LEP and skin basal cell carcinoma: BCCs incubated in control shRNA obASCs induced BCC proliferation by 1.4-fold in MCF7 cells, 1.8-fold in ZR75 cells, and 1.6-fold in T47D cells; however BCCs incubated in control shRNA lnASCs, leptin shRNA lnASCs, and leptin shRNA obASCs were unable to induce BCC proliferation.
