They're definitely not transplants.. and Oro said the KKG/DNA was not rejected.. hence it became part of Shin. He then awakened his own Sharingan, and I'm guessing Itachi's death caused him to awaken his own Mangekyo and fall into the curse of hatred that lies in the DNA, which is why Danzo's right arm did not have Shin's Mangekyo because Shin awakened it afterwards. It is most definitely part of the DNA now. They are exactly as Oro called them, false Uchiha.
