Randomized trial identifies SC1 for promoting self-renewal and pluripotency in embryonic stem cells, suggesting new applications for stem cell research.
Key Points
To identify small molecules that regulate the self-renewal of embryonic stem cells (ES cells).
Conducted a chemical library screen to discover small molecules affecting ES cell self-renewal.
Characterized SC1, a heterocyclic molecule that supports murine ES cells' undifferentiated state.
Evaluated the differentiation potential of SC1-expanded ES cells and their ability to contribute to chimeric mice.
SC1 effectively maintains murine ES cells in a pluripotent state without feeder cells, serum, or leukemia inhibitory factor.
Long-term SC1-expanded ES cells differentiated into all three primary germ layers in vitro.
SC1 demonstrated dual inhibition of RasGAP and ERK1.
