a Number of CFU-Hill’s colonies formed by sorted MNCs. b Percentage of CD34+ cells isolated from MNCs. 1.2-fold increase in visit 2. c, d Migration of CD34+ cells in response to SDF-1a (10 and 100 ng/mL); results are expressed as fluorescence ratio between cells exposed to the chemotactic factor and cells exposed to media that did not contain SDF1a as a chemotactic factor (control). 1.1 and 1.2-fold, increase in visit 2, respectively ns = not significant
