We see Kabuto pumping flesh from his attached snake into Sasuke, so most likely if Sasuke has Hashirama cells, then so does Kabuto. Which would be weird, since Kabuto only ever attributed his regenerative powers to Orochimaru and Karin's life forces, not Hashirama's. Then again, Yamato never displayed regeneration or enhanced stamina like other Hashi-transplantees (on the contrary, his stamina seems rather lousy) so who knows, it may not be an entirely automatic thing.

Thus making Kabuto Wolverine of the Naruto Universe.
