Combined treatments of hbl cells with cisplatin and SAHA eliminate CAFs, while neuron-like cells are not eliminated, but are growth-arrested. Cells were plated at high density and treated for 48 h. (A) Images of hbl74, hbl75 and hbl92 cells treated with DMSO, cisplatin, SAHA and cis+SAHA. Scale bars are identical for all images and are shown for the plated cells. (B) Counting of hbl74 and hbl75 cells after treatments. ** shows p < 0.01, **** shows p < 0.0001. NS—not significant. (C) Western Blot of proteins isolated from experimental plates of hbl74 and hbl75. (D) Western Blot of proteins isolated from experimental plates of hbl92. (E) A summary of studies of hbl cells treated with cisplatin and SAHA. The whole gel images of western blots can be found in File S1.
