Building a virus-free COVID-19 disease model based on differential ACE2 expression in human cell lines. (a) 1305 cell lines from the Cancer Cell Line Encyclopedia (CCLE) project were sorted on the base of their ACE2 TPM (Transcripts Per Million) content. Cell lines displaying a ACE2 TPM value equal to 0 (Low ACE2) or greater than 1 (High ACE2) were grouped. (b) Top 50 differentially expressed transcripts between Low ACE2 vs. High ACE2 cell lines.
