ImmunoFISH for bone marrow stromal cell markers in case 1. PDGFRβ, blue; X, magenta; Y, green; DAPI, gray. a PDGFRβ-immunoFISH analysis in the tumor specimen. Recipient-derived PDGFRβ(+) SCSSNs and donor-derived PDGFRβ(−) SCSSNs are observed. Recipient-derived PDGFRβ(+) SCSSNs are indicated by white arrows. Scale bar: 100 μm. b Proportions of donor cells in a region comprising 50 continuous HPFs. Each analysis was carried out in six regions of the tumor area. The means (SD, total number of PDGFRβ(+) SCSSNs, number of sections) were as follows: 0.7% (0.8%, 578, 2) in case 1, 2.4% (1.9%, 258, 3) in case 2, and 1.8% (2.1%, 182, 2) in case 3. (PDGFRβ-immunoFISH images for cases 2 and 3 are shown in Supplementary Figs. 2 and 3). c PDGFRβ-immunoFISH analysis in the bone marrow specimen. Most PDGFRβ(+) cells are recipient-derived (white arrow). Cells marked weakly positive for PDGFRβ (weak+) are suspected to be donor-derived (yellow arrow). Scale bar: 100 μm
