The present invention relates to methods of modulating mammalian stem cell and progenitor cell differentiation. The methods of the invention can be employed to regulate and control the differentiation and maturation of mammalian, particularly human stem cells along specific cell and tissue lineages. The methods of the invention relate to the use of certain small organic molecules to modulate the differentiation of stem or progenitor cell populations along specific cell and tissue lineages, and in particular, to the differentiation of embryonic-like stem cells originating from a postpartum placenta or for the differentiation of early progenitor cells to a granulocytic lineage. Finally, the invention relates to the use of such differentiated stem or progenitor cells in transplantation and other medical treatments.

Modulation of stem and progenitor cell differentiation, assays, and uses thereof

The present invention relates to methods of identifying modulators of angiogenesis utilizing human cells. The methods of the invention can be employed to assay compounds and small molecules for their ability to modulate human angiogenesis utilizing human pluripotent stem cells in an in vitro assay system. The present invention further relates to methods of identifying modulators of human angiogenesis by determining the ability of a test compound to modulate spontaneous vasogenesis in an in vitro assay system utilizing nonembryonic pluripotent stem cells. The present invention relates to in vitro assay systems utilizing nonembryonic pluripotent stem cells for the identification of compounds that modulate human angiogenesis or human vasogenesis. The present invention also relates to methods of treatment which require modulation of human angiogenesis or vasogenesis comprising administering to patients in need of such treatment compounds or small molecules which have been identified to be inhibitors of human angiogenesis or vasogenesis.

Methods for identification of modulators of angiogenesis, compounds discovered thereby, and methods of treatment using the compounds

This invention relates to new indole derivatives of formula (I), wherein R1 is hydrogen, halogen, nitro, carboxy, protected carboxy, acyl, etc., R2 is hydrogen, halogen, lower alkenyl, acyl, etc., R3 is lower alkenyl or lower alkyl, both of which are optionally substituted with aryl optionally substituted with one or more substituent(s) selected from the group consisting of halogen, aryl, lower alkoxy, etc., and R4 is carboxy, protected carboxy, acyl, etc., in addition to their significances above, R?1 and R2?, together with the carbon atoms to which they are attached, represent a 4- to 7-membered carboxylic ring optionally substituted with oxo, or its pharmaceutically acceptable salt, which is useful as a medicament; and to new use of cyclic nucleotide-PDE inhibitors.
