Expression of podoplanin wasshowed in 54 (30.5 %) out of 177 CAFs’ populations studied inthe work of Yurugi et al. Interestingly, all podoplanin-positiveCAFs correlated with invasiveness of adenocarcinomas, whilea podoplanin-negative phenotype was shown only in noninvasiveadenocarcinomas (Yurugi et al., 2017). Here, PDPN is linked to adenocarcinoma.
