Of Stem Cells and Germ Cells [PDF]

Reproduction in Domestic Animals, 2011
ContentsStem cells have an intrinsic capacity to self‐renew and can differentiate to at least one specialized cell type. Different types of stem cells exist that can be culturedin vitro. The identity of the stem cells is marked by their origin and differentiation potential.

Prospects for transgenesis in the chick [PDF]

, 2004
Research to develop a useful method for genetic modification of the chick has been on-going since the first demonstrations in the mouse in the 1980s that genetic modification is an invaluable tool for the study of gene function. Manipulation of the chick

Defending the genome from the enemy within:mechanisms of retrotransposon suppression in the mouse germline [PDF]

, 2013
The viability of any species requires that the genome is kept stable as it is transmitted from generation to generation by the germ cells. One of the challenges to transgenerational genome stability is the potential mutagenic activity of transposable ...

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.
