When was the first complete map of human gene expression published?
Quick Answer
The first large-scale maps of human gene expression appeared in the early 2000s, especially around 2002 and 2003. They showed which genes are active in different tissues.
The Full Story
Around 2002 and 2003, researchers began publishing large-scale human gene-expression maps based on emerging genomic technologies. These maps showed how different genes are turned on or off in tissues such as the brain, liver, and blood. They helped researchers understand normal biology and disease mechanisms. This work laid the groundwork for modern transcriptomics and systems biology.
