Malignant Melanoma Microecosystem: Immunohistopathological Insights Into the Stromal Cell Phenotype

This paper explores the relationship between the dermal extracellular matrix and cutaneous malignant melanoma, suggesting that ECM involvement may play a key role in the cancer's growth, invasiveness, and initial metastasis.

This review discusses the role of cellular heterogeneity and interaction in the skin's ability to maintain homeostasis despite cancer-causing mutations, noting the potential for these cells to also drive tumor formation, but reports no new clinical results.

This study suggests that melanoma tumor cells exhibit intrinsic plasticity, challenging the applicability of the cancer stem cell model to this malignancy.

New findings suggest targeting IL-23 could treat psoriasis, skin cells can adapt to new roles, direct conversion of skin cells to blood cells may aid cell therapy, removing certain tumor cells could boost cancer immunotherapy, and melanoma may have many tumorigenic cells, not just cancer stem cells.

This study explored the immune environment of the hair follicle's bulge region and suggested that its unique signaling may prevent melanoma formation by lacking necessary proinflammatory signals for full oncogenic transformation, indicating potential strategies for melanoma prevention by replicating this immune-privileged environment.
