Western blot results in (A) show the pattern of expression for Cr-1, Netrin-1, Nanog and Oct4 in tissue extracts from postnatal mouse mammary gland at different stages of development. Results from densitometric analysis of the Western blots in (A) are shown in (B). Similar to the immunostaining results, expression of Oct4 protein remains fairly constant in the mouse mammary glands during the different stages of development analyzed. Cr-1 and Nanog shows a decrease in protein expression in the mouse mammary glands during lactation and early involution whereas Netrin-1 expression is highest during these same developmental stages. Densitometric values (OD units) were normalized to the epithelial content of the mammary gland, as determined by the expression for cytokeratin CK18.
