In vitro culture of human ovarian tissue the following cryopreservation is proposed for follicular development. There are no techniques that guarantee successful maturation of the follicles within the excised tissue. The viability of cultured human ovarian tissue improved by adding some growth factors to the culture media. The efficiency of vitrification as the cryopreservation method for human...

Background & Aim: Clematis is an ornamental and medicinal plant that is primarily planted as an ornamental plant. Clematis orientalis is native to Asia and Central Europe, used as an antiseptic and refrigerant. The propagation of Clematis is very important. In this study, the effects of plant growth regulators on rooting and growth of the plants in vitro cult...

   Background: In this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. Methods: The developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of ...

borrelia microtti and borrelia persica are two iranian strains of spirochetes whose vectors are ornithodorous tholozani and ornithodorous erraticus which are responsible for relapsing fever. bsk medium has been used for in vitro culture of other strains of borrelia, although the two mentioned strains could not be successfully cultured in it. we have modified bsk medium by using guinea pig and f...

Plantlets under in vitro conditions transferred to ex vivo conditions are exposed to biotic and abiotic stresses. Furthermore, in vitro regenerated plants are typically frail and sometimes difficult to handle subsequently increasing their risk to damage and disease; hence acclimatization of these plantlets is the most important step in tissue culture techniques. An experiment was conducted unde...

Background: In the last few years, a marked decrease in male fertility has been reported. Environmental factors were recently suspected for this problem. The misuse of medicines especially antibiotics are among environmental factors that can affect reproductive system. Ciprofloxacin is a synthetic antibacterial agent belonging to the family of fluoroquinolones with a very broad spectrum effect ...

Background: Currently, ARTs are of indispensable importance in treatment of human infertility. While ARTs are considered to be safe, some studies suggest that ARTs manipulations may perturb the epigenetic information and subsequently the health of the offspring. To examine these events further, this study was conducted to assess the effect of superovulation, in vitro culture and vitrification o...

Prevention of malignant disease such as cancer is obviously much more important than therapy, so primary prevention tactics should be invoked with the greatest possible effort. Because delaying a disease such as cancer is somehow equivalent to cure and it is now generally accepted that cancer can be managed through chemopreventive interventions. Since a considerable number of known cancer chemo...

introduction: dental pulp-derived mesenchymal stem cells (mscs) have emerged as a promising tool for use in regenerative medicine. the in vitro growth kinetic and culture requirement of the cells derived from human dental pulp, which is the subject of this present study, is poorly described. materials and methods: stem cells were derived from human third molar and then characterized. the in vit...
