MEIS1 and neoplasm: This identified tumor neuroectoderm-like cell-specific expression of important neuroectoderm neural precursor like-cell markers including CD34, PAX6, SOX2, MSI1, MEIS1, and TCF7L2, further validating the nature of the snRNA-seq neuroectoderm-like cells and the identification of these cells in situ despite their being a small minority of tissue cells analyzed spatially (Fig. 8K).
