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.
