Viability and proliferation rate of ASCs cultured with serum and without serum in both 21 % O2 and 2 % O2. a ASCs cultured with serum had higher viability as compared to those cultured without serum in both 21 % O2 and 2 % O2. ASCs cultured without serum in 2 % O2 had higher viability as compared to those cultured without serum in 21 % O2. b ASCs cultured with serum in 2 % O2 had the highest number of cells as compared to ASCs in other conditions. At day 7, ASCs cultured without serum in 2 % O2 showed a significant (p < 0.05) increase in cell number as compared to ASCs cultured without serum in 21 % O2. *p < 0.05 relative to 21 % O2 without serum; #p < 0.05 relative to 2 % O2 without serum
