balbiani body definition
The Balbiani body is an evolutionarily conserved asymmetric aggregate of organelles that is present in early oocytes of all animals examined, including humans. Although first identified more than 150 years ago, genes acting in the assembly of the Balbiani body have not been identified in a vertebrate.o investigate if bucky ball functions in the establishment of the earliest known polarized structure in zebrafish and Xenopus, the Balbiani body or mitochondrial cloud, we determined if the Balbiani body was affected in bucky ball mutants.
