 ES/MEF cell dataset published by Islam et al

Hello, and sorry for asking this here,

i saw that in you paper you used  ES/MEF cell dataset published by Islam et al. I want to use this dataset to benchmark some single cell DE tools but i can not find ground truth for 1000 TOP DE genes i see being used in papers. Can you provide me some instructions on how to find/get this data?

Thanks in advance,
Dalibor
