Schwann cell purity and yield after two rounds of purification. aP < 0.05, vs. collagenase group.
(A) The cell yield per flask was significantly higher in the dispase group when compared with the collagenase group at each time point after purification (P < 0.05). 48 hours: the first round of purification; 96 hours: the second round of purification.
(B)There was a significant difference in cell purity between the two groups after the first round of purification (at 72 hours; P < 0.05), but no significant difference was found after the second round of purification (at 120 hours; P > 0.05).
