The results of the RNA sequencing data (GSE138435 and reference, Sandiford et al., 2021) of the purified MVs identified increased levels of 12 of the 17 secreted CanCord34 genes (including the EXOSC4 and PUF60 mRNAs) in the primed MVs secreted by MSCs which were exposed to breast cancer cells (Figure 6C,D). Here, EXOSC4 is linked to breast carcinoma.
