Stem Cell Related Patent Number US6565843

Title:Protein-induced tissue morphogenesis
Inventors:Cohen, Charles M.; Medway, MA, USA

Summary:Described herein is a method of morphogen-induced modulation of the inflammatory response. The invention relates to methods, compositions and devices for inducing tissue-specific regeneration in a mammal, or for stimulating the proliferation of mammalian progenitor cells. Further disclosed are ways in which osteogenic protein 1 (OP-1) is utilized as a tissue morphogen, that is, as a substance competent to induce tissue-specific morphogenesis of mammalian body tissues in addition to bone and/or cartilage. Several embodiments of the invention are provided, including one in which naturally-occurring or biosynthetic proteins are used in sharing a defined structural and functional relationship with OP-1 and also as tissue morphogens. Also provided are the means by which OP-1 or a related protein may be used alone or when adsorbed on a support matrix which provides an anchoring substratum for the proliferation or differentiation of progenitor cells during tissue-specific morphogenesis. The stimulation of mammalian progenitor cells ex vivo is further included, such that the stimulated cells, under specific conditions, exhibit tissue-specific morphogenesis to produce replacement tissue at a nonskeletal tissue locus such as at a nonbony or noncartilaginous tissue locus. Specific polypeptides are disclosed, as are therapeutic applications in the treatment of tissue damage, autoimmune diseases, diabetes, asthma, and ischemia reperfusion injury.
Abstract: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).
