Figure 3

The comparison between results from previous and current studies. Data labeled as “Previous study” are the average concentration of MCP-1 solutions that were incubated at standard conditions for 6–24 hours, and subsequently stored at −81°C for one to four days. The concentration of MCP-1 solutions after stored at either standard conditions or −81°C for seven days is obtained from data in Figure 1 and presented as “Current study (37°C)” or “Curren t study (−81°C)”. Values are represented as mean ± S D, * p < 0.05 and ** p < 0.01 for difference in MCP-1 concentration.
