Table 3.
Summary of cNSC cochlear localization and protein expression. This table lists those markers that were expressed in transplanted cNSCs. In most cases, cNSCs had upregulated those markers that are expressed by endogenous cells of the microenvironment.

Key: (+) = immunohistochemistry positive; (-) = immunohistochemistry negative; (+/-) = in sections with positive calbindin labeling to endogenous cells, stem cells exhibited variable calbindin expression. Bold = immunolabeling not expected in endogenous tissue. (†)= could not determine expression due to lack of antibodies appropriate for paraffin sections
