Ashura's power no longer rests in Hashirama, nor does it rest in his cells. According to Hagoromo, Hashirama and Madara were born with Ashura and Indra's powers respectively. When Madara took Hashirama's cells it gave him the Sage's powers. At this point Sasuke and Naruto are the only ones with the power of the Sage's sons.
