Muscle and lipid

From:Sylvia Poulos <>

One more puzzle for the pro's...

Has anyone stained for desmin and followed it up with OIl-Red-O?  I did so in cultured cells and the desmin staining is completely covered up by the Oil-Red-O.  My question is- are these fat cells that are desmin reactive?  are they muscle cells with large amounts of lipid?

Thanks again,
