    摘要: The present invention relates to methods based on the interactions of thrombin as a biological regulator. More specifically, the invention relates to the interactions of thrombin with regard to Notch signaling, Jagged1, PAR1, and cellular effects mediated thereby. The invention relates to the discovery that thrombin cleaves Jagged1 to produce non-membrane soluble Jagged1 (sJ1). The soluble Jagged1 protein can affect Notch signaling and, among other things, mediate the release of FGF-1 and/or IL-1α from a cell. The invention further relates to the role(s) of thrombin and signaling via Notch proteins and the effect on thrombosis, angiogenesis, and/or differentiation, among other processes. Moreover, the invention relates to discovery that thrombin, sJ1, and TRAP mediate, inter alia, rapid non-classical release of FGF-1, and proteins associated therewith (e.g., p40 Syn1 and S100A13, among others), and the effect growth and proliferation of a stem cell without loss of differentiation potential. Thus, the present invention relates to methods of clonally expanding a pluripotent stem cell while preserving the differentiation potential of the cell, a process termed “stamatogenesis.”

    摘要: The invention relates to a novel CTHRC1 nucleic acid and protein encoded thereby. Expression of CTHRC1 is induced by injury in, among others, arteries and skin, and CTHRC1 is expressed in bone, cartilage, kidney, lung and brain. CTHRC1 expression is associated with collagen matrix production, arterial remodeling, arterial restenosis, constrictive remodeling, vessel injury, ectopic ossification, fibrosis, and the like. CTHRC1 also plays a role in cell-cell and cell-matrix adhesion, cell-migration, and bone, cartilage, skin and brain development. CTHRC1 also regulates the level of BMPs, including BMP1 and BMP4, and the invention encompasses methods relating to affecting the level of BMPs by affecting the level of CTHRC1. In addition, the invention relates to modulation of the level of CTHRC1 to affect processes associated with fibrosis mediated by formation of collagen matrix. The invention further relates to methods of treating, preventing, and/or detecting these diseases, disorders or conditions, where the methods comprise modulating or detecting CTHRC1 expression and/or production of CTHRC1 polypeptide. The invention also relates to affecting CTHRC1 expression using cytokines.
