Correction to: Scientific Reports https://doi.org/10.1038/s41598-018-38086-1, published online 18 February 2019

The original version of this Article contained extensive errors in the Reference list. References 13–23 were incorrectly listed as references 14–24 respectively, and reference 24 was incorrectly listed as reference 13.

In addition, reference 26 was omitted and is listed below:

Page L.K. et al. The immune thrombocytopenic purpura (ITP) bleeding score: assessment of bleeding in patients with ITP. Br J Haematol, 138, 245–8 (2007).

Finally, the original version of this Article contained errors in the in-text citations.

In the legend for Table 1,

“*Median and range are shown. **Bleeding score was evaluated according to the ITP Bleeding Scale (IBLS) proposed by Page and col. comprising 3 grades: from 0 (none) to 2 (marked bleeding) assessed at nine anatomical sites by history over the previous week25.”

now reads:

“*Median and range are shown. **Bleeding score was evaluated according to the ITP Bleeding Scale (IBLS) proposed by Page and col. comprising 3 grades: from 0 (none) to 2 (marked bleeding) assessed at nine anatomical sites by history over the previous week26.”

In the Materials and Methods, under the subheading ‘Cell culture’,

“CD34-positive cells were obtained from umbilical cord blood or from product of leukapheresis by immunomagnetic separation (Miltenyi Biotech Ltd., Bisley, Surrey, UK) as described previously24.”

now reads:

“CD34-positive cells were obtained from umbilical cord blood or from product of leukapheresis by immunomagnetic separation (Miltenyi Biotech Ltd., Bisley, Surrey, UK) as described previously25.”

These errors have now been corrected in the HTML and PDF versions of the Article.
