PRRT2 and alkaline phosphatase measurement: Upon closer examination, while hsa-miR-205 was most associated with all three HaCaT-derived EV types (Figure 1A–C), hsa-miR-21, hsa-miR-22, hsa-miR-143, hsa-miR-203, hsa-miR-10b and hsa-miR-205 exhibited the greatest eigenvector values in the PKC-derived AP populations (Figure 1A).
