Aggressive oral cancer can be identified at an early stage by changes in lymphatic vessels Oral cancers with a high risk of recurrence can be identified at an early stage by examining the lymphatic vessels of the tumour.

Oral cancers with a high risk of recurrence can be identified at an early stage by examining the lymphatic vessels of the tumour. The high number of proliferating lymphatic vessels predicted cancer recurrence and death better than any other previously known risk factor for oral cancer.

A key finding of our last study is that soluble and immobilized CCL21 gradients cooperate to fine-tune different steps of lymphatic migration, revealing a new layer in leukocyte guidance.

This work was only possible thanks to an amazing team effort!

Fibroblastic reticular cells direct the initiation of T cell responses via CD44 - Nature CD44 expressed by fibroblastic reticular cells in secondary lymphoid organs regulates trafficking of dendritic cells, and thus has an essential role in the priming of T cells and the adaptive immune response.
