Timing of initial meiotic stages

Size of the gametes produced by meiosis

Age at which functional gametes are first produced

Number of gametes produced from one precursor cell

Aggregate at discontinuities in vessel walls

Form a homogeneous plug of platelets

Remove fibrin to promote clot formation

Release granule contents to assist plug formation

Transfer of the nucleus of a differentiated cell into an enucleated somatic cell

Transfer of mature germ cells into cell culture

Removal of cells of the epiblast from a blastocyst

Expression of key transcription factors in a somatic cell

Extravillous trophoblasts

Foetal capillary endothelium

Cytotrophoblasts

Syncytiotrophoblasts

Septum of the heart

Long bones of the limbs

Structure of the testis

Epithelium of the bowel

Some sensory neurons will differentiate into other neuronal types such as motor neurons

The axons of the sensory neurons will continue to grow into other regions of the embryo

The number of sensory neurons in the spinal cord will be the same as normal

More sensory neurons will undergo apoptosis than normal

In a concentration gradient generating Leydig cells 

Only on adjacent cells due to it being attached to the producing cell

Through the bloodstream to a number of tissues

Locally within the testis in a paracrine manner

Express the SRY gene

Undergo ovulation to reach full functional maturity

Reside in seminiferous cords/tubules within gonads

Enter meiosis soon after colonising the gonad
