Like tuning in to an elusive radio frequency in a busy city, human embryonic stem cells must sort through a seemingly endless number of options to settle on the specific genetic message, or station, that instructs them to become more-specialized cells in the body. Now researchers have shown that this tuning process is accomplished in part by restricting the number of messages, called transcripts, produced from each gene.
