Figure 1.
The number of colony-forming units expressing alkaline phosphatase activity (ALP + CFU) in pre- and post-SECCS bone marrow. (A) The number of MSCs (ALP + CFU) in pre-SECCS bone marrow was significantly higher than that in post-SECCS bone marrow (Z = −5.646, P = 0.000). (B) For each patient, the number of MSCs (ALP + CFU) in pre-SECCS bone marrow was higher than that in post-SECCS bone marrow. The mean decrease was 203.19 ± 117.13/mL. SECCS: screen–enrich–combine(-biomaterials) circulating system; MSCs: mesenchymal stem cells; ALP + CFU: colony-forming units expressing alkaline phosphatase activity; Difference: difference between pre- and post-SECCS ALP + CFU.
