Correction to: Signal Transduction and Targeted Therapy https://doi.org/10.1038/s41392-021-00627-y, published online 18 June 2021
In the process of collating the raw data, the authors noticed three images in Fig. 4 were used incorrectly. They made an inadvertent mistake by arranging the figure of M2 Group into M2+LY294002 Group in Fig. 4k during the revision process.

The correct Fig. 4 is provided as follows:

Fig. 4 BM-M1 and BM-M2 exerted opposing effects on megakaryopoiesis and platelet production in vitro. (f) Representative western blots of p-AKT, AKT and GAPDH in BM-M0, BM-M1 and BM-M2. (k) Representative CFU-MK images (scale bars represent 50 μm) were analyzed after 12 days of coculture.
In addition, the bands of Akt and GAPDH in Fig. 5b were vertically flipped and inserted as p-Akt and GAPDH in Fig. 4f by mistake.
The correction did not affect any of the results or discussion as present in the original publication. The authors apologize for this inadvertent mistake.
The original article has been corrected.
