PTPRC and neoplasm: Tumor analysis on a single cell level at study end revealed a profound infiltration of human CD45+ immune cells, mainly hCD56- CD3+ T cells but also hCD56+ NK(T) cells (Figure S7B), leading to a reduction of hCD45- mCD45- tumor cells from 67.5% to 36% (donor B) and from 75% to 57% (donor C) compared to control (Figure S7C).
