The potentials of umbilical cord-derived mesenchymal stem cells in the treatment of multiple sclerosis.

Stem cell therapy has indicated a promising treatment capacity for tissue regeneration. Multiple sclerosis is an autoimmune-based chronic disease, in which the myelin sheath of the central nervous system is destructed. Scientists have not discovered any cure for multiple sclerosis, and most of the treatments are rather palliative.

DJ1 and microRNA-214 act synergistically to rescue myoblast cells after ischemia/reperfusion injury.

Ischemia/reperfusion injury is a tissue injury occurring post-reperfusion of tissues with pre-existing ischemia. A good blood supply to tissues aids in the survival of ischemic tissue, however, due to prolonged ischemia the levels of ATP decrease and pH declines leading to acidosis. Reduced ATP leads to an increase in the AMP/ATP ratio, causing cessation of intracellular calcium transport, hence calcium overload and cell death.

Distinct effect of fetal bovine serum versus follicular fluid on multipotentiality of human granulosa cells in in vitro condition.

This study aimed to develop an appropriate medium for preservation of multipotentiality in human granulosa cells. To compare the possible effect of different media supplemented with follicular fluid or fetal bovine serum, granulosa cells were cultured in vitro over a period of 14 days. Stemness feature and any alteration in the cell phenotype were monitored using colony count assay and flow cytometry analysis by monitoring the expression of Oct3/4 and GATA-4 factors.

Advantages of Sheep Infrapatellar Fat Pad Adipose Tissue Derived Stem Cells in Tissue Engineering.

Purpose: The goal of this study has been to evaluate adipose tissue derived stem cells (ADSCs) from infrapatellar fat pad and characterize their cell surface markers using anti-human antibodies, as adipose tissue derived stem cells (ADSCs) have great potential for cellular therapies to restore injured tissues.

Methods: Adipose tissue was obtained from infrapatellar fat pad of sheep. Surface markers evaluated by flow cytometry.

Texosome-anchored superantigen triggers apoptosis in original ovarian cancer cells.

Texosomes, nano-endosomal vesicles, are candidates for cancer immunotherapy due to their immunostimulating properties. We designed a new structure based on texosome and staphylococcal enterotoxin B (SEB) and assessed its cytotoxic impact on an ovarian cell line. Texosomes were isolated from tumor cells, and SEB was anchored onto by protein transfer method.

The effect of BSO-induced oxidative stress on histologic feature of testis: testosterone secretion and semen parameters in mice.

Objectives: Buthionine sulfoximine (BSO) inhibits synthesis of glutathione as the main intracellular antioxidant. The aim of the present study is to investigate the effect of BSO-induced oxidative stress on histological structure of testis, testosterone secretion and semen parameters.

Materials And Methods: Thirty male BALB/c mice were divided into 3 groups.

Exosome/staphylococcal enterotoxin B, an anti tumor compound against pancreatic cancer.

Purpose: Exosomes (EXOs) are acellular vehicles used for cancer immunotherapy due to their immune-inducing properties. We synthesized a novel structure based on EXOs and staphylococcal enterotoxin B (SEB) and surveyed its cytostatic effect on a pancreatic cell line.

Methods: EXOs were purified from tumor cells and SEB was anchored on it by protein transfer method.

Ultrastructural and morphometrical study of preimplantation endometrium in superovulated mice treated with progesterone or Sildenafil.

Background: Endometrial development has an important role in blastocyst adhesion and implantation. During IVF cycles, endometrial development is enhanced by progesterone.

Objective: The aim of this study was to compare ultrastructural and morphometrical characteristics of mice uterine endometrium in natural cycle with those in superovulated cycles received progesterone or Sildenafil.

Staphylococcal entorotoxin B anchored exosome induces apoptosis in negative esterogen receptor breast cancer cells.

Exosomes (EXO) are acellular vehicles used for cancer immunotherapy due to their immune inducing properties. To identify whether designed structure based on tumoral EXO have a cytotoxic effect together with a potent immunological property, we synthesized a novel structure based on EXO and staphylococcal entrotoxin B (SEB), two immune inducer substances, and surveyed its cytostatic effect on the breast cancer cell line. EXO were purified from tumor cells and SEB was anchored on it by protein transfer method.

Effect of polyunsaturated fatty acids on secretory phospholipase A2 type IIa in ectopic endometrial cells.

Background: Endometriosis is a common chronic inflammation which leads to infertility and chronic pelvic pain in affected women. Secretory phospholipase A2 type IIa (sPLA2IIa) is an acute phase reactant that is markedly increased in inflammatory disorders.

Objective: To assess the effects of ω-3 and ω-6 polyunsaturated fatty acids (PUFAs) administration in endometrial cells culture on sPLA2IIa level and cell survival comparing homolog ectopic versus eutopic endometrial cells from endometriosis patients.

Degenerative effect of Cisplatin on testicular germinal epithelium.

Purpose: The present study was designed to explore the effect of intraperitoneal administration of cisplatin in germinal epithelium of mice. There are few reports on the side effect of cisplatin on spermatogenesis when are used as anticancer drug. Therefore, in the present study the effect of cisplatin on spermatogenesis was evaluated by electron microscopy.
