以人胚肺二倍体成纤维细胞为实验模型，观察洋参果口服液对体外培养细胞寿命的影响，实验结果显示洋参果口服液可以提高人胚肺成纤维细胞增殖期群体倍增水平，延长细胞传代无数，延缓衰老细胞群体死亡的发生，从而延长衰老的人胚肺成纤维细胞的体外传代寿命。
Human embryonic lung diploid fibroblasts were used as experimental models to observe the effects of oral administration of ginseng extract on the cell life in vitro. The results showed that the oral administration of ginseng extract could increase the doubling level of human embryo lung fibroblasts in the proliferative phase, Prolong the numerous cell passages, delay the death of the aging cell population, and prolong the passage life of aging human embryonic lung fibroblasts in vitro.
