Single-cell transcriptomics reveals a conserved embryonic progenitor in different human cancers
Abstract
Cellular plasticity, a critical feature of embryonic development, is often reactivated in cancer, enabling tumor cells to acquire stem-like properties and facilitate uncontrolled growth. This study compares cellular plasticity in cancer and early human development by integrating single-cell data from three cancers and embryoid bodies. The analysis identifies a shared, highly proliferative progenitor-like state, driven by an E2F-TFDP transcriptional axis and enriched in key cell-cycle regulators UBE2C, TOP2A, BIRC5, and NUSAP1. Functionally linked to cell-cycle progression and DNA repair, this state acts as a lineage hub within tumors. Spatial transcriptomics revealed that this state is enriched in lung adenocarcinoma and in lung tissue with basal cell hyperplasia, a potential precursor to squamous cell carcinoma. Validation across eight cancer types demonstrates a prevalence of this program in tumors versus normal cells. Collectively, these findings define a conserved mechanism of tumor plasticity with potential for early detection and targeted therapy.
