Characterization of Embryonic Skin Transcriptome in at Three Feather Follicles Developmental Stages.

In order to enrich the genome and identify the gene expression profiles of primary and secondary feather follicles development, transcriptome assembly of skin tissues was established by analyzing three developmental stages at embryonic day 14, 18, and 28 (E14, E18, E28). Sequencing output generated 436,730,608 clean reads from nine libraries and assembled into 56,301 unigenes. There were 2,298, 9,423 and 12,559 unigenes showing differential expression in three stages respectively.
