Quantification of hPSCs in Metastatic Sites
| Metastatic sites | Number of male hPSCs expressed as proportion of cancer cells (mean ± SE) |
|---|---|
| Liver (n = 5) | 5.78 ± 2.93% |
| Diaphragm (n = 3) | 6.14 ± 4.28% |
| Mediastinum (n = 2) | 4.44 ± 2.26% |
| All metastatic nodules | 5.62 ± 1.81% |
Serial sections of metastatic nodules were stained for the Y chromosome (FISH) and for cytokeratin. Data are expressed as the number of Y chromosome–positive cells per 100 cytokeratin-positive cells (cancer cells).
