The Scientific Core has three major components: 1) Cell cultures, 2) Animals and 3) Microscopy. The Core will assist each of the projects by providing reagents and support services. These include characterized cells, breeding, genotyping, and phenotyping of mouse models, microscopy, in situ immunofluorescence imaging and histology. Scientific and technical support includes: 1. Routine isolation and maintenance of primary fetal rat calvarial-derived osteoblasts, marrow cells and calvarial osteoblasts from transgenic/knock-in mice as needed. 2. Maintenance of various osseous and non-osseous cell lines and cell lines with transgenes. Preparation and sterility testing of cell culture media, screeening of serum lots and enzyme reagents to ensure uniformity of cultures. 3. Monitoring growth and differentiation properties of cell lines for phenotype stability. 4. Preparation of adenovirus stocks of Runx2 proteins. 5. Maintenance of Runx2 knock-in/mutant mouse colonies as required for all three projects. This includes breeding, tagging, and identifying positive and negative mice by Southern blot or PCR analysis. 6. Routine preparation of embryos or tissues for phenotype characterization, which may include either whole embryo (3-Gal staining, frozen, plastic or paraffin embedding, sectioning and staining, and jnCT analyses. 7. Preparation of total cellular RNA and nuclear matrix proteins from tissues and cell lines. 8. Characterization and quality control of all antibodies used for in situ immunofluorescence. 9. Maintenance of all microscopes and software applications. 10. Data management of quantitative procedures to characterize distribution of wild type and mutant Runx2 transcription factors and their co-regulatory proteins.

科学核心有三个主要组成部分：1）细胞培养，2）动物和3）显微镜。核心 将通过提供试剂和支持服务来协助每个项目。其中包括特征 细胞，育种，基因分型，小鼠模型的表型，显微镜，原位免疫荧光 成像和组织学。科学和技术支助包括： 1.原代胎鼠颅骨源性成骨细胞、骨髓细胞和成骨细胞的常规分离和维持 根据需要从转基因/敲入小鼠的颅骨成骨细胞。 2.各种骨和非骨细胞系以及转基因细胞系的维持。制备 细胞培养基的无菌检查，血清批次和酶试剂的筛选，以确保 文化的一致性。 3.监测细胞系的生长和分化特性以获得表型稳定性。 4. Runx 2蛋白的腺病毒储备液的制备。 5.根据所有三个项目的要求，维持Runx 2敲入/突变小鼠集落。这包括 通过Southern印迹或PCR分析对阳性和阴性小鼠进行育种、标记和鉴定。 6.用于表型表征的胚胎或组织的常规制备，可能包括 全胚胎（3-Gal染色，冷冻，塑料或石蜡包埋，切片和染色，以及jnCT 分析。 7.从组织和细胞系中制备总细胞RNA和核基质蛋白。 8.用于原位免疫荧光的所有抗体的表征和质量控制。 9.维护所有显微镜和软件应用程序。 10.用于表征野生型和突变型Runx 2分布的定量程序的数据管理 转录因子及其共调节蛋白。
