Ls isolated from Stat3fl/fl;K14-Cre2 virgin glands in

Ls isolated from Stat3fl/fl;K14-Cre2 virgin glands in 3D Matrigel organoid culture [37] gave rise to branched solid organoids as expected while basal cells from Stat3fl/fl;K14-Cre+ glands produced rounded hollow organoids, similar to those formed by luminal cells (data not shown). In the light of these data, we suggest that Stat3 is also important for the maintenance of luminal progenitor proliferative potential.Whole mount staining of mammary glands of Stat3fl/fl;BLG-Cre2 and Stat3fl/fl;BLG-Cre+ females, collected four weeks after natural weaning.

A clear understanding of the evolutionary history of gene families is essential for studying their Title Loaded From File function, expression, and the evolutionary forces responsible for their diversification. Many evolutionary events such as gene duplication are important drivers of the expansion of gene families but can also confound functional genomics and gene expression studies that focus on orthologous genes.
