本文对本室建立的小鼠白血病病毒（ＭｕＬＶ）感染的ＳＲＳＶ一３Ｔ３细胞系与国际公认的Ｍｏｌｏｎｅｙ一ＭｕＬＶ感染的Ａ９细胞系间的Ｆｎ表达变化进行了比较研究。结果发现ＳＲＳＶ／３Ｔ３和Ａ９细胞表面的Ｆｎ荧光强度比正常成纤维细胞明显增强，并出现弥散分布的点状“强染点”，而在Ａ９和ＳＲＳＶ／３Ｔ３细胞的培养液中Ｆｎ含量却明显减少。
In this study, we compared the changes of Fn expression between the murine leukemia virus (MuLV) -infected SRSV-3T3 cell line and the internationally recognized Moloney-MuLV-infected A9 cell line established in our laboratory. The results showed that the Fn fluorescence intensity of SRSV / 3T3 and A9 cells was significantly higher than that of normal fibroblasts, and the dot-like “dyed spots” appeared diffusely distributed. However, the Fn content in the medium of A9 and SRSV / 3T3 cells was obviously cut back.
