Actually DMSO is not too bad. I believe that it is sometimes used to administer drugs through the skin! So....if it does dissolve in DMSO, don't spill the stuff on your skin!!
DMSO is used in cell culture to help cells survive cryopreservation. It also in some cases promotes growth and protein production in certain mammalian cells in bioreactors, FWIW.
