Tetramethylpyrazine/Ligustrazine Can Improve the Survival Rate of Adipose-Derived Stem Cell Transplantation
Background We aimed to study the effect of tetramethylpyrazine/ligustrazine ( TMP ) on the survival rate of adipose-derived stem cell (ADSC) transplantation . Methods Human ADSCs were cultured and subcultured. Detection of cell growth was performed using CCK8 kit. A total of 12 BALB/c nude mice including 4 groups (group 1: ADSC–hyaluronic acid [HA] + phosphate-buffered saline [PBS]; group 2: ADSC-HA + TMP injection; group 3: ADSC-HA + TMP soaking; group 4: ADSC-HA + TMP injection + TMP soaking) were used for the animal experiments. Furthermore, hematoxylin-eosin staining and oil red O staining were conducted for the frozen section from the animal tissues. Besides, RNA was extracted from the samples, and reverse transcriptase–polymerase chain reaction experiment was performed. At last, samples were detected using transmission electron microscope. Results Tetramethylpyrazine/ligustrazine resulted in significant increase for cell proliferation on the seventh day. It was easier to promote the growth of adipose cell after injection and soaking of TMP . Hematoxylin-eosin staining and oil red O stain showed that injection and soaking of TMP could significantly increase the size of fat. The relative expression of peroxisome proliferator–activated receptor γ, CCAAT/enhancer-binding protein α, and Alu in group 4 was significantly higher than that in other groups. Conclusions Tetramethylpyrazine/ligustrazine can improve the survival rate of ADSC transplantation . The possible mechanisms of it may be that TMP induces the expression of transcription factor associated with fat formation including peroxisome proliferator–activated receptor γ, CCAAT/enhancer-binding protein α, and Alu and then promotes the growth of adipose cell.
