Abstract
We show that a reflexive subspace of the predual of a von Neumann algebra embeds into a noncommutative -space for some . This is a noncommutative version of Rosenthal's result for commutative -spaces. Similarly for , an infinite-dimensional subspace of a noncommutative -space either contains or embeds in for some . The novelty in the noncommutative setting is a double-sided change of density
