DESCRIPTION, OVERALL (provided by applicant): A complex interaction of different processes play a critical role in the development of hematopoietic lineages, and among the most important are the controls of hematopoietic stem cell (HSC) commitment. Understanding this process is critical to understanding HSC function as well as self-renewal, and this understanding will lead to novel insights into manipulation of HSC for therapeutic purposes, as well as understanding disease processes which involve HSC, including leukemia. Finally, advances in understanding HSC commitment will serve as a model for understanding other types of stem cells. This program, "Hematopoietic Stem Cell Commitment," consists of 4 projects, all of which are interrelated and focused on understanding some aspect of HSC regulation and function. They include: Project 1: "Branching points of hematopoietic stem cell commitment", (Project Leader: Koichi Akashi, Dana Farber Cancer Institute, Harvard Medical School; Project 2, "Signal Transduction Mechanisms in Hematopoietic Stem Cells" (Project Leader: Roger J. Davis, University of Massachusetts Medical Center, Worcester); Project 3: "Runx1 in hematopoietic stem cells" (Project Leader: Dong-Er Zhang, Scripps Research Institute); and Project 4, "Regulation of C/EBP alpha in hematopoiesis" (Project Leader: Daniel G. Tenen, Beth Israel Deaconess Medical Center, Harvard Medical School). The administrative core will be responsible for many interactive functions of the program, including regular meetings, seminars, and communication among projects. A Biostatistics Core will provide direction with statistical design and analysis. PUBLIC HEALTH RELEVANCE: By combining a variety of approaches, including studies of transcriptional regulation, signal transduction, and knockout and knockin mice, we will provide valuable new information concerning the regulation of stem cell function.

描述，总体（由申请人提供）：不同过程的复杂相互作用在造血谱系的发展中起关键作用，其中最重要的是造血干细胞（HSC）承诺的控制。了解这一过程对于理解HSC功能以及自我更新至关重要，并且这种理解将导致对HSC的治疗目的的操纵的新见解，以及了解涉及HSC的疾病过程，包括白血病。最后，理解HSC承诺的进步将成为理解其他类型干细胞的模型。该程序“造血干细胞承诺”由4个项目组成，所有项目都相互关联并着重于理解HSC调节和功能的某些方面。其中包括：项目1：“造血干细胞承诺的分支点”（项目负责人：Koichi Akashi，Dana Farber癌症研究所，哈佛医学院；项目2，“造血干细胞中的信号转导机制”（项目领导者：Massachusets Medical Center，Massachusets Medical Center，worcester of Project project project strate;项目领导者； Dong-er Zhang，Scripps研究所； 公共卫生相关性：通过结合各种方法，包括对转录调控，信号转导以及敲除和敲除小鼠的研究，我们将提供有关干细胞功能调节的有价值的新信息。
