从人单核细胞系THP-1中筛选出一株具有活化特性和独特形态的巨噬细胞系。最初的THP-1细胞在25cm2的培养瓶中培养了9年以上,然后出现了不同形态的细胞,附着在培养瓶的底部。在每一次传代培养中,通过丢弃漂浮的非贴壁细胞来选择这些细胞。在培养过程中,贴壁的THP-1细胞进行了长时间的浓缩。这些贴壁的THP-1不仅在形态上,而且在功能上都表现出显著的表型变化。也就是说,巨噬细胞吞噬活性、HLA-DR表达和MLR刺激活性均显著增强。这种贴壁细胞系被命名为激活的THP-1(A-THP-1),因为它表现出在没有外源刺激的情况下持续激活的巨噬细胞的特征。克隆的A-THP-1细胞株(A-THP-1C1)也具有相同的特征,含有约10%的多核巨细胞,可能是由细胞融合引起的。该A-THP-1细胞系是第一个被激活的巨噬细胞系,为了解巨噬细胞的激活机制和多核提供了一个很好的模型。本文对该细胞系的形态、免疫学和生物学特性进行了描述。
A new macrophage cell line with activated character and unique morphology was isolated by selecting adherent cells from the human monocytic cell line THP-1. The original THP-1 cells had been cultured for more than 9 years using 25 cm2 flasks, when cells with a different morphology appeared, adhering to the bottoms of the culture flasks. These were selected by discarding floating nonadherent cells at every subculture. Enrichment of adherent THP-1 cells with long processes proceeded during the cultivation. These adherent THP-1 showed remarkable phenotypic changes, not only morphologically, but also functionally. Namely, increased phagocytic activity, HLA-DR expression and MLR stimulator activity were remarkable. This adherent cell line was designated as activated-THP-1 (A-THP-1), since it demonstrated characteristics of activated macrophages continuously without exogenous stimulation. A cloned A-THP-1 cell line (A-THP-1 C1) also showed the same features and contained about 10% multinucleated giant cells probably caused by cell fusion. This A-THP-1 cell line, the first activated macrophage cell line to be established, provides a good model for understanding of activation mechanisms of macrophages and multinucleation. In this paper, morphological, immunological, and biological characters of this cell line are described.
