    • The invention provides methods, compositions and devices for inducing tissue-specific regeneration in a mammal, or for stimulating proliferation of mammalian progenitor cells. The present methods, compositions and devices make use of osteogenic protein 1 (OP-1), which is appreciated herein as a tissue morphogen, i.e., a substance competent to induce tissue-specific morphogenesis of mammalian body tissues in addition to bone and/or cartilage. Alternatively, the present methods, compositions and devices make use of other naturally-occurring or biosynthetic proteins sharing a defined structural and functional relationship with OP-1 and thus appreciated herein also to function as tissue morphogens. Optionally, OP-1 or a related protein can be used alone or when adsorbed on a support matrix which provides an anchoring substratum for proliferation and/or differentiation of progenitor cells during tissue-specific morphogenesis. In another embodiment, OP-1 or a related protein is used to stimulate mammalian progenitor cells ex vivo, such that the stimulated cells, when disposed in vivo in a mammal, undergo tissue-specific morphogenesis to produce replacement tissue at a nonskeletal tissue locus in need thereof (i.e., at a nonbony or noncartilaginous tissue locus in need thereof).
    • 本发明提供用于在哺乳动物中诱导组织特异性再生或用于刺激哺乳动物祖细胞增殖的方法,组合物和装置。 本发明的方法,组合物和装置利用成骨蛋白1(OP-1),其在本文中被认为是组织形态发生体,即,除骨骼和/或骨骼之外还能够诱导哺乳动物身体组织的组织特异性形态发生的物质 软骨。 或者,本发明的方法,组合物和装置利用与OP-1共享定义的结构和功能关系的其它天然存在或生物合成蛋白,因此在本文中也可以用作组织形态发生剂。 任选地,OP-1或相关蛋白质可以单独使用或当被吸附在支持物基质上时,其在组织特异性形态发生过程中提供用于祖细胞增殖和/或分化的锚定底物。 在另一个实施方案中,OP-1或相关蛋白用于离体刺激哺乳动物祖细胞,使得当被哺乳动物体内植入时,被刺激的细胞经历组织特异性形态发生以在非骨骼组织基因座处产生替代组织 需要(即在有需要的非糖或非糖化组织位点)。
