Description
Kinga Skieresz-Szewczyk and Hanna Jackowiak trace tongue hardening in goose embryos in a 2026 tissue staining study. Cornification builds the tough surface layer from structural proteins plus the enzyme transglutaminase-1. Two tongue coverings, one with dead surface nuclei and one without, were followed from day 9 to day 25 of incubation across early, transformation, and prehatching stages.
Protein signals began early, then surged as layers split and a temporary periderm formed. By prehatching both coverings had a cornified layer, yet only some protein patterns matched adult birds. Hardening thus starts about two thirds through development, and final maturation still lags behind hatching.
