Furthermore, the expression of cytokeratin in the RT+HF group and RT+SB group was enhanced compared to the RT group; the expression of mesenchymal markers vimentin was enhanced in the RT group compared to the NC group, but its expression was reduced in the HF group compared to the NC group, and its expression in the RT+HF group and RT+SB group was reduced compared to the RT group (Figure 3). Here, VIM is linked to hydrops fetalis.
