Described herein are methods and compositions relating to expanding, enriching, and/or maintaining a population of hematopoietic stem cells ex vivo. In some embodiments, the methods and compositions can relate to a combination of two or more agents, e.g., an agent that increases the expression of a Notch target gene; an agent that activates a ubiquitin ligase complex comprising cereblon; a compound that inhibits BMP signaling; a modulator of histone methylation; an inhibitor of TGFβ signaling; an inhibitor of p38 signaling; an activator of canonical Wnt signaling; a modulator of histone acetylation; a compound represented by formula (1); an aryl hydrocarbon receptor inhibitor; a histone demethylase inhibitor; a TGFβ receptor inhibitor; a compound that inhibits a protein that propagates p38 signaling; a compound that inhibits a protein that promotes β-catenin degradation; a histone deacetylase inhibitor; Prostaglandin; an agonist of Notch signaling; an inhibitor of SIRT1; UM171; and/or a compound listed in Table 1. |
