Filtering the noise of embryonic development
Résumé
Embryonic development is the generation of a multicellular organism from a single cell. During this process, tissues and organs are differentiated and positioned at different parts of the organism. In this paper, we deal with the precision (embryo to embryo variations) of this process by looking at the early development of the fruit fly embryo. We show that precision of the antero-posterior gene expression pattern is hard coded at the very first stages of development. The noise reductionmechanismis extremely robust and resistant to mutations, in contrast to the actual position of the tissues themselves.
