    • The present invention is directed to novel tissue protective peptides. The tissue protective peptides of the invention may bind to a tissue protective receptor complex. In particular, the present invention is drawn to tissue protective peptides derived from or sharing consensus sequences with portions of cytokine receptor ligands, including Erythropoietin (EPO), that are not involved in the binding of the ligand to the receptor complex, e.g., to the EPO receptor homodimer. Accordingly, the tissue protective peptides of the invention are derived from the amino acid sequences of regions of cytokine receptor ligands that are generally located on or within the region of the ligand protein that is opposite of the receptor complex, i.e., are generally derived from amino acid sequences of regions of the ligand protein that face away from the receptor complex while the ligand is bound to the receptor. The invention is further directed to the consensus sequences for use in engineering a synthetic tissue protective peptide. These tissue protective peptides also include fragments, chimeras, as well as peptides designed to mimic the spatial localization of key amino acid residues within the tissue protective receptor ligands, e.g., EPO. The invention further encompasses methods for treating or preventing a disease or disorder using tissue protective peptides of the current invention. The invention also encompasses methods for enhancing excitable tissue function using tissue protective peptides of the current invention.
    • 本发明涉及新型组织保护肽。 本发明的组织保护肽可以结合组织保护性受体复合物。 特别地,本发明涉及来源于或共享共有序列的组织保护肽,其中部分细胞因子受体配体包括促红细胞生成素(EPO),其不参与配体与受体复合物的结合,例如与 EPO受体同二聚体。 因此,本发明的组织保护肽衍生自通常位于与受体复合体相反的配体蛋白的区域上或内部的细胞因子受体配体的区域的氨基酸序列,即通常衍生自氨基 当配体与受体结合时,配体蛋白的表面远离受体复合物的酸序列。 本发明还涉及用于工程化合成组织保护肽的共有序列。 这些组织保护肽还包括片段,嵌合体以及旨在模拟组织保护性受体配体例如EPO内的关键氨基酸残基的空间定位的肽。 本发明还包括使用本发明的组织保护肽治疗或预防疾病或病症的方法。 本发明还包括使用本发明的组织保护肽增强可兴奋组织功能的方法。

    • The present invention relates to a population of blood borne mammalian cells that express a unique profile of surface markers that includes certain markers typical of connective tissue fibroblasts, and are referred to herein as “blood-borne mesenchymal cells.” In particular, it relates to the isolation, characterization and uses of such blood-borne mesenchymal cells. The cells of the present invention can be distinguished from peripheral blood leukocytes by their distinct size, morphology, cell surface phenotype and biologic activities, and are likewise distinguishable from connective tissue fibroblasts by other surface phenotypic markers. These cells proliferate in culture, and in vivo, as demonstrated in animal models, are capable of migrating into wound sites from the blood. Therefore, such blood-borne mesenchymal cells may have a wide range of applications, including, but not limited to, the promotion of wound healing, tissue remodeling, and for gene therapy.
    • 本发明涉及表达包含结缔组织成纤维细胞典型的特定标志物的表面标志物的独特特征的血液载体哺乳动物细胞群,并且在本文中称为“血源性间充质细胞”。 特别地,它涉及这种血源间充质细胞的分离,表征和用途。 本发明的细胞可以通过其不同的大小,形态,细胞表面表型和生物活性来区别于外周血白细胞,并且同样可以通过其他表面表型标记物与结缔组织成纤维细胞区分开来。 这些细胞在培养物中增殖,并且如在动物模型中所证明的那样,能够从血液迁移到伤口部位。 因此,这种血源性间充质细胞可以具有广泛的应用,包括但不限于促进伤口愈合,组织重塑和用于基因治疗。
