image: Fresh human breast tissue samples from healthy women are treated so that ducts and lobules are freed. These tissue microstructures contain many different cell types and remain viable. They still react to hormones and allow researchers to study the proliferation of cells in response to hormones, as well as biochemical changes. Scale bar: 0.2 mm. This image relates to a paper that appeared in the April 24, 2013, issue of Science Translational Medicine, published by AAAS. The paper, by Dr. T. Tanos at Ecole Polytechnique Fédérale de Lausanne in Lausanne, Switzerland, and colleagues was titled, "Progesterone/RANKL Is a Major Regulatory Axis in the Human Breast." view more
