Task: Answer Verification
Input (English): Question: Does neosquamous epithelium typically arise from Barrett 's epithelium?
Answer: Our mutational data support the hypothesis that, in most circumstances, NSE originates in cells different from those responsible for self-renewal of Barrett's epithelium. However, in one case, NSE and Barrett's epithelium seem to have arisen from a progenitor cell that was capable of differentiating into either intestinal metaplasia or NSE.
Output (English): no
