From: Salidroside attenuates hypoxia-induced pulmonary arterial smooth muscle cell proliferation and apoptosis resistance by upregulating autophagy through the AMPK-mTOR-ULK1 pathway

Fig. 4

Increased numbers of autophagosomes may be related to salidroside-induced decreases in the proliferation and increases in the apoptosis of PASMCs under hypoxic conditions. Images of autophagosomes in PASMCs of each group acquired by Hitachi H-600 transmission electron microscopy. The control group exhibited less autophagosomes than the hypoxia group. The salidroside group exhibit increased numbers of autophagosomes than the hypoxia group. Red arrow: autophagosomes
