Dr. Karen Plaut Lab​

Mammary Gland Biology Lab​

The overall objective of our lab is to understand how cells, growth factors, hormones, organ systems and the environment interact to regulate mammary development and lactation. Presently our research is focused in two main areas: understanding the role of epithelial and stromal interactions in mammary development and neoplasia; and understanding how changes in physiology and metabolism are coordinated across multiple tissues during the periparturient period to prepare for and maintain lactation.
