In our unpublished pilot study, we have discovered an interesting finding whereby inflammatory cells extend from the tumour to and invading fat in the subcutaneous tissue and\u002For around the appendageal structures in the dermal skin in metastatic melanomas with distinct architectural changes within the fat. This finding was consistently present in metastatic and absent in non-metastatic melanomas. This new finding has both clinical and pathophysiological credence. Archival tissue blocks or human cell lines will be used in the first instance. As mitigation, experiments will be repeated with conditioned media obtained from co-culture of mixed primary immune cells obtained from peripheral blood mononuclear cell (PBMCs) and adipocytes induced from stem cells.\n\nThis study aims to:\n\n* Investigate if the crosstalk between fat cells and tumour-infiltrating inflammatory cells defines the aggressiveness of primary cutaneous melanomas.\n* Identify and perform biological spatial analysis of the inflammatory cells between the tumour and fat in the primary tumours.\n* Investigate the interactions of fat cells and\u002For inflammatory cells in mediating melanoma cellular plasticity.\n\nThe patients have not provided consent and will be justified in this application",[50],"Melanoma (Skin Cancer)","NOT_YET_RECRUITING","2025-12-08",{"date":54,"type":55},"2025-12-19","ACTUAL",{"date":57,"type":46},"2026-01",{"date":59,"type":46},"2027-01",{"name":5,"class":6},1]
