In terms of cost and efficiency considerations, candidate animals for experiments will play key roles. Small size Binlang-pig, outer surface coating with white skin and hairs, was bred from domestic Lanyu-100 in 2010. Thus, generation of EGFP (enhanced green fluorescence protein) transgenic Binlang-pig for experiment purposes possess the native and industrialized potentiality of biomedical application, prospects for academic excellence, innovations in scientific research or technological development, and impact on research field and international competitiveness, advantageous to paper acceptable and patent apply subsequently. Mesenchymal stem cells (MSCs) have been isolated from bone marrow, periosteum, trabecular bone, adipose tissue, synovium, skeletal muscle and deciduous teeth, and so on. They also can be expanded with high efficiency, and induced differentiation into multiple lineages under defined culture conditions. These cells have generated a great deal of interest because of their potential use in regenerative medicine and tissue engineering, and there are some dramatic examples, derived from both pre-clinical and clinical studies, that illustrate their therapeutic value. In addition, consistent expression of reporter gene incorporating into genome of implanted MSCs will facilitate the progress for verifying their functions and differentiation potential in vivo. The bone marrow-derived MSCs isolated from transgenic animal expressing reporter gene possessed the characteristics of identical expression pattern, and this strategy is favorable to track their fate after transplantation and differentiation. Hence, the first year plan to generate transgenic Binlang-pig carrying PCX-EGFP transgene which includes EGFP cDNA under the control of a chicken beta-actin promoter and cytomegalovirus enhancer by pronuclear microinjection. The second year will establish the pig model of stem cell therapy for osteoporosis, germplasma preservation, somatic cell nuclear transfer, and isolated marrowderived mesenchymal stem cells, ready to keep in Bioresource Collection and Research Center, Food Industry Research and Development Institute for patent apply.基因轉殖豬綠色螢光蛋白質賓朗豬骨髓間葉幹細胞Enhanced Green fluorescence proteinTransgenic pigBinlang pigMesenchymal stem cells
