Figure 2

Stromal cells proliferate in pubertal mammary tissue. The nuclear label [3H]thymidine is detected in mammary tissue that has been processed for (a) ER-α or (b) PR. Black arrows designate stromal cells that are [3H]thymidine positive, indicating cells that have recently undergone cell cycle. Scale bars = 5 μm. ER, estrogen receptor; PR, progesterone receptor.
