show Abstracthide AbstractThe goal of this study is to obtain the transcriptomes of chicken magnum in different natural developmental stages. There are totally five stages researched in this study and they are named D1, D2, D3, D4 and L. D1 to D4 are the abbreviations of developmental stage 1 to developmental stage 4 and L means laying stage. D1 refers to the lag phase (about 7 weeks old) in which the magnum has very slight change; D2 refers to the early proliferation phase (about 13 weeks old); D3 refers to the late proliferation phase (about 16 weeks old); D4 refers to the early differentiation phase (about 17 weeks old).
