Illustrating the generalized trends of miR-200 expression throughout the main stages of mammary gland development. miR-200 expression is relatively low in the newborn, pubertal, and virgin mammary gland when EMT is a dominant process [71]. miR-200 expression increases throughout pregnancy, peaking during lactation and remaining high during involution to facilitate alveologenesis and support lactation [71, 75,76,77,78].
