A small percentage of normal mouse thymus and spleen lymphocytes form rosettes with autologous erythrocytes. The number of these autologous rosettes increases 15- to 20-fold after adult thymectomy and to a lesser degree with aging. Autologous rosette level is also abnormally high in nude (congenitally athymic) mice. The high level of autologous rosette-forming cells found after adult thymectomy is normalized by injecting ng amounts of purified circulating thymic factor. Autologous rosette-forming cells adhere to nylon, belong to the less dense spleen cells, are in majority steroid-resistant in the thymus. All these properties suggest that autologous rosette-forming cells might belong to immature T-cell (thymic-dependent cell) precursors.
一小部分正常小鼠的胸腺和脾淋巴细胞能与自体红细胞形成玫瑰花结。成年胸腺切除术后,这些自体玫瑰花结的数量增加15至20倍,随着年龄增长增加幅度较小。裸鼠(先天性无胸腺)的自体玫瑰花结水平也异常高。成年胸腺切除术后发现的高水平自体玫瑰花结形成细胞,通过注射纳克量的纯化循环胸腺因子可恢复正常。自体玫瑰花结形成细胞能黏附于尼龙,属于密度较低的脾细胞,在胸腺中大多数对类固醇有抗性。所有这些特性表明,自体玫瑰花结形成细胞可能属于未成熟的T细胞(胸腺依赖性细胞)前体。
