Immunophenotypical characterization of ASCs cultured in tPR. Passage 2 ASCs grown in tPR were positive for CD73 and CD90, mesenchymal stem cell markers, and were negative for CD34, a hematopoietic stem cell marker not typically found on passaged mesenchymal stem cells [25]. Black and red histograms represent specific and control antibody staining, respectively.
