CTRL and posterior cortical atrophy: Using our established PCa mouse model, we found that CAFs isolated from dCKO (PB‐Cre; Ptenflox/flox; Hic1flox/flox) mice[27] induced greater Treg differentiation than those isolated from Ctrl (PB‐Cre; Ptenflox/flox) mice (Figure 7K–L; Figure S13F, Supporting Information).
