Experimental Protocol


BM-MSC and ASC cultures were established from 3 mouse strains: (a) WT, (b) p53loxP/loxP and (c) p53loxP/loxP RbloxP/loxP. The corresponding mutant cells were generated by excision of the LoxP-flanked sequences by infection of all MSC cultures with adenoviral vectors expressing the Cre-recombinase gene (Ad-CMV-Cre). NSG mice were inoculated subcutaneously with 5×10^6 mutant cells. Animals were killed when tumors reached 1 cm3 or 150 days after infusion. Some of the obtained tumors were mechanically disaggregated to establish ex vivo MSC-transformed cell lines. Gene expression analysis was performed using BM-MSCs and ASCs from all genotypes, as well as tumor cell lines derived from p53-/- and p53-/-Rb-/- BM-MSC and ASC cultures.
