摘要: Small peptide mimics of TGF-.beta., having the general sequence AA.sub.i -AA.sub.i+1 -AA.sub.i+2 followed by AA.sub.i+n shortly thereafter, have been prepared. In this sequence, AA.sub.i is alanine, asparagine, or leucine, AA.sub.i+1 is valine or isoleucine, AA.sub.i+2 is alanine, n is 3, 4, or 5 such that there are n-3 amino acid residues in between AA.sub.i+2 and AA.sub.i+n, and AA.sub.i+n is glutamic acid, aspartic acid, glutamine or asparagine. Because the essential requirement for TGF-.beta. activity is the peptide's ability to form a stable .beta.-bend structure under physiologic conditions, the inventive peptides are collectively referred to as .beta.-bend peptides. Compositions for applications such as tissue repair are also provided that comprise a biocompatible matrix having cytomodulin or a cytomodulin analog admixed with or carried by the matrix.
摘要翻译: 已经制备了具有通用序列AAi-AAi + 1-AAi + 2,随后是AAi + n的TGF-β的小肽模拟物。 在该序列中,AAi是丙氨酸,天冬酰胺或亮氨酸,AAi + 1是缬氨酸或异亮氨酸,AAi + 2是丙氨酸,n是3,4或5,使得在AAi + 2之间存在n-3个氨基酸残基 AAi + n,AAi + n为谷氨酸,天冬氨酸,谷氨酰胺或天冬酰胺。 因为TGF-β活性的基本要求是肽在生理条件下形成稳定的β-末端结构的能力,所以本发明的肽统称为β-末端肽。 还提供了诸如组织修复的组合物,其包含具有与基质混合或携带的细胞调节蛋白或细胞模型蛋白类似物的生物相容性基质。

摘要: Compositions suitable for pharmaceutical administration are provided in which one compound is a small peptide mimic of TGF-&bgr;. More preferably, pharmaceutical compositions of the present invention are formulated as combinations of two components, wherein one component includes a peptide mimic for TGF-&bgr; and the other component is structurally or biologically analogous to a small region of collagen and mimics the conformation recognized by collagen binding species. A particularly preferred combination is A-N-V-A-E-N-A (SEQ ID NO:1) and G-T-P-G-P-Q-G-I-A-G-Q-R-G-V-V (SEQ ID NO:17).

Compositions for applications such as tissue repair are provided that comprise a biocompatible matrix having cytomodulin admixed with or carried by the matrix.

摘要: Fibroblast cells are treated with a chemical inhibitor of protein kinase C such as staurosporine, in conjunction with functionally hypoxic micromass culture so as to be induced into chondrogenic differentiation. Such fibroblast-derived, chondrocyte-like cells may be seeded onto three-dimensional polymer scaffolds for use in the repair of articular cartilage lesions, and thus can obviate the need for invasive techniques to harvest autologous chondrocytes from a limited supply of existing articular cartilage, or to avoid the need for obtaining allogeneic chondrocytes from non-biocompatible donor tissues.
