CD34 and hydrops fetalis: As was revealed in Figure 1C, both CD34 and αSMA expression level increased in the condition of HF, compared with that of normal conditions (the HF group: CD34: 1.71 ± 0.06, p < 0.05; αSMA: 2.59 ± 0.16, p < 0.05), and the application of CSWT exhibited reversed tendency in comparison with that of the HF group (CD34: 1.24 ± 0.08 vs. 1.71 ± 0.06, p < 0.05; αSMA: 1.19 ± 0.01 vs. 2.59 ± 0.16, p < 0.05).
