Identification and differentiation of PDX1 β-cell progenitors within the human pancreatic epithelium

Table 2 Preservation of epithelial cells during culture in a defined epithelial medium

Condition	Percent positive
	Vimentin	EpCAM
Epithelial Medium (n = 7)	44.87 ± 4.93b	24.10 ± 8.60
MSC Medium (n = 3)	95.67 ± 1.36b	17.43 ± 6.88

Data represent means ± SE. Statistical analysis of the differences between the groups was calculated with STATA11 (StataCorp LP, College Station, TX) using one-way analysis of variance and Bonferroni post-hoc test.

^bP < 0.01 for vimentin positive cells expanded in epithelial medium vs MSC medium. EpCAM: Epithelial cell adhesion molecule; MSC: Mesenchymal stem cell.
