We have investigated the in vitro transformation of lymphocytes that have been frozen and stored at low temperatures. Cells frozen at different times and stored for various times do transform in a reproducible manner when placed in culture with PHA or as one population of the two-way or the one-way MLR. When frozen-stored lymphocytes are cultured with specific antigen or as both partners in the MLR the response is minimal. The freezing process destroys neutrophils, and the remaining population transforms in a manner similar to cultures of purified lymphocytes. Practical aspects of the technique are discussed and we have suggested possible practical applications for future investigation.
我们研究了在低温下冷冻保存的淋巴细胞的体外转化。在不同时间冷冻并保存不同时长的细胞,当与PHA一起培养时,或作为双向或单向混合淋巴细胞反应中的一个群体时,确实会以可重复的方式发生转化。当冷冻保存的淋巴细胞与特异性抗原一起培养时,或作为混合淋巴细胞反应中的双方时,反应极小。冷冻过程会破坏中性粒细胞,剩余的细胞群体转化方式与纯化淋巴细胞培养物相似。讨论了该技术的实际应用方面,并且我们提出了未来研究可能的实际应用。
