Percentages of epithelial cells retrieved from different isolation protocols.

<p>Mean percentages (± standard deviation) of isolated cytokeratin (CK)+ CD45− cells from jejunum either after DTT, EDTA or collagenase treatment with or without prior DTT wash (as discussed in details in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030247#pone-0030247-g001" target="_blank">Figs. 1</a> & <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030247#pone-0030247-g002" target="_blank">2</a>) are shown from uninfected normal healthy rhesus macaques (n = 5). Note that there was increased yield of ECs either by DTT or EDTA only treatment compared to other protocols followed in this experiment. Statistical significant differences between each group of cells are shown. * Indicates significant differences in ECs isolated from either DTT or EDTA only treatment compared to other group of cells.
