PROJECT SUMMARY (Transgenic Mouse Genome Editing Core) The Transgenic Mouse Genome Editing Core (TMGEC) has been an integral part of the Diabetes Research Center (DRC) at the Perelman School of Medicine, University of Pennsylvania since 1997. The TMGEC is directed by Dr. Douglas Epstein, PhD, Professor and Vice Chair, Department of Genetics. Dr. Epstein is an experienced investigator with considerable expertise in technologies and experimental approaches that center on mouse models of disease, developmental genetics, and genome editing. An experienced technical team, led by Dr. Jean Richa, provides expertise in a full range of transgenic technologies, enabling the TMGEC to regularly introduce new and improved services. Services provided by the TMGEC include the generation of genetically altered mice by direct genome editing (CRISPR/Cas9), DNA microinjection into fertilized oocytes to create transgenic lines, the generation of chimeric mice via embryonic stem cell injection into blastocysts. The TMGEC also carries out embryo re-derivation, embryo and sperm cryopreservation, in vitro fertilization (IVF), and centralized cryopreservation storage. The TMGEC uses state-of-the-art laser conditioning of the zona to facilitate IVF and has intracytoplasmic sperm injection capability to complement IVF services. Newly developed services during the current funding period include the major expansion of cryopreservation services with corresponding expansion of the cryopreservation facility, integration of CRISPR/Cas9 direct genome modifications with a newly established Perelman School of Medicine CRISPR core, and electroporation of DNA and RNA into embryos to increase throughput and decrease wait time for TMGEC services. In the past 5 years, 48 DRC investigators used TMGEC services to generate 225 independent mouse lines (primarily by CRISPR/Cas9 editing) and to store 134 mouse lines (by cryopreservation). Usage is expected to stay the same, or increase over the next five years. Additional Institutional (non-DRC) support is provided for equipment maintenance and facility infrastructure upgrades and maintenance. An extensive network of collaborations exist within the DRC focusing on the use of genetically modified mouse models of diabetes, obesity and metabolic disorders. These joint projects among DRC investigators highlight the role of the TMGEC not only as an essential technical resource but also as a key hub for collaborative research among DRC investigators, as exemplified by the numerous joint publications and successful grant applications arising from mice generated, stored, and/or re-derived by the TMGEC.

项目摘要（转基因小鼠基因组编辑核心） 转基因小鼠基因组编辑核心 (TMGEC) 已成为糖尿病研究不可或缺的一部分 自 1997 年起在宾夕法尼亚大学佩雷​​尔曼医学院设立中心 (DRC)。TMGEC 是 由遗传学系教授兼副主席 Douglas Epstein 博士指导。爱泼斯坦博士是一位 经验丰富的研究者，在技术和实验方法方面拥有丰富的专业知识 研究小鼠疾病模型、发育遗传学和基因组编辑。经验丰富的技术团队， 由 Jean Richa 博士领导，提供全方位转基因技术的专业知识，使 TMGEC 能够 定期推出新的和改进的服务。 TMGEC 提供的服务包括生成 通过直接基因组编辑（CRISPR/Cas9）对小鼠进行基因改造，将 DNA 显微注射到受精卵母细胞中 创建转基因系，通过将胚胎干细胞注射到囊胚中产生嵌合小鼠。这 TMGEC 还开展胚胎再衍生、胚胎和精子冷冻保存、体外受精 (IVF)、 和集中冷冻保存。 TMGEC 使用最先进的透明带激光调节技术 促进 IVF 并具有胞浆内单精子注射能力来补充 IVF 服务。新开发的 当前供资期间的服务包括大幅扩展冷冻保存服务 冷冻保存设施的相应扩展，CRISPR/Cas9直接基因组的整合 使用新建立的佩雷尔曼医学院 CRISPR 核心进行修饰，以及 DNA 电穿孔 和 RNA 到胚胎中，以提高吞吐量并减少 TMGEC 服务的等待时间。在过去的5 多年来，48 位 DRC 研究人员使用 TMGEC 服务生成了 225 个独立的小鼠品系（主要通过 CRISPR/Cas9 编辑）并存储 134 个小鼠品系（通过冷冻保存）。使用量预计将保持在 保持不变，或在未来五年内增加。为设备提供额外的机构（非刚果民主共和国）支持 维护和设施基础设施升级和维护。广泛的合作网络 刚果民主共和国内存在，专注于使用糖尿病、肥胖症和肥胖症的转基因小鼠模型 代谢紊乱。刚果民主共和国调查人员之间的这些联合项目凸显了 TMGEC 的作用，不仅是 一个重要的技术资源，也是刚果民主共和国研究人员之间合作研究的关键中心，例如 以大量联合出版物和由小鼠产生的成功资助申请为例， 由 TMGEC 存储和/或重新导出。
