摘要:
The present invention provides compositions and methods to facilitate the identification of compounds that are capable of interacting with a biological macromolecule of interest. In one aspect, a composition is provided that comprises an array of one or more types of chemical compounds attached to a solid support, wherein the density of the array of compounds is at least 1000 spots per cm2. In particularly preferred embodiments, these compounds are attached to the solid support through a covalent interaction. In general, these inventive arrays are generated by: (1) providing a solid support, wherein said solid support is functionalized with a selected chemical moiety capable of interacting with a desired chemical compound to form an attachment; (2) providing one or more solutions of one or more types of compounds to be attached to the solid support; and (3) delivering said one or more types of compounds to the solid support, whereby an array is formed and the array of compounds has a density of at least 1000 spots per cm2. In another aspect, the present invention provides methods for utilizing these arrays to identify small molecule partners for biological macromolecules of interest comprising: (1) providing an array of compounds, wherein the array has a density of at least 1000 spots per cm2; (2) contacting the array with one of more types of biological macromolecules of interest; and (3) determining the interaction of specific small molecule-biological macromolecule partners.

摘要:
Certain embodiments disclosed herein are directed to a method of producing endoderm cells, such as definitive endoderm cells by exposing stem cells such as embryonic stem cells or induced pluripotent stem (iPS) cells to an effective amount of at least one compound described herein to differentiate the stem cells into the endoderm cells such as definitive endoderm cells. Differentated endoderm cells produced by the methods disclosed herein can be differentiated into pancreatic epithelium, and other endoderm derivatives such as thymus, liver, stomach, intestine and lung. Another aspect of the present invention relates to a method of producing pancreatic progenitor cells, such as Pdx1-positive pancreatic progenitor cells by exposing endoderm cells, such as definitive endoderm cells to an effective amount of at least one compound described herein to differentiate the definitive endoderm cells into Pdx1-positive pancreatic progenitor cells. Kits and compositions comprising Pdx1-positive pancreatic progenitor produced using the methods are also described.
