生物活性:
L-Tryptophan (Tryptophan) is an orally active and essential amino acid that is the precursor of serotonin, melatonin, and vitamin B3. L-Tryptophan can promote an increase in stemness and osteogenic ability of BMSCs in vitro and in vivo. L-Tryptophan inhibits cell proliferation and induced cell cycle arrest with high levels.
体内研究:
L-Tryptophan (Tryptophan;10、50 kg/mg/天;腹膜内注射;连续三周) 以 50 mg/kg/天可增强 mBMSC 体内的迁移、集落形成和成骨分化。L-Tryptophan (50 毫克/公斤/天;腹腔注射;连续三周) 加速小鼠股骨手术缺损的骨再生。Animal Model:Five-week-old C57BL/6 mice
Dosage:10, 50 kg/mg
Administration:Intraperitoneally; daily; for consecutive three weeks
Result:The concentration of 50 mg/kg/day induced a significant increase in the number of SSEA-4 positive cells. Increased the mRNA levels of Nanog and Oct-4 and the colony-forming ability of mBMSCs with 50 mg/kg/day.
体外研究:
L-Tryptophan (Tryptophan;500、1000 μM;48 小时) 高剂量下可显着抑制 pTr2 细胞增殖并增加细胞周期 G1 期的细胞百分比。L-Tryptophan (10 μM;持续三周) 增强 hBMSC 的体外迁移、集落形成和成骨分化。L-Tryptophan (10 μM;持续三周) 降低脂肪形成标志物 PPARγ 和 LPL 的 mRNA 水平。
