Definition
| multipotent or pluripotent animal stem cells produced from differentiated cells in vitro by the addition of several genes that are expressed |
|
|
Term

|
|
Term
|
Definition

B) in empryonic development, a substance that causes a group of target cells to differentate in a particular way |
|
|
Term
|
Definition
| a diffusible substance whose concentration gradient determines a developmental pattern in animals and plants |
|

induced pluripotent stem cells
(iPS cells) |
|
Definition
| multipotent or pluripotent animal stem cells produced from differentiated cells in vitro by the addition of several genes that are expressed |
|
|
Term
|
Definition
| genes that determine the number and polarity of body segments |

Term
|
Definition
| conserved homeotic genes found in vertebrates, Drosophila, and other animal groups. Hox genes contain the homeobox domain and specify pattern and axis formation in these animals |
