  2. Angiogenesis and angioregression gene expression analyses in swine corpus luteum

    De Andrea Ribeiro, Luciana <1971>Alma Mater Studiorum - Università di Bologna2007

    The corpus luteum (CL) lifespan is characterized by a rapid growth, differentiation and controlled regression of the luteal tissue, accompanied by an intense angiogenesis and angioregression. Indeed, the CL is one of the most highly vascularised tissue in the body with a proliferation rate of the …
