Table 3. Percentages of secretory acinar marker-expressing cells throughout SMG development.

Single cell analysis data from the MxIF of the SMG developmental TMAs and overlays of statistical data onto the immunostains were used to calculate the percentages of total epithelial cells expressing the transient perinatal secretory protein, PSP, and the mature SMG secretory protein, MUC10, respectively, as shown in </emph>Fig. 4. Averages of three counts from three positions for each developmental stage are shown with standard deviations for total percent of cells positive for each marker alone and total percent positive for both makers. nd indicates not detected. Extensive co-expression of these secretory markers was revealed during the perinatal stages of development.
