2. O9-1 细胞分化

图 1:成骨细胞标志物骨钙素 (Ocn) 的免疫荧光染色表明 O9-1 细胞在成骨分化条件下产生成骨细胞。细胞用成骨细胞标志物 Ocn 抗体 (绿色) 染色,细胞核用 DAPI (蓝色) 染色。箭头表示 Ocn 阳性细胞。骨钙素(Ocn,一种成骨细胞标志物);DAPI (′,6-二脒基-2-苯基吲哚)。

图 2:平滑肌肌动蛋白 (SMA) 的免疫荧光染色表明,在平滑肌细胞分化条件下,大多数野生型 O9-1 细胞产生平滑肌细胞 (A),而 Yap-null O9-1 细胞未能分化为平滑肌细胞 (B)。细胞用 SMA 抗体(红色)染色,细胞核用 DAPI(蓝色)染色。箭头表示 SMA 阳性细胞。
