Single-cell Analysis of Neoplastic Plasma Cells Identifies Novel Myeloma Pathobiology Mediators and Potential Targets

Newly diagnosed symptomatic and relapsed/refractory myeloma is a clonal plasma cell (PC) dyscrasia that arises from precursors which have been studied utilizing bulk or single-cell (sc) techniques. By combining scRNA-sequencing with scB-cell receptor (BCR)-sequencing, we found more dysregulated genes in monoclonal PCs compared with analyses of the entire CD138+ population, which includes non-neoplastic/polyclonal PCs. Paired tumor and non-tumor WGS was performed to evaluate the presence of IgH-associated translocations and hyperdiploidy events, initially detected by FISH, in a subset of samples included in this study.

Dataset ID	Description	Technology	Samples
EGAD50000001177	This dataset includes paired tumor and non-tumor WGS data from patients diagnosed with newly diagnosed (n = 6), refractory/relapsed multiple myeloma (n = 3) or plasma cell leukemia (n = 1). These samples presented >95% tumor PCs in bone marrow aspirates. Plasma cells and T cells (non-tumor cells) were isolated from bone marrow aspirates using a magnetic approach.	Illumina NovaSeq 6000	20
