DFUFs and DFFs produced and assembled less ECM than NFFs. Representative H&E stained sections of ECM tissues created by DFUF1, DFF6, or NFF10 are shown. Scale bars, 100 μm. Quantification of mean ECM area normalized to tissue length and cell number±SD (n=3). NFF10-produced ECMs were substantially thicker than those produced by either DFUF1 or DFF6. **p<0.01.
