The dynamically evolving cell states and ecosystem from benign nevi to melanoma

Description:
Approximately 30% of non-chronically sun-damaged melanomas originate from nevi, yet the dynamic changes and crucial mechanisms driving the transition from benign nevi to melanoma remain elusive. Here, we performed single-cell transcriptome sequencing on multiple paired tissue sites from 5 patients diagnosed with melanoma arising in congenital melanocytic nevi (CMN), identifying four distinct states of melanocyte subpopulations during the progression from nevi to melanoma, characterized by dynamic changes in their composition, functions, malignancy, and regulatory pathways. Our study provides a high-resolution atlas of the malignant transformation of melanoma from nevi and highlights potential targets for further investigation. Ultimately, we developed a malignant progression model capable of predicting patient prognosis and malignant progression status using bulk RNA sequencing (RNA-seq) data.
