The epithelial polarity programme (EPP) is organized in response to extracellular cues and executed through the establishment of an apical–basal axis, intercellular junctions, epithelial ...

During tissue morphogenesis, ... mechanism that requires differential positioning of adherens junctions controlled by modulation of epithelial apical–basal polarity.

You have to poke a hole in the tissue to inject things into the apical side. People have successfully injected viruses this way to study infection. However, that is very difficult, ... Moreover, they ...

Using a molecular cellular compass, individual cells in complex organisms know which way is up or down, in epithelial cells known as apical-basal polarity. Determining the orientation is essential ...

Thus, a precordial or apical systolic murmur with a high-pitched component calls for painstaking search for a basal murmur with a rough quality; when this is found the diagnosis of aortic stenosis ...
