Did you know that your body is made up of
millions and millions and millions of cells. Hi I’m Janice Creneti and I’m here to talk
to you about what is a somatic cell. Somatic actually comes from the Greek word which means
body. And it’s the type of cell that makes up most of you. Your hair cells, your finger
nails, your skin, your organs your bones, all those are made of cells, somatic cells.
Somatic cells have forty six chromosomes that’s the number that’s normal in a healthy somatic
cell. Somatic cells are important because as we’ve started to investigate something
called cloning, it’s actually important to understand the difference between a somatic
cell and what we would call a gammie or a sex cell. Those are your sperm cells and your
egg cells, sperm and egg come together to create a fertilized embryo that eventually
develops into a human, a cat, a dog. But the somatic cells are the actual body cells once
they differentiate, which means they now have a specific job to do. They’re a hair cell,
they’re an eye cell, they’re a skin cell. Well somatic cells can actually be implanted
with a complete fertilized nucleus in order to clone things like sheep and even now a
dog. So somatic cells are what we would think of as being the typical cell in your body.
I’m Janice Creneti and this is what is a somatic cell.
