Figure 3From: Identification of mesenchymal stem cells and osteogenic factors in bone marrow aspirate and peripheral blood for spinal fusion by flow cytometry and proteomic analysisAlkaline phosphatase (ALP) activity measurement. There was higher ALP activity in the induction medium culture than in the complete medium culture in both PB and BMA (t test, p < 0.01, n = 3). There were no significant differences in ALP activity between the PB and BMA in complete medium or induction medium culture in each time point shown (t test, p > 0.05, n = 3).Back to article page
