Biological Activity
PluriSln 1 is an inhibitor of stearoyl-coA desaturase (SCD), and is a pluripotent cell-specific inhibitor.
In Vitro
PluriSln 1, a small-molecule inhibitor of stearoyl-coA desaturase (SCD), on induced pluripotent stem cells (iPS)-derived cardiomyocytes (CM). PluriSln 1 treatment significantly decreases the mRNA and protein level of Nanog, a marker for both cell pluripotency and tumor progression; importantly, we provide evidence that PluriSln 1 treatment at 20 µM for 1 day significantly induces the apoptosis of Nanog-positive iPS derivates (iPSD). In addition, PluriSln 1 treatment at 20 µM for 4 days diminished Nanog-positive stem cells in cultured iPSD while not increasing apoptosis of iPS-derived CM. To investigate whether PluriSln 1 treatment prevents tumorigenicity of iPSD after cell transplantation, we intramyocardially injected PluriSln 1- or DMSO-treated iPSD in a mouse model of myocardial infarction (MI). DMSO-treated iPSD readily formed Nanog-expressing tumors 2 weeks after injection, which is prevented by treatment with PluriSln 1. Moreover, treatment with PluriSln 1 does not change the expression of cTnI, α-MHC, or MLC-2v, markers of cardiac differentiation (P>0.05, n=4). Importantly, PluriSln 1-treated iPS-derived CM exhibits the ability to engraft and survive in the infarcted myocardium[1].
