Many investigators at Yale University (Medical School and College) have a long-standing interest in musculoskeletal disorders. These investigators represent numerous departments and discjplines. This interest in the pathophysiology of the skeleton has created a number of collaborative projects among interested investigators. As a result of these interactions, investigators have sought to develop cell culture techniques within their own laboratories often leading to expensive duplication of already existing technologies. Although standard techniques are available, intra-laboratpry variation in the quality and number of cells is unavoidable. This variation is exacerbated by the difficulties in isolating bone cells from the myriad of genetically engineered murine models now available. To address this Institutional need, the Cell Core was developed as part of the initial application of the YCCMD. It remains one of the five major components of the Center. As part of the Cell Core's new initiatives, isolation of adipocyte precursors and adipocyte differentiation protocols are now available. In addition, murine mesenchymal stem cells may be obtained through the Cell Core. The goal of the Cell Core is to facilitate the experimental use of authentic primary, isolated mouse and rat osteoblasts, osteoclast-like cells generated in vitro, osteoblast precursors, and bone marrow-derived adipocytes. As part of our imaging initiative, the Cell Core has expanded its services to include small animal high-resolution radiographs. The new Specific Aims of the proposal are to provide the following services: 1. Isolate and culture primary murine and fetal rat calvarial osteoblasts. This includes large-scale preparations for biochemical analyses and RNA and DMA purification. 2. Differentiate murine osteoclast-like cells from bone marrow or spleen cells by: a) in vitro coculture with osteoblasts or induction with Oncostatin-M or parathyroid hormone; b) culture with MCSF and RANKL. 3. Grow and differentiate mouse bone marrow derived osteoblast/adipocyte progenitors (marrow stromal cells) 4. Supply primary mouse mesenchymal stem cells (MSCs). 5. Support a cell bank that provides access to a large number of cryoperserved cell lines. 6. Provide small animal bone densitometry (DXA) and radiographs. 7. Train investigators for in vitro isolation and culture of osteoblasts, osteoclasts and progenitor cells, so that investigators appropriately trained can establish these techniques in their laboratories The Core will provide cells to Center members in a coordinated manner, such that expenses and duplication of effort are minimized. The Cell Core will also provide support to the Pilot and Feasibility Projects as part of our continuing effort to attract new investigators to musculoskeletal research. The Core has an established

耶鲁大学（医学院和学院）的许多研究人员长期以来对 肌肉骨骼疾病。这些调查员代表了众多部门和学科。这 对骨骼病理生理学的兴趣创造了许多合作项目 有兴趣的调查人员。由于这些相互作用，研究人员试图开发细胞培养物 他们自己实验室内的技术通常会导致昂贵的重复现有技术 技术。尽管可以使用标准技术，但实验室内的质量和数量存在差异 细胞的破坏是不可避免的。从无数骨细胞中分离骨细胞的困难加剧了这种差异。 现已提供多种基因工程小鼠模型。为了满足这一机构需求，细胞核心是 作为 YCCMD 初始应用的一部分而开发。它仍然是该系统的五个主要组成部分之一 中心。作为 Cell Core 新举措的一部分，脂肪细胞前体和脂肪细胞的分离 分化方案现已推出。此外，还可以获得小鼠间充质干细胞 通过细胞核心。 Cell Core 的目标是促进真实初级、 分离的小鼠和大鼠成骨细胞、体外产生的破骨细胞样细胞、成骨细胞前体和骨 骨髓来源的脂肪细胞。作为我们成像计划的一部分，Cell Core 已将其服务扩展到 包括小动物高分辨率射线照片。 该提案的新具体目标是提供以下服务： 1. 分离培养原代小鼠和胎鼠颅骨成骨细胞。这包括大规模 用于生化分析以及 RNA 和 DMA 纯化的制剂。 2. 通过以下方式区分小鼠破骨细胞样细胞与骨髓或脾细胞：a) 体外共培养 使用成骨细胞或使用制瘤素-M 或甲状旁腺激素进行诱导； b) MCSF 培养 和兰克尔。 3. 培养和分化小鼠骨髓来源的成骨细胞/脂肪细胞祖细胞（骨髓 基质细胞） 4. 供应原代小鼠间充质干细胞（MSC）。 5. 支持提供大量冷冻细胞系的细胞库。 6.提供小动物骨密度测定（DXA）和X光片。 7. 培训成骨细胞、破骨细胞和祖细胞体外分离和培养的研究人员 细胞，以便经过适当培训的研究人员可以在实验室中建立这些技术 核心将以协调的方式向中心成员提供单元，从而避免费用和重复 的努力被最小化。 Cell Core 还将为试点和可行性项目提供支持，作为 我们不断努力吸引新的研究人员进行肌肉骨骼研究。核心有一个既定的
