Structure of recombinant retroviral vectors. Human full-sized, nonspliced type WT1 cDNA with or without the deletion of the third domain of zinc finger region was inserted into a pM5GNeo retroviral vector. The solid bar within WT1 cDNA represents the deleted region of mutant WT1. K, Kpn I; E, EcoRI; H,HindIII.
