Effect of hormones on growth and function of cultured canine tracheal epithelial cells.

Insulin (INS), endothelial cell growth supplement (ECGS), transferrin (TF), cholera toxin (CT), hydrocortisone (HC), triiodothyronine (T3), and epidermal growth factor ( EGF) were systematically examined for their effects on proliferation, ion transport activity, and morphological differentiation of canine tracheal epithelial (CTE) cells in culture. INS, ECGS, TF, and CT increase proliferation of CTE cells cultured on plastic Petri dishes but exhibit no acute effect on the bioelectric activity of freshly excised CTE. CT increases amiloride-insensitive transepithelial ion transport across both freshly excised canine trachea and CTE cultures. EGF has no effect on proliferation of CTE cells on plastic but induces hyperplasia of CTE cells on collagen matrices. EGF does not alter basal transepithelial ion transport across cultures but increases cellular responsiveness to beta-adrenergic stimulation. HC and T3 have no effect on proliferation or transepithelial bioelectric properties of CTE cells but improve morphological differentiation yielding cultures of complex epithelia containing cuboidal ciliated and nonciliated cells. These results demonstrate that growth and function of cultured CTE cells are affected by specific growth factors.[1]
