Laminin isoforms and their cell surface receptors in inflammation, tissue regeneration and cancer biology

In the oral cavity inflammatory diseases such as periodontitis may lead to tooth loss whereas malignant disorders such as squamous cell carcinoma may be lethal. Moreover, tissue regeneration by mesenchymal stem cells (MSCs) occurs in several entities.

The purpose of the present research is to investigate the interaction of cells with the extracellular matrix (ECM) and the relevance of this process to:

  • Leukocyte recruitment during immune and inflammatory responses (Fig. 1).
  • MSC biology.
  • Cancer biology (cancer cell stemness/survival/migration/proliferation and tumor invasion and metastasis) (Fig. 2).

Among ECM components, laminins are studied. The contribution of laminins and their cell-surface receptors to the migration and extravasation of different leukocytes is investigated, as well as the role of laminins in MSC stemness, differentiation and homing. In addition, the contribution of these ECM to cancer cell stemness and the dissemination of several tumors, including oral squamous cell carcinoma, is studied.
