• The t-sne figure in original paper can be reproduced from the t-sne result matrix pre-stored by author on https://www.dropbox.com/sh/dn4gwdww8pmfebf/AACXYu8rda5LoLwuCZ8aZXfma?dl=0.

• The instruction can be found on the project github: https://github.com/cssmillie/ulcerative_colitis

• The figure is exactly same as figure C in p.715 for Stromal (Fib) in https://www.cell.com/cell/pdf/S0092-8674(19)30732-9.pdf

Then we reproduce the t-sne from the pre-stored data and code showed in this repository in “new_comparison.R”
