Abstract:

BACKGROUND: Different local anesthetic solutions for tumescent liposuction are necessary and have a certain effect on the biological characteristics of human adipose stem cells.
OBJECTIVE: To explore the effect of different tumescent local anesthesia on the proliferation and differentiation of human adipose stem cells cultured in vitro.
METHODS: Passage 3 human adipose stem cells were intervened by different tumescent local anesthesia (bupivacaine, ropivacaine, lidocaine). Cells cultured in low-glucose DMEM served as controls. Proliferation ability, lactate dehydrogenase activity in the supernatant and percentage of cells under adipogenic differentiation were detected.
RESULTS AND CONCLUSION: After intervention for 1, 2, 3, 4, 5 days, the supernatant lactate dehydrogenase activity in the bupivacaine, ropivacaine, lidocaine groups was significantly higher than that in the control group (P < 0.05), and moreover, the lactate dehydrogenase activity in the bupivacaine group was significantly higher than that in the ropivacaine group and lidocaine group (P < 0.05). The absorbance value of human adipose stem cells was lower in the bupivacaine, ropivacaine, lidocaine groups than the control group (P < 0.05) as well as lower in the bupivacaine group than the ropivacaine and lidocaine groups (P < 0.05). There was no significant difference in the percentage of cells under adipogenic differentiation between groups (P > 0.05). Overall, these findings indicate that different tumescent local anesthesia (bupivacaine, ropivacaine, lidocaine) can all inhibit the 
proliferation of human adipose stem cells, but have no certain effects on the adipogenic differentiation.
