CDH1 and nasopharyngeal carcinoma: For example, hydrogel not only promotes NPC survival, but also maintains the stemness of NPC via the regulation of cadherin/β‐catenin signaling.27 Subsequently, we constructed cell lines that interfered with E‐cadherin and found that the pluripotency of ESCs on the RGO substrates is dependent on E‐cadherin.
