Recent studies show that mammosomatotropes-cells that secrete both growth hormone and prolactin-are common in normal pituitary tissue. It is proposed that these dual hormone secretors serve as transitional cells for the differentiation of classical mammotropes during development, and for the functional interconversion of growth hormone and prolactin secretors in adults.
