Stemolecule™ Doxycycline hyclate (Dox), a derivative of tetracycline, is used to induce expression of the Stemgent® iPSC Generation Dox Inducible products. In the iPSC Generation Dox Inducible protocol, addition of Dox to the culture medium of transduced cells induces the reverse tetracycline transactivator (rtTA) to bind to the Tet response element and results in the transcriptional activation for each of the factors implicated in the reprogramming process. Conversely, Dox can be removed from the medium to suppress transcriptional activation of the reprogramming factors.

Stemolecule™ Cyclopamine , Cat. No. 04-0022
Stemolecule™ Cyclopamine has been identified as a specific inhibitor of hedgehog singaling by direct binding to the heptahelical bundle of Smoothened. Hedgehog signaling is involved in embryogenesis as well as cancer progression. Cyclopamine has been utilized as a small molecule inducer of stem cell differentiation towards definitive endoderm pancreatic islet cells, as a modulator of cell proliferation, and as an anticancer drug.
Stemolecule™ All-Trans Retinoic Acid , Cat. No. 04-0021
Stemolecule™ All-Trans Retinoic Acid functions as a signaling molecule for various developmental pathways that control differentiation and proliferation. It has been used in various differentiation protocols, including B-cells, T cells and neurons, and implicated in specification of the embryonic anterior/posterior axis through Hox gene regulation.
Stemolecule™ KAAD-Cyclopamine , Cat. No. 04-0028
Stemolecule™ KAAD-Cyclopamine is a sonic hedgehog antagonist known to target Smoothened. Hedgehog signaling is involved in embryogenesis as well as cancer progression. KAAD-Cyclopamine has been utilized to halt the migration or proliferation of a variety of cancer cells.
iPSC Generation
Stemolecule™ Tranylcypromine hydrochloride , Cat. No. 04-0033
Stemolecule™ Tranylcypromine inhibits BHC110/LSD1, a histone H3 lysine 4 demethylation enzyme with close homology to monoamine oxidases. Treatment of P19 embryonal carcinoma cells with tranylcypromine resulted in global increase in H3K4 methylation as well as transcriptional derepression of the pluripotent stem cell marker Oct4.
