Specimen Details

Sample GEO ID:	GSM108560
Sample Description:	gd 12 whole testes
Sample Name:	Gaido_Testes_gd12_14_14Dec2005
Component(s) Sampled:	testis (EMAPS:1797220) ;
Organism:	Mus musculus
Tissue:	testis
Strain:	CD-1
Genotype:	wild type
Sex:	male
Development Age:	12 dpc
Stage:	TS20
Pooled Sample:	Yes
Pool Size:	5
Dissection Method:	Whole organ excision
Experiment Design:	CD-1 mice are time-mated within a 2 hour window. Pregnant CD-1 mice are euthanized by standard carbon dioxide asphyxiation. All fetuses are killed by decapitation with a scalpel. Fetal gonads are removed from fetuses at gestation days 11, 12, 14, 16, 18, and postnatal day 2, snap frozen in liquid nitrogen and stored at -80ºC.

Title:	Gene expression profiling of whole testes in embryonic (gestational day 11, 12, 14, 16 & 18) and postnatal day 2 mice. (GUDMAP Series ID: 3)
Summary:	The overall objective of this proposal is to map the temporal and spatial dynamics of gene expression in the fetal mouse testis at key developmental timepoints. Urogenital tract malformations are the most common birth defects in males and their incidence together with other male reproductive health concerns such as reduced fertility and testicular cancer are reportedly on the rise in the human population. To better understand the impact of genetic factors and environmental influences on testicular development, it is important to first understand normal gene expression patterns and signaling cascades within the fetal testis during development. The goal of this study is to identify cell-specific genes that can be used as biomarkers for key differentiation events.
Type:	developmental time course
Overall Design:	Day to day comparison in whole testes throughout development with triplicates at each time point. Each sample is a pair of testes from a single animal and each animal is taken from a different dam.
