Salivary phenotypic marker and stem cell
marker changes at the
protein level after organization induction. The protein translation
of the salivary epithelial (α-amylase, AQP5, E-cadherin, ZO-1,
CK7, and CK18) or stem cell-related (OCT4, SOX2, NANOG, LGR5, CD90,
and KRT5) markers was examined by Western blot, and the expression
levels relative to β-actin were calculated. The data from three
independent experiments were analyzed and presented as the mean ±
standard errors of the mean (n = 3). One-way ANOVA,
Tukey’s post hoc test. *, compared with 2D plastic; #, compared
with floating culture; $, compared with Matrigel. ***P < 0.001, #P < 0.05, ##P < 0.01, ###P <
0.001, $P < 0.05, $$P < 0.01.
