TGFB1 and esophageal squamous cell carcinoma: Results of Figure 1B, C, and F showed that the level of αSMA was evidently upregulated in adipose‐derived MSCs following incubation with the CM from KYSE30, KYSE410, KYSE510, or primary ESCC cells (Figure 1B and C), and IL‐6, IL‐7, IL‐8, CCL5, and TGF‐β1 were strongly secreted from adipose‐derived MSCs incubated with the CM from these indicated ESCC cells (Figure 1F).
