This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Recent findings that stem cells from a particular organ are capable of giving rise to mature tissues in other organs have changed our thinking about the role of stem cells in human disease and development. Bone marrow stem cells are among the most well characterized stem cells and they have been shown to be proficient in forming non-blood tissues. It is likely that bone marrow provides the cellular substrates for many organs and that bone marrow derived progenitors are recruited to areas of injury or wounds. There is evidence of this for the liver and heart. Understanding the dynamics of homing and recruitment of these bone marrow cells to the skin will be valuable in developing treatments for a variety of disorders. We have shown in preliminary studies that bone marrow cells can engraft into wounds and form skin structures. In a clinical study performed on human patients, we have evidence that bone marrow can accelerate healing and close chronic wounds that have failed to heal by other traditional and advanced treatments administered in specialized centers. The studies proposed will identify those bone marrow stem cells that home to skin and form skin structures. Purified bone marrow stem cells and whole bone marrow will be examined for their potential to engraft and reconstitute skin structures in wounded skin.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 最近的研究发现，来自特定器官的干细胞能够在其他器官中产生成熟组织，这改变了我们对干细胞在人类疾病和发育中的作用的看法。骨髓干细胞是最具特征的干细胞之一，并且它们已被证明擅长形成非血液组织。很可能骨髓为许多器官提供细胞基质，并且骨髓衍生的祖细胞被募集到损伤或伤口区域。有证据表明，这对肝脏和心脏。了解这些骨髓细胞归巢和募集到皮肤的动力学将对开发各种疾病的治疗方法有价值。我们已经在初步研究中表明，骨髓细胞可以移植到伤口和形成皮肤结构。在一项对人类患者进行的临床研究中，我们有证据表明，骨髓可以加速愈合，并关闭在专业中心进行的其他传统和先进治疗未能愈合的慢性伤口。这项研究将确定那些骨髓干细胞的家园皮肤和形成皮肤结构。将检查纯化的骨髓干细胞和全骨髓在受伤皮肤中移植和重建皮肤结构的潜力。
