Life span elongation of Werner's syndrome fibroblasts by co-culture with origin-defective SV-40 DNA transformed cells.
Co-culturing with origin-defective SV40 DNA-injected transformants, we succeeded in activating the limited growth potential of late-phase-II fibroblasts from patients with Werner's syndrome (WS cells). Residual life spans of three WS cell lines increased 2.3-5.6 fold. Co-culture with normal IMR-90 cells showed variable effects on different WS cell lines.
