Changes in the numbers of different types of cells before and after filtration and the quantitative distribution of these cells in the composite. a–d Changes in the number of RBCs, WBCs, PLs, and MSCs (CFU/ALP+) in bone marrow before and after filtration; e the enrichment efficiency of RBCs, WBCs, PLs, and MSCs after filtration; f–h the difference in the numbers of other types of cells (RBCs, WBCs, or PLs) normalized to that of the respective MSCs in the original bone marrow and postfiltration composite biomaterial; i the arrow-connected blue and red balls, respectively, represent the quantitative distribution of RBCs, WBCs, and PLs corresponding with each MSC in original bone marrow (blue balls) and in the filtered composite material (red balls) from the same volunteer
