BRBseq performed on tumoroids and corresponding renal tumor tissues
To evaluate genetic similarities between tumoroids and the corresponding tumor tissues, we performed RNA sequencing of cells for each experimental condition. Since we injected human cancer cells into mice, cancer cells in the tumors were human while microenvironmental cells (i.e. Fibroblasts, Immune cells,…) were derived from mice. Thus, the RNA sequencing datasets generated from ACHN or 786-O tumor tissues (AxM and 7xM) and their respective tumoroids (AxTy and 7xTy) were mapped on human and mouse reference genome.
