Indazole-3-carboxamide compounds for treating various diseases and pathologies are disclosed. More particularly, the present invention concerns the use of an indazole-3-carboxamide compound or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as genetic diseases and neurological conditions/disorders/diseases due to mutations or dysregulation of the Wnt pathway and/or of one or more of Wnt signaling components.

Methods and compositions are provided for the identification of stem cells and cancer stem cells. β-catenin is also identified as a target for the development of therapeutic moieties against hematopoietic tumors, i.e. leukemia and lymphoma cells, which may include screening assays directed at β-catenin, or members of the β-catenin signaling pathway. Cellular proliferation in hematopoietic cells can be altered by introducing stabilized β-catenin into a hematopoietic cell that is altered in its ability to undergo apoptosis but which is not fully transformed. The immortalized cells are useful in screening assays, and in the analysis of pathways by which hematopoietic cells undergo transformation.

Methods for generating high-yield, high-purity cardiomyocyte progenitors or cardiomyocytes from pluripotent cells are described. Wnt/β-catenin signaling is first activated in pluripotent cells, e.g., by inhibition of Gsk-3 to obtain a first population of cells. Wnt/β-catenin signaling is then inhibited in the first cell population to induce cardiogenesis under fully defined, growth factor free culture conditions.

It has been demanded to improve the poor solubility of curcumin to develop an anti-tumor compound capable of inhibiting the growth of various cancer cells at a low concentration. Thus, disclosed is a novel synthetic compound, a bis(arylmethylidene)acetone, which has both of an excellent anti-tumor activity and a chemo-preventive activity. A bis(arylmethylidene)acetone (i.e., a derivative having a curcumin skeleton) which is an anti-tumor compound and has a chemo-preventive activity is synthesized and screened. A derivative having enhanced anti-tumor activity and chemo-preventive activity can be synthesized.

Methods for generating high-yield, high-purity cardiomyocyte progenitors or cardiomyocytes from pluripotent cells are described. Wnt/β-catenin signaling is first activated in pluripotent cells, by, for example, inhibiting Gsk-3 to obtain a first population of cells. Wnt/β-catenin signaling is then inhibited in the first cell population to induce cardiogenesis. One or more of these steps is performed under defined, albumin-free culture conditions.
