Stephen Lowe Young
Professor Emeritus of Medicine
Although I no longer am actively involved in research, my prior work experience is given below:
My laboratory work focussed upon the cell biology of the lung epithelium: during development, including the processes of branching morphogenesis and second, during the maintenence of lung surface forces through the epithelial secretion known as surfactant.
We emphasized a morphologic approach utilizing the full range of ultrastructural techniques, supplemented with molecular biologic techniques that allow structure function correlations.
I have been involved in clinical trials examining vaccination against influenza and examining the value of inhaled steroids, both experiments in patients with COPD.
I am recognized mainly for work in surfactant and lung development.
Lung surfactant; alveolar type II cell; branching morphogenesis; lung development
