The protein-bound polysaccharide preparation, PS-K, isolated from a mushroom, Coriolus versicolor, was found to stimulate human lymphocytes and induce them into blastogenesis in vitro. This stimulatory effect seemed to be nonspecific since lymphocytes from cord blood of newborn babies were also stimulated by PS-K. The highest lymphocyte blastogenesis by PS-K was observed after 5 days in culture.
从香菇云芝中分离出的蛋白结合多糖制剂PS-K，被发现能刺激人淋巴细胞并在体外诱导其发生细胞增殖。这种刺激作用似乎是非特异性的，因为新生婴儿脐带血中的淋巴细胞也受到PS-K的刺激。培养5天后观察到PS-K诱导的淋巴细胞增殖最为显著。
