Hypertrophic and hyperplastic changes of mucus-secreting epithelial cells in rat airways: assessment using a novel, rapid, and simple technique.

Determination of hyperplastic and hypertrophic changes of mucus-secreting cells in animal airways has been performed in the past by using histologic, immunologic, and/or molecular biologic approaches. Histologic techniques are tedious and time-consuming. The other approaches require specific antibodies and cDNA probes that have proved difficult to develop. Described here is a method for the rapid estimation of hyperplastic and hypertrophic …
