Per my comments on DMSO in terms of carcinogenesis, teratogenesis, etc.: Perhaps I should have been more specific. It is possible that any such activity attributed to DMSO is a function of the compounds ability to act as a carrier for almost anything. In many instances, substances that can't be solubilized in aqueous media are readily soluble in DMSO. It is a fantastic vehicle for solubilization. In part, that is the problem. As such any potentially carcinogenic agent is readily delivered by DMSO. However, it is also very likely that DMSO may indeed have carcinogenic properties. In biological systems, DMSO is used as a lipid/membrane modifying agent. It will easily alter membrane function, protein distribution, etc. As such, it is not surprising that the agent could cause genetic alterations at the cellular level (ie. via nuclear membrane modification). Also, it should be noted that in experimental settings, DMSO is actually used *because* of it's ability to transform cells, for example, as a differentiating agent for myeloblastoid cell types (U937 cell lines) to force polymorphonuclear leukocyte-like cell type formation. In essence, some of the commentary I've heard is that DMSO is currently considered much as compounds like acetone used to be.....no real hazard. The reality has become somewhat different.
