Second branchial arch lineages of the middle ear of wild-type and Hoxa2 mutant mice.

Developmental dynamics : an official publication of the American Association of Anatomists - 1 Sept 2005

O'Gorman Stephen

Abstract excerpt

Our current understanding of the evolution of the mammalian middle ear was first suggested by embryological studies from the 19th century. Here, site-specific recombinase-mediated lineage tracing was used to define the second branchial arch contribution to the middle ear of wild-type and Hoxa-2 mutant embryos. The processus brevis of the malleus was found to arise from second arch tissues, making it the likely...
