Retraction: Neural stem cell conditioned medium alleviates Aβ25-35 damage to SH-SY5Y cells through the PCMT1/MST1 pathway

On behalf of the coauthors and with much regret, I must retract our publication entitled “Neural stem cell conditioned medium alleviates Aβ_25-35 damage to SH-SY5Y cells through the PCMT1/MST1 pathway” published on European Journal of Histochemistry 2020;64(s2):3135 for the following reasons:

In Figure 1A, the data of 20 μM Aβ_25-35 for different time were confused with the data of 30 μM Aβ_25-35 for different time.
In Figure 2, the differential expression of PCMT1 is poor in repeatability. The authors need to revise the experimental design and steps to verify it again, re-do the experiment and conduct a more in-depth study.
