Among MCL-specific genes, several lines of evidence suggest an important role that Cdh1 encoding E-cadherin 1 may play in postnatal migration of Sox2/S100b cells in parenchyma (Fauquier et al., 2008, Lamouille et al., 2014, Batchuluun et al., 2017, Fujiwara et al., 2020). Here, SOX2 is linked to mantle cell lymphoma.
