小鼠腫瘤接種模型，時間一般持續2-3周。如何使用氯膦酸二鈉脂質體清除小鼠腫瘤模型巨噬細胞？對于這種時間長的疾病模型，小鼠的狀態，小鼠的存活，比清除效果更為重要。兩者的平衡或者偏向，需要動態調整。
如下這篇Nature Communications，使用荷蘭Liposoma品牌巨噬細胞清除劑氯膦酸二鈉脂質體：Clodronate Liposomes&Control Liposomes。小鼠疾病模型：LLC肺癌模型。LLC細胞全稱為Lewis肺癌細胞（Lewis Lung Carcinoma），是一種來源于小鼠的肺癌細胞系，常用于癌癥研究的動物模型中。它并非人類肺癌的臨床分型，而是實驗室中用于模擬肺癌生長、轉移及藥物測試的模型工具。腹腔注射200ul，在腫瘤細胞接種后第7天，11天，15天腹腔注射荷蘭Liposoma品牌巨噬細胞清除劑氯膦酸二鈉脂質體：Clodronate Liposomes&Control Liposomes（CP-005-005）。

Liposoma巨噬細胞清除劑Clodronate Liposomes氯膦酸二鈉脂質體的材料和方法：
In other experiments, wildtype female C57BL6 or Mlck210?/? mice in the C57BL6 background bearing LLC tumors (n?=?6–8) were treated with daily i.p. injections of 1?mg clodronate or control liposomes (Liposoma Research Liposomes # CP-005-005) in 200?µl on day 7,11 and 15 after tumor inoculation. Tumors dimensions were recorded at regular intervals, typically every 1–2 days. Tumors were excised at 18 days after implantation and tumors, spleens and livers were excised for further analysis by flow cytometry. Alternatively, WT and Mlck210?/? C57Bl6 male mice bearing HPV+ MEER tumors (n?=?8–11) were treated with i.p. injections of 100?µg anti-CD8 antibodies (BioXcell In Vivo Plus Clone YTS 169.4, #BE0117) or saline on days 27, 29, 32, 41, and 44 after tumor inoculation. Tumor volumes were measured every 2–3 days. Tumors and spleens were harvested on day 48 after tumor inoculation for flow cytometry analysis.
