Cancer/Testis antigens (CTAs) as a group of tumor antigens are the novel subjects for developing cancer vaccine and immunotherapy approaches. They aberrantly express in tumors with highest normal expression in testis, and limited or no expression in normal tissues. There are important similarities between the processes of germ-cell and cancer cell development Spermatogenesis begins at puberty w...

Background: Spermatogenesis is a complex and highly organized process of proliferation and differentiation of spermatogonial stem cells. Spermatogonial stem cells (SSCs) as a unique stem cell have the potential to self-renewal, differentiation and transmit genetic information to the next generation and play a vital role in maintaining fertility. Sertoli cells as the only somatic cells within th...

Background & Aims: Stem cells are undifferentiated cells and are found in different tissues. These cells have capacity of self-renewal and differentiation into other lineages. Granulosa cells (GCs) are the multipotent stem cells. In the present research we evaluated the differentiation potential of GCs into keratinocytes. Material & Methods: GCs were cultured after enzymatic isolation from ova...
