Progesterone Induces the Growth and Infiltration of Human Astrocytoma Cells Implanted in the Cerebral Cortex of the Rat

Figure 2

Effects of P₄ and RU486 on the growth and infiltration of U373 human astrocytoma cells implanted in the motor cerebral cortex of the rat. Vehicle (propylene glycol) (a); P₄ (b); RU486 (c); P₄ + RU486 (d). Tumor cells are marked with an arrow. Magnification is represented by 200 μm scale in (a)–(d) and by 100 μm scale in the inserts (c)-(d).
