Comparing organ development with transcriptomes

Developing organs are far from being a mass of identical cells. The expression of thousands of genes is regulated, which modulates the behavior and fate of complex cell populations on top of distinguishing them.
Principal component analysis is a useful tool to compare transcriptome timeseries


We show that comparing transcriptomes of different molar germs (lower/upper molar), different molar parts (buccal/lingual) and different species yield insights in the nature and abundance of cell populations throughout development. These are precious informations to understand how development results in different final morphologies and differs between species.
