Changes in miRNA expression during BCD cell expansion in vitro.

<p>A. miRNA microarray analysis. Values represent the ratio between levels in expanded islet cells at passage 2 and isolated human islets. Data are mean of results from 2 donors. B. qRT-PCR analysis of RNA extracted from sorted GFP⁺ BCD cells at passage 2. Values are mean±SE, relative to islets (n = 3 donors). *p ≤0.05; **p≤0.01; ***p≤0.001.
