Glucose transport by epithelia prepared from harvested enterocytes

Glucose transport by epithelia prepared from harvested enterocytes

Transformed and cultured cell lines have significant shortcomings for investigating the characteristics and responses of native villus enterocytes in situ. Interpretations of results from intact tissues are complicated by the presence of underlying tissues and the crypt compartment. We describe a simple, novel, and reproducible method for preparing functional epithelia using differentiated ente...

Ion Transport by Pulmonary Epithelia

The lung surface of air-breathing vertebrates is formed by a continuous epithelium that is covered by a fluid layer. In the airways, this epithelium is largely pseudostratified consisting of diverse cell types such as ciliated cells, goblet cells, and undifferentiated basal cells, whereas the alveolar epithelium consists of alveolar type I and alveolar type II cells. Regulation and maintenance ...

Chloride transport by high-resistance heterocellular epithelia.

Morphogen transport in epithelia.

We present a general theoretical framework to discuss mechanisms of morphogen transport and gradient formation in a cell layer. Trafficking events on the cellular scale lead to transport on larger scales. We discuss in particular the case of transcytosis where morphogens undergo repeated rounds of internalization into cells and recycling. Based on a description on the cellular scale, we derive ...

Transport Mechanisms in Epithelia

The author describes some auscultory findings in ventricular tachycardia, which will aid the reader when he is confronted with diagnosing either supraventricular tachycardia or ventricular tachycardia. An excellent chapter discusses evaluation of the severity of hypertension based on auscultory findings. These also come from the author's studies. The author, in a chapter on functional and innoc...
