, micronuclei formation, increased amounts of the cytosolic DNA sensor cGAS, and type I interferon (IFN-I) signaling. In addition, both types of radiation induced comparable increases in the release of mitochondrial DNA (mtDNA) into the cytoplasm and stimulated the production of ZBP1, a cytosolic nucleic acid sensor involved in mtDNA recognition. However, proton irradiation resulted in a more pronounced loss of heterochromatin regulators and derepression of transposable elements at later times after irradiation, which was accompanied by increased accumulation of intracellular double-stranded RNA (dsRNA) and an enhanced RIG-I–mediated IFN-I response. Genetic and pharmacological modulation demonstrated its critical role for IFN-I signaling in enhancing salivary gland stem and progenitor cell activity after irradiation in vitro and in vivo. Our findings reveal more pronounced molecular changes after proton irradiation as compared with photon irradiation and uncover a proregenerative role of IFN-I signaling in the salivary gland, suggesting this pathway as a promising therapeutic target to mitigate radiation-induced side effects.
Patient-derived medullary thyroid cancer organoids: a potential model for mechanistic studies on diagnostics and therapy Eline C Jager, Luc H J Sondorp, Rufina Maturi, Inês F Antunes, Bettien M van Hemel, et al. European Thyroid Journal, 2025 Objective Medullary thyroid carcinoma (MTC) is a rare neuroendocrine thyroid tumor, with only 30 new patients annually in the Netherlands. PET imaging provides information on distant metastases, after which tyrosine kinase inhibitors (TKIs) may be initiated. The rarity of the disease impedes large controlled trials, and therefore the challenge of selecting the best TKI and PET tracer for individual patients persists. To explore whether an in vitro model could be developed to guide the selection of appropriate PET tracers or TKI therapies in the future, we aimed to establish an MTC organoid model for the first time. Methods Dispersed cells from MTC biopsies were suspended in Matrigel, allowing organoid formation. The self-renewal potential was tested by dissociation and re-plating cells and determining organoid-forming efficiency. MTC-specific gene and protein expression were characterized by qPCR and immunofluorescent staining. Moreover, MTC-organoids (MTOs) were exposed to TKIs and PET tracers in proof-of-principle experiments. Results Ten MTC biopsies were processed and successfully cultured as MTOs. MTC-derived cells showed self-renewal potency for several passages, indicating the presence of putative stem cells. Gene and protein expression of MTC-specific markers in tissue and MTOs, and function measurements showed the production of calcitonin and CEA. Interpretation of the preliminary experiments with TKIs and PET tracers was limited by sample size but demonstrates their future potential. Conclusion We were able to culture MTC organoids that resemble the original tissue in gene expression, protein expression, and functionality. However, international, multi-center studies are required to meet the standards for future clinical applications.
