Succinic dehydrogenase activity during palate formation in the Mongolian gerbil.

RESUMO

The palatal shelf epithelium of the Mongolian gerbil was examined for succinic dehydrogenase activity prior to, during and the after palatal fusion (days 18-20 post coitus). Enzyme activity was present during all stages examined, and was noted even in the epithelial pearls of fused palates. The presence of SDH activity in these epithelial pearls lends support to the theory 'epithelial stretching', and questions the theory of 'programmed cell death' in relation to the loss of the epithelium along the plane of fusion.
