Additionally, the expression of HIF-1α/VEGF and the metastasis of breast cancer cells were induced via the downregulation of miR20b by ADSC-released stem cell factor (SCF), and this process was dependent on the activation of the c-Kit/p38-MAPK/E2F1 signaling pathway [184] (Figure 9). Here, KITLG is linked to breast carcinoma.
