the effect of in planta tiba and proline on in vitro seedlings and cell culture of sugar beet was investigated. sterilized seeds were grown in vitro on ½ strength ms medium supplemented with 0 or 3 mg/l tiba. calli obtained on young leaves cultured on ms medium containing 1 mg/l bap, were used for the intiation of cell suspension cultures using ms basal composition supplemented with 0 or 50 m m...

Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyll...

Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...

OBJECTIVES Endometriosis is a complex gynecologic disease with unknown etiology. Noscapine has been introduced as a cancer cell suppressor. Endometriosis was considered as a cancer like disorder, The aim of present study was to investigate noscapine apoptotic effect on human endometriotic epithelial and stromal cells in vitro. MATERIALS AND METHODS In this in vitro study, endometrial biopsies...

BACKGROUND During the development and progression of endometriotic lesions, excess fibrosis may lead to scarring, chronic pain, and altered tissue function. However, the cellular and molecular mechanisms of fibrosis in endometriosis remain to be clarified. OBJECTIVES The objective of the present study was to investigate whether the Wnt/β-catenin signaling pathway was involved in regulating th...

background: letrozole is an aromatase inhibitor which can decrease estrogen production in peripheral tissues and endometriosis. danazol, as an androgen, inhibits estrogen production in ovaries and recently has been introduced as an aromatase inhibitor. this study was designed to compare the effects of danazol with letrozole on endometriosis symptom relief. materials and methods: this study was ...

introduction: the spermatogonial stem cells (sscs) form the basis of spermatogenesis. in vitro culture of germ cells is useful for the purification and increasing of sscs for transplantation. in the present study, we examined: in vitro the effects of co-culture with sertoli cells, gdnf, scf and gm-csf on efficiency of spermatogonial cells colony formation and spermatogenesis induction in the re...

Background This study was undertaken to investigate the efficiency of two different embryo somatic cell co-culture conditions tissue culture medium 199 (TCM199)–vero cells and Menezo B2 (B2)-vero cells for the in vitro developmental quantity and quality of bovine embryos. MaterialsAndMethods Bovine oocytes were allowed to mature and subsequently undergo fertilization in vitro. Their presumptive...
