In addition, the expressions of mitochondrial fusion markers, phospho-dynamin 1-like protein (p-DRP1), mitofusin-1 (MFN1), and dynamin-like 120 kDa protein (OPA1) were significantly higher in CKD-MSCs compared to their expressions in healthy-MSCs (Figure 1G,H). Here, MFN1 is linked to chronic kidney disease.
