Analysis of MSC proliferation at passages 3 and 7. (A) The percentage of EdU-positive cells was determined for four different donors after both 6 and 18 hours at passages 3 and 7 (EdU, green;, nuclei, blue). (B) A paired t test indicated a statistically significant difference (P < 0.05) between passages 3 and 7 for EdU-positive expression at 6 hours. (C) A paired t test indicated a statistically significant difference between passages 3 and 7 for EdU-positive expression at 18 hours.
