Task: Answer Verification
Input (English): Question: Do reactive oxygen species regulate the quiescence of CD34-positive cells derived from human embryonic stem cells?
Answer: This study reveals that NOX4 produces ROS in CD34(+) cells during vascular differentiation of hESCs, and shows that modulation of ROS levels using antioxidants such as selenium may be a novel approach to increase the vascular differentiation efficiency of hESCs.
Output (English): yes
