Evolution of Barrett’s esophagus through space and time at single-crypt and whole-biopsy levels

Clonal dynamics of Barrett’s esophagus (BE) leading to cancer are poorly understood. Here, they report BE segments are clonal, have frequent mutations at the gastro-esophageal junction, genomic instability precedes genome doubling/clonal expansion, and a correlation between inter- and intra-biopsy g...

Sumario:Clonal dynamics of Barrett’s esophagus (BE) leading to cancer are poorly understood. Here, they report BE segments are clonal, have frequent mutations at the gastro-esophageal junction, genomic instability precedes genome doubling/clonal expansion, and a correlation between inter- and intra-biopsy genetic diversity.
