MWM Biomodels GmbH is a spin-off company of the LMU Munich and Minitube, specialized in the development and characterization of transgenic large animal models for biomedical research. Current projects are focused on the development, characterization and implementation of genetically tailored pigs as disease models (diabetes mellitus, cardiovascular diseases, rare monogenic diseases) and as tissue donors for xenotransplantation.

MWM Biomodels offers support starting from the design of a project, the development of expression and targeting vectors, the generation of genetically modified large animals, their phenotypic characterization and the performance of preclinical studies. MWM Biomodels is an experienced partner in publically funded research consortia, such as EU-funded Marie-Curie Training Networks and COST Actions, or national networks funded by the Federal Ministry of Education and Research (BMBF) or the Bavarian Research Council (BFS).

About Us

MWM Biomodels GmbH is a spin-off company of the LMU Munich and Minitube, specialized in the development and characterization of genetically engineered large animal models for biomedical research. Current projects are focused on the development, characterization and implementation of genetically tailored pigs as disease models (diabetes mellitus, cardiovascular diseases, rare monogenic diseases) and as tissue donors for xenotransplantation.

The translation of novel discoveries from basic research to clinical application is a long, often inefficient and costly process. Consequently, “translational medicine” became a top priority. Relevant animal models are critically important for the discovery of key disease mechanisms, targets for medical interventions and subsequent development of new therapies. Rodents are the most popular, but findings in rodents are in many disease areas very different from those in human patients. Thus, animal models mimicking human anatomy and physiology more closely are urgently required. In this respect, pigs are excellent candidates to bridge the gap between basic research and clinical trials.

MWM Biomodels has unique expertise in the generation and phenotypic characterization of genetically tailored porcine disease models, particularly for pathophysiological studies of carbohydrate and lipid metabolism and for monogenic diseases, such as Duchenne muscular dystrophy and Laron syndrome (growth hormone receptor deficiency). The spectrum of phenotypic profiling is continuously expanded, mainly in collaboration with academic institutions. In particular, MWM Biomodels is closely collaborating with the Center for Innovative Medical Models (CiMM), a unique research center for the development of translational animal models at LMU Munich.

MWM Biomodels supports projects of academic institutions, e.g. in the framework of common grant applications (including BMBF, BFS, NIH), and performs contract research for Biotech Companies and the Pharmaceutical Industry.

MWM Biomodels offers a broad spectrum of research services, including project design, development of expression and targeting vectors, generation of genetically modified large animals, their phenotypic characterization, and performance of preclinical studies.
