how does hair “get in there?” or was it…a developing baby? this was an incredibly interesting video…i can’t seem to get enough of this stuff. i’m in the beginnings of getting a nursing degree with high hopes of becoming a certified nurse midwife. and i love reading any/all blogs…and i just popped across yours today and i’ve been immersed in it for the last hour!! thanks for posting such well-written, easy-to-understand stuff!! but seriously, how did the hair, skin, tooth, etc. form?
Dermoids are tumors that arise from germ cells – the cells that might have gone on to become the the female eggs. These cells are pluripotent, meaning that have not yet differentiated enough to be dedicated to becoming any particular kind of tissue. Instead, they still have the potential to become any kind of tissue. Dermoids classically differentiate into fat, hair, skin, and bone structures – most commonly tooth and jaw structures. A common misconception is that a dermoid was at some point a fetus or a baby, which it was not. The derive de-novo from germ cells, without fertilization of any kind.
Thank you for your explanation. It was perfect. Not from a medical perspective, but from my perspective.
Hello, Neat post. There’s a problem with your website in internet explorer, might test this? IE still is the marketplace chief and a huge component to people will miss your excellent writing because of this problem.
