Erratum

In the original article by Li et al., entitled “SphK1/S1P Mediates PDGF-Induced Pulmonary Arterial Smooth Muscle Cell Proliferation via miR-21/BMPRII/Id1 Signaling Pathway” [Cell Physiol Biochem 2018;51(1):487-500, DOI: 10.1159/000495243], the original method section contained an error on page 489:

The source of the ELISA kit used for measuring S1P level (R&D Systems, Minneapolis, MN, USA) is incorrect. The kit was provided by (Shanghai Westang Bio-Tech CO., LTD, Shanghai, China).


The sentence should thus read as follows:

Enzyme-linked immunosorbent assay (ELISA)
The S1P levels in cell culture supernates and cell lysates were measured using a rat S1P Elisa kit (Shanghai Westang Bio-Tech CO., LTD, Shanghai, China) according to the manufacturer‘s instructions.


The authors sincerely apologize for this error.
