背景资料：

陈迁教授长期以来致力于骨骼关节发育和衰老的疾病机理研究和治疗，具有世界一流的研究水平，是分子生物学、转化医学和骨科领域的国际权威专家。1992年在Tufts大学医学院获得细胞分子和发育生物学博士学位。1992年至1994年间在哈佛大学/麻省总医院完成博士后工作。自从2002年起，被聘为美国著名“常青藤”盟校之一的布朗大学终身教授，Michael G. Ehrlich MD特聘主任教授，时年38岁（为布朗大学医学院历史上最年轻的终身特聘教授）。自从2007年，主持建立了由美国国立卫生研究院（NIH）支持的杰出生物医学研究中心（COBRE），并任主任和首席负责人。此研究中心是全美八十多个杰出生物医学研究中心中，仅有的两个研究骨骼关节的中心之一。作为国际骨科关节研究的领军人物，在骨骼关节研究领域，校外研究经费在全美（美国和加拿大）排名第二。 2012年9月起担任西安交通大学前沿医学科学研究所所长兼骨骼关节疾病和治疗研究中心主任。其研究领域包括软骨病，关节炎，骨折愈合，细胞外基质及生物力学传导的分子机制。在国际骨科和关节炎医学领域具有重要影响力。已编撰发表“骨关节炎的诊断，治疗和手术（Osteoarthritis: Diagnosis, Treatment and Surgery）”等专著，在国际学术期刊发表的多篇论文为分子生物学在骨科领域应用的奠基性研究。其论文被引用近2000余篇次，H-index为29（2014年04月29日数据）。

其代表性成果包括：1）骨骼发育的分子生物学奠基性研究揭示软骨内骨化的分子生物学机理；成功建立了一系列软骨细胞分化的标志分子，比如骨胶原十号（type X collagen）和其他软骨基质分子。这些奠基性工作发表在PNAS ，Development, JBC等世界著名刊物上，为骨骼发育领域奠定了分子生物学基础。2）骨骼软骨的生物力学信号分子传导与机理的开创性研究；揭示和鉴别了多个骨骼中调控生物力学信号传导的重要基因，并发表了一系列首创性文章。这些文章被大量引用（单篇引用多达200次）并广泛影响生物力学研究的各个领域。3）软骨发育不良和骨关节炎调控基因的开创性研究；鉴别和认定关节软骨在发育或衰老的过程中，导致软骨组织损伤和退化的重要基因。多项研究第一次揭示软骨基质分子的基因编码与这些疾病的重要关系，发表在JCB, MBC, Developmental Biology。4）骨骼和关节退化病理与治疗转化研究；开发新的诊断和治疗骨骼关节损伤和退化疾病（例如骨关节炎）的方法。通过干扰分解代谢相关的细胞分子和趋化分子，研发了新型治疗方法来抑制软骨组织的损伤和退化。开发了动物模型来模拟软骨损伤和退化疾病的的病理学特征。这些模型对于新药和新治疗方法的研发具有不可估量的作用，并发表在Arthritis & Rheumatism, JBC, JBMR. 其在生物医学前沿的研究领域，作出突出贡献并多达16次获得美国和国际重要科技奖项，包括J.V. Satterfield 关节炎研究员奖 (美国关节炎研究基金会青年研究员最高奖)；美国国立卫生研究院独立科学家奖；诺华基金会科学家奖（当年全世界唯一获奖者）；Kappa Delta 青年研究家奖（全美骨科研究最高荣誉）。已授权美国和国际发明专利两项。
