(Wednesday, December 15, HealthDay News) - American scientists have pinpointed 2,000 genetic regions which play a crucial role in human development at the beginning.
Regions, called enhancers, activate the expression of genes, as embryonic stem cells begin to divide to form tissues of embryo in more and more, explains the main study, Joanna Wysocka, biology of development and chemical biology and systems at the school of medicine, Stanford University assistant professor author.
"It is clear that these amplifiers are becoming active at specific times during development," Wysocka said in a University Press release. "Now we have more than 2,000 items that can be used to study the development and isolate the transitional cell populations."
The study was published online 15 December in nature.
"This will be a tremendous resource for researchers who are interested in locating cells involved in human development at the beginning," said Wysocka. "It will be very interesting to learn how these amplifiers affect gene expression in each cell type.
