"First, and foremost, this finding helps us to understand the power that the modification of gene expression has on shaping our...

Sonic hedgehog, a gene that plays a crucial rule in the positioning and growth of limbs, fingers and toes, has been confirmed in an unexpected place in the embryos of developing mice "” the layer of cells that creates the skin. Named for a video game character, Sonic hedgehog describes both a gene and the protein it produces in the body. Its study is important to increase understanding of human birth defects. It was thought to be exclusively present in the cell layer that builds bone...

MADISON - Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) are wagging a finger at currently held notions about the way digits are formed. Studying the embryonic chick foot, the developmental biologists have come up with a model that explains how digits grow and why each digit is different from the others. As reported in the Proceedings of the National Academy of Sciences Online Early Edition the week of March 10-14, 2008, the scientists found that the...
