From: Mouse mammary tumour virus (MMTV) and human breast cancer with neuroendocrine differentiation
Specimens | MMTV | Synaptophysin | Chromogranin |
|---|---|---|---|
Mouse mammary tumour | 7/7 (100%) | 7/7 (100%) | 7/7 (100%) |
Human breast cancer (selected for MMTV positivity) | 22/22 (100%) | 2/22 (9%) | 2/22 (9%) |
Normal human breast controls | 0/39 (0%) | 0/39 (0%) | 0/39 (0%) |
