Investigate the cellular renewal, lifespan, and migration dynamics of cells within taste buds.
Inhibited epithelial cell mitosis in rat tongues using colchicine injections.
Recorded electrical activity from the taste nerve bundle to assess sensory responsiveness following chemical stimulation.
Tracked cell division and migration paths into taste buds using tritiated thymidine radioautography.
Colchicine treatment reduced taste nerve electrical responses to chemical stimulation by 50% at 3 hours post-injection.
Tritiated thymidine showed dividing epithelial cells surrounding taste buds produce daughter cells that migrate inward toward the center.
Taste bud cells displayed an average lifespan of 250 ± 50 hours, with individual cell durations varying substantially.

Implication

Laboratory study demonstrates rapid cell renewal and inward migration in rat taste buds, suggesting sensory function depends on continuous cell turnover.
