First, to illustrate the scalability of Epiclomal with aneuploid single-cell cancer epigenomes, we analysed 558 tumour xenograft single epigenomes (called InHouse data) from two patients (SA501 and SA609) with triple-negative breast cancer and one patient (SA532) with ER+PR-Her2+ breast cancer (Table B in S1 Material) sequenced using the PBAL method [7]. This evidence concerns the gene ERBB2 and breast carcinoma.
