the brain and spinal cord have a limited capacity for self-repair under damaged conditions. one of the best options to overcome these limitations involves the use of phytochemicals as potential therapeutic agents. in this study, we have aimed to investigate the effects of di-(2-ethylhexyl) phthalate (dehp) on hippocampus-derived neural stem cells (nscs) proliferation to search phytochemical can...
Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine. The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...
introduction: accumulating evidences indicated that during increasing of the animals' age, the number and the functional properties of hematopoietic stem cells (hscs) become altered because of a gradual decrease in replication potential. the efficient factors in this process are dna damaging, reduced telomerase activity, shortening of telomeres and oxidative stresses. for overcoming these fact...
objective: cryopreservation of immature testicular tissue should be considered as an important factor for fertility preservation in young boys with cancer. the objective of this study is to investigate whether immature testicular tissue of mice can be successfully cryopreserved using a simple vitrification procedure to maintain testicular cell viability, proliferation, and differentiation capac...
Introduction: Now days, several studies have indicated the central nervous system has capacity for endogenous repair. But, the proliferation of endogenous neural stem cells (NSCs) is insufficient for treatment of neurodegenerative diseases. So, it sound that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The Acca sellowiana (Feijoa) extract as herbal extract is ...

Skeletal muscle satellite cells are heavily involved in the regeneration of skeletal muscle in response to the aging-related deterioration of the skeletal muscle mass, strength, and regenerative capacity, termed as sarcopenia. This study focused on the effect of tocotrienol rich fraction (TRF) on regenerative capacity of myoblasts in stress-induced premature senescence (SIPS). The myoblasts was...
rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. the purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (mscs). five new zealand white male rabbits were used in the present study. a 2-mm hole was created in the a...
fully mature dendritic cells (dcs) play pivotal role in inducing immune responses and converting naïve t lymphocytes into functional th1 cells. we aimed to evaluate listeria monocytogenes-derived protein fractions to induce dc maturation and stimulating t helper (th)1 immune responses. in the present study, we fractionated listeria monocytogenes-derived proteins by adding of ammonium sulfate in...
Abnormal smooth muscle cell proliferation is a hallmark of vascular disease. Although growth factors are known to contribute to cell hyperplasia, the changes in metabolism associated with this response, particularly mitochondrial respiration, remain unclear. Given the increased energy requirements for proliferation, we hypothesized that PDGF (platelet-derived growth factor) would stimulate glyc...
