</p><p>The Databook states anyone integrated with the cells of Hashirama have his regeneration. As far as I am aware, the arm is made of his DNA. That is why Naruto is listed as a user of his regeneration on the
Regeneration Ability page. Therefore, Naruto is affected by the arm and proves that it is mostly organic. Why else would Hashirama's cells be involved? How else can Naruto maneuver every finger?
</p><p>Why does it matter if Naruto's hand can be detached or not? It's still made of Hashirama's cells. He still is listed as being affected by it. He still is connected to it.
</p><p>The community isn't even sure if what Naruto had was detachable like Momoshiki's Prototype and he could have ripped it off, tried the prototype and got a new one or reattached it like how Madara reattached a random Zetsu hand.
</p><p>What we know is the previous arm was made of Hashirama's cells and that Naruto was given regeneration because of it due to the Databook.
