Abstract: The skeletal system is crucial to the life activities of the organism,it provides the hematopoietic micro-environment,mechanical support,organ protection and other functions,as well as a reservoir of calcium and other minerals.The phenotypic diversity of chicken tailbone is a good resource for study of skeletal phylogeny and mechanism.To understand the molecular mechanism of skeletal developmental termination in the Rumpless chicken,this paper summarized the development of skeletal,the skeletal research in Rumpless chicken,and focus on the key signaling pathways of Notch and Wnt that influence the characteristics of rumpless and research progress of the Rumpless chicken.Target genes of Notch and Wnt signaling pathways and their interactions can form the characteristic of periodic expression,which is a molecular pathway regulating body segment formation and tailbone extension.However,the precise regulation of the interaction between the receptor and ligand and the core elements in the signaling pathway are still unclear,and more functional genomic and proteomic technology are needed for further study.
