Chemotherapy accelerates genomic aging of normal blood in children treated for cancer

Whole genome sequencing (WGS) data obtained from clonally expanded hematopoietic stem and progenitor cells (HSPCs) from pediatric cancer patients before and after therapy exposure. In addition, WGS data of cord-blood derived HSPCs clones exposed to various chemotherapeutics and radiation was obtained.

Dataset ID	Description	Technology	Samples
EGAD00001007078	Dataset contains WGS sequecing data from clonally expanded hematopoietic stem cells from 7 individual pediatric cancer patients. Samples were taken before (DX - diagnosis) or Follow-up (DX2/REM/FU - Diagnosis 2, remission or follow-up, respectively). In addtion, cord blood clones (Designated CB) treated with X-ray radiation, Cisplatin, Maphosphamide, Vincristine and Doxorubicin and untreated cord blood hematopoietic stem/progenitor cells were have been whole-genome sequenced. (Abbreviations RAD, CISPL, MAPH, VINC, DOX and CTRL, respectively)	Illumina NovaSeq 6000	115
EGAD00001011256	Dataset contains WGS sequencing data from bulk sorted therapy-related myeloid neoplasms (t-MN) and reference cells (MSCs/B cells/T cells). In addition, from 4 patients, also WGS data from single hematopoietic stem and progenitor cells, obtained from samples of t-MN diagnosis, are included. These are either clonally expanded before WGS, or DNA was directly amplified via the primary template-directed amplification (PTA) protocol (mentioned in the sample name).	Illumina NovaSeq 6000	80
EGAD00001011257	WGS data of clonally expanded HSPCs from a Li-Fraumeni patient at the time of second cancer (Burkitt lymphoma and <5% t-MN) after primary osteosarcoma diagnosis and a reference MSC bulk.	Illumina NovaSeq 6000	10
EGAD50000000447	Sanger sequencing data of cell lines derived from bulk MV4-11 cells, targeting the R248 locus of TP53, consisting of either wildtype or homozygous mutant lines.	AB 3730xL Genetic Analyzer	4
