Heart-shaped clones

Heart-shaped clones he intricate shape of the heart is formed by oriented cell growth patterns, according to Meilhac et al. on page 97. The heart is formed during embryo-genesis from a simple tube-like structure. As it grows, the tube morphs into the complicated but familiar shape of our four-chambered heart. How one set of cells in the tube expands to acquire the shape of a ventricle while oth...

Positive Selection on MMP3 Regulation Has Shaped Heart Disease Risk

BACKGROUND The evolutionary forces of mutation, natural selection, and genetic drift shape the pattern of phenotypic variation in nature, but the roles of these forces in defining the distributions of particular traits have been hard to disentangle. To better understand the mechanisms contributing to common variation in humans, we investigated the evolutionary history of a functional polymorphi...
