ID-8 --- DYRK Inhibitor

ID-8 is a highly potent and selective small molecule inhibitor of dual-specificity tyrosine phosphorylation-regulated kinase (DYRK). It could support Wnt-induced human embryonic stem cell proliferation and survival without differentiation. Using ID-8, a novel and simple chemically defined xeno-free culture system was developed that allows for long-term expansion of human pluripotent stem cells without FGF or TGF-beta pathway activation. These culture conditions do not include xenobiotic supplements, serum, serum replacement, or albumin. Using this culture system, several human pluripotent cell lines maintained pluripotency (>20 passages) and a normal karyotype and still retained the ability to differentiate into derivatives of all three germ layers. This Wnt-dependent culture system should provide a platform for complete replacement of growth factors with chemical compounds.

How to use

In Vitro:

ID-8 was used at 0.5 µM final concentration in cell culture. D-8 (0.1-10 μM) increases human embryonic stem cell (hESC) survival. ID-8 (10 μM) stimulates ESCs proliferation in serum-free media for more than 1 month.
