Definition
| Cell that can differentiate into a variety of other cells but have a limited developmental potential in comparison to embryonic stem cells. I.e. Embryonic stem cells have the capacity to differentiate into more types of cells than adult stem cells. Adult stem cells are multipotent. |
|
|
Term
|
Definition
| A thin-walled hollow structure in early embryonic development that contains a cluster of cells called the inner cell mass from which the embryo arises. The outer layer of cells gives rise to the placenta and other supporting tissues needed for fetal development within the uterus while the inner cell mass cells gives rise to the tissues of the body. It is the embryo at 3-7 days and all the cells are pluripotent. |

Term
|
Definition
| Can develop into any kind of tissue |
|
|
Term
|
Definition
Cndifferentiated cells from which any type of cell
from that organism other than placental tissue can be created and they are extensively self-renewing. |
|
|
Term
|
Definition
| Describes cells that have the ability to differentiate into other cells but has lost its self renewal capacity, and has lost some developmental potential because they have become specialized. |
|
|
Term
|
Definition
| The pluripotent cells within the blastocyst that give rise to all tissues of the embryo |
|
|
Term
|
Definition
| Cells that give rise to blood cell types and cells related to blood |
|
|
Term
|
Definition
| Group of cells in the ovary surrounding the oocyte. The follicle grows along with the ovary until it releases the oocyte from the mature follicle. |
|
|
Term
|
Definition
| The process of oocyte development, whereby a primordial germ cell eventually becomes a mature ovum. |
|
|
Term
|
Definition
| A female ancestral germ cell that divides several times to give rise to an oocyte that, in turn, develops into an ovum (an egg). |
|
|
Term
|
Definition
| A female germ cell in the process of development. The oocyte is produced in the ovary by an ancestral cell called an oogonium and gives rise to the ovum (the egg) which can be fertilized. |

|
Term
|
Definition
| These tubules are located in the testicles, and are the specific location of meiosis of male reproductive cells, and the subsequent creation of gametes, namely spermatozoa. |
|
|
Term
|
Definition
| A cell type in the testes of male vertebrates that gives rise to primary spermatocytes by mitosis |
|
|
Term
|
Definition
| Initially, a spermatogonium divides by mitosis into two so-called primary spermatocytes. A primary spermatocyte is also diploid, and, in turn, gives place by meiosis to two secondary spermatocytes, which this time are haploid. |
|
|
Term
|
Definition
| the haploid male gamete that results from division of secondary spermatocytes. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte. |
|
|
Term
|
Definition
| The mature sperm which consists of a head body and tail and is haploid. |
