图4 四种固定方法下的胎鼠肺支气管HE染色结果（×200） 注：A，直接取肺浸润组；B，气管内灌注后取肺浸润组；C，胎鼠整体浸润组；D，气管内灌注后胎鼠整体浸润组。绿色箭头指示为肺支气管；黑框指示被放大区域内为单层柱状上皮细胞；三角形处为肺组织内的血管。

Figure 4 Results of HE staining of fetal rat lung bronchi usng four fixation methods （×200） Note： A， direct lung infiltration group； B， lung infiltration group after intratracheal infusion； C， whole-body infiltration group of fetal rats； D， whole-body infiltration group after intratracheal infusion of fetal rats. The green arrows indicate bronchi of lung， the boxed areas highlight the monolayer columnar epithelial cells and the triangular regions indicate the blood vessels within the lung tissue.
