Sprouty (Spry) genes encode negative regulators of receptor tyrosine kinase (RTK) signaling, which plays important roles in human embryonic stem cells (hESCs). SPRY2 and SPRY4 are the two most highly expressed Sprouty family members in hESCs, suggesting that they may influence self-renewal. To test this hypothesis, we performed siRNA-mediated knock down (KD) studies. SPRY2 KD resulted in increased cell death and decreased proliferation, whereas SPRY4 KD enhanced survival. In both cases, after KD ...[more]
