Biogenic amine-containing cells in the chicken lung.

J A Eaton, M R Fedde

    Poultry Science
    |May 1, 1978

    Summary

    Researchers identified two types of biogenic amine-containing cells in adult chicken lungs using formaldehyde induced fluorescence. These cells may regulate lung function or act as receptors controlling breathing.

    Area of Science:

    • Pulmonary biology
    • Cell biology
    • Neuroendocrinology

    Background:

    • Biogenic amine-containing cells play roles in various physiological processes.
    • The presence and function of these cells in avian lungs are not well understood.

    Purpose of the Study:

    • To identify and characterize biogenic amine-containing cells in the adult chicken lung.
    • To investigate the potential roles of these cells in regulating pulmonary function.

    Main Methods:

    • Formaldehyde induced fluorescence was employed to visualize biogenic amine-containing cells.
    • Cellular distribution and potential amine content (serotonin, catecholamine) were assessed.

    Main Results:

    • Biogenic amine-containing cells were identified in the parabronchial region of the adult chicken lung.
    • These cells were sparsely distributed and appeared to be of at least two distinct types.
    • One cell type likely contains serotonin, while the other likely contains a catecholamine.

    Conclusions:

    • The adult chicken lung harbors distinct populations of biogenic amine-containing cells.
    • These cells may function as regulators of pulmonary ventilation and perfusion.
    • Alternatively, they might act as receptors involved in the control of breathing.
