Table 2. Expression of steroid hormone receptors PR and ER by immunohistochemistry in tumor tissue from which patient-derived organoid models were created.

Cases are organized by histologic subtype and stage/grade. Cases that were utilized for analysis of progesterone-mediated gene expression changes are underlined, whereas cases that were included in drug testing studies are italicized. N.D.: not determined; no tumor: no tumor cells were present for analysis in the stained slide.
