Abstract Interaction between parenchyma and stroma is essential for organogenesis, morphogenesis,
and differentiation. Mammary gland has being the chosen model for developmental biologist because the
most striking changes in morphology and function take place after birth. We have demonstrated a regulation
of triglyceride accumulation by protein factors synthesized by normal mouse mammary gland epithelial cells
(NMMG), acting on a cell line, 3T3-L1, long used as a model for adipogenesis. In this paper, we demonstrate
that this inhibitory effect seems to be shared by other cells of epithelial origin but not by other cell types. We
