Hmm i think a bit differently here.

I look up at vitality. Hashirama has strong chakra, mainly due to Ashura powers, but it grants him longer life as well. It is proven, that Hashi chakra extended life to Madara. That's something in common with Uzshiogakure. Second thing is, that Nagato wielded power of Rin'negan much more efficiently than Obito, who is Uchiha. This would confirm that Nagato has Senju cells, but it doesnt really confirm in what way. 3rd thing is that Ise (Nagato's father) doesnt really seem to be Senju, being in Amegakure. he might be senju, but it is unlikely.

Nagato is of Senju bloodline is what Madara said, so it could be from UZumaki and Senju bloodline. Uzumaki clan are something which will never be explained, but one thing is for sure. This one proves, that Uzumaki might be Ashura's descendants or at least part of it, because why would Uzumaki have RIkudou sealing jutsus?
