Thèmes de recherche

Despite significant progress in diagnostic and treatment modalities, breast cancer metastases persist as a prominent public health concern. Addressing the challenge of metastasis formation and development requires a deeper comprehension of how cancer cells colonize and adapt to distant sites.

Our research group is committed to unraveling the intricate cellular and molecular mechanisms underlying the formation of breast cancer metastases, with the ultimate goal of pioneering novel therapies to combat metastatic disease. Employing a comprehensive approach, we integrate state-of-the-art techniques such as primary organoid culture, single-cell RNA sequencing, and advanced imaging methods. Through these methodologies, we aim to contribute meaningful insights to the field and advance the development of effective interventions against breast cancer metastasis.
