Nuclear steroid receptor expressing cells in cycle. The nuclear label [³H]-thymidine is detected by autoradiography in sections from all experimental groups that were also stained for the nuclear steroid receptors (a) ER-α or (b) PR. All experimental groups contained epithelial cells that were ER-α/[³H]-thymidine or PR/[³H]-thymidine double positive. A cell double positive for the nuclear steroid receptor and [³H]-thymidine within the tissue section are displayed in the inset. ER, estrogen receptor; PR, progesterone receptor.
