Modulation of steroidogenesis in human ovarian granulosa cells during aging.

P-17: Modulation of Wnt/?catenin and AktSignaling Activities in Rat Granulosa Cells byUsing Recombinant Secreted Frizzled RelatedProtein Type-4

P-58: Secreted Frizzeled Related Protein Type-4as an Inducer of Apoptosis and Terminal Differentiationof Rat Granulosa Cells

Background: Involvement of Wnt proteins and one of its antagonist known as secreted Frizzled Related Protein type-4 (sFPRP-4) was reported in rodent ovarian follicular development. Other studies showed an ap- Abstracts of the 11th Royan International Congress on Reproductive Biomedicine 7 7 International Journal of Fertility & Sterility (IJFS), Vol 4, Suppl 1, Summer 2010 optotic-associated exp...

The effect of exosomes derived from human ovarian epithelial cancer cells on the secretion of AMH and Inhibin in granulosa cells

Exosomes are secreted by different types of cells and known as biological packages. Exosomes have significant role in intercellular communications and involved in the development and progression of various diseases such as cancer. Inhibin B and anti-mullerian hormone (AMH) are markers of granulosa cell tumors (GCT) and due to the role of exosomes in the progression of cancer, in this experiment...

DIFFERENTIATION OF HUMAN OVARIAN FOLLICULAR GRANULOSA CELLS INTO KERATINOCYTES

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...

I-24: Individualized Controlled Ovarian Stimulation (iCOS)

Background: With the recent development of recombinant gonadotropins (FSH and LH), it has become possible to further adjust the stimulation protocol according to the expected needs of the patient. In this respect, the possible beneficial role of exogenous LH activity supplementation for stimulated ART cycles has received increasing attention. According to the two-cell, two- gonadotropin theory,...
