Clonal evolution of hematopoietic stem cells after autologous stem cell transplantation
The impact of exogenous stressors, such as cancer chemotherapies, on the genomic integrity and clonal dynamics of normal hematopoiesis is not well defined. We conducted whole-genome sequencing on 1,276 single-cell-derived hematopoietic stem and progenitor cell (HSPC) colonies from ten patients with multiple myeloma treated with chemotherapies and six normal donors. Melphalan treatment significantly increased the mutational burden, producing a distinctive mutation signature, whereas other chemotherapeutic agents had minimal effects. Consequently, the clonal diversity and architecture of post-treatment HSPCs resemble those observed in normal elderly individuals, particularly through the progression of oligoclonal hematopoiesis, thereby suggesting that chemotherapy accelerates clonal aging. Integrated phylogenetic analysis of matched therapy-related myeloid neoplasm samples traced their clonal origin to a single-HSPC clone among multiple competing clones, supporting a model of oligoclonal to monoclonal transformation. These findings underscore the need for further systematic research on the long-term hematological consequences of cancer chemotherapy. Analysis of whole-genome sequencing data from hematopoietic stem and progenitor cells taken from patients with myeloma shows how treatment shapes clonal architecture and sheds light on the evolution of treatment-related myeloid neoplasms.

Nature Genetics publishes the very highest quality research in genetics. It encompasses genetic and functional genomic studies on human and plant traits and on other model organisms. Current emphasis is on the genetic basis for common and complex diseases and on the functional mechanism, architecture and evolution of gene networks, studied by experimental perturbation.
Integrative genetic topics comprise, but are not limited to:
-Genes in the pathology of human disease
-Molecular analysis of simple and complex genetic traits
-Cancer genetics
-Agricultural genomics
-Developmental genetics
-Regulatory variation in gene expression
-Strategies and technologies for extracting function from genomic data
-Pharmacological genomics
