Sample Sentences & Example Usage
By trying to understand piebaldism, which doesn't have a particularly severe manifestation, so it's just a change in pigmentation, we can try to use the same techniques that we've developed to try and model and understand these other more serious diseases, which effectively are caused by similar mechanisms - cells not migrating properly in the early embryo.
Traditionally people thought that cells didn't make it to the front of embryos to pigment the belly because they just weren't migrating fast enough, what we've been able to show through our studies is that actually, if anything, cells in piebald animals migrate faster but they're just not proliferating enough. They're not making enough daughter cells to colonize - or cover - the whole region of the skin that needs to be covered by the time the pigmentation pattern is set down.
Piebaldism is actually a disease, it's caused by cells in the early embryo failing to migrate correctly.... failing to get to the right place. The cells which we're interested in, that cause piebaldism, are called melanocytes and they're responsible for pigmentation of hair and of the skin. These cells start at the back of the embryo and they try to migrate round through the skin and cover the whole of the( embryo's) skin. When they fail to do that properly you tend to get regions of skin or hair which are lacking in pigment, often regions at the front of an animal. This is common in cats...... tuxedo cats, and it's also common in horses and pigs and even in humans.
