Quick answer

No, not in the immune sense. Autologous fat comes from the same person, so it carries no risk of immune rejection and no allergy or viral-transmission concerns. Some of the graft is still usually lost, because transferred fat has no blood supply at first and fat cells far from nearby tissue can die before new vessels form. Reviews report resorption of 25% to 80%, depending on technique and the recipient site.

Answer

Graft loss comes from lack of oxygen, not rejection. Experimental work shows that fat cells near the edge of a graft survive, while cells in the centre can die. Stromal cells in a middle zone can replace some of the dead fat cells.
