Background: Metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. The aim of this study was to determine the relationship between the expression of stem cell marker CD166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.Methods: From 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in Babol...

conclusions large amounts of preclinical studies have been made of stem cells and there is an increasing interest to perform these studies within the human population but preclinical studies are insufficient; therefore, much more and efficient studies should be conducted to evaluate the efficacy and safety of stem cells. context musculoskeletal injuries may be painful, troublesome, life limitin...

Background The present study was designed to evaluate the survival and proliferation of spermatogonial stem cells from cryptorchid mouse testis in co-culture system over a 3 weeks period. MaterialsAndMethods Sertoli and spermatogonial cells were isolated from bilateral cryptorchid mouse model testes. Isolated spermatogonial cells were co-cultured with Sertoli cells in minimal essential medium (...

Survival of patients with multiple myeloma has improved substantially because of availability of new therapies including autotransplants, immunomodulating drugs and proteasome-inhibitors. Second primary cancers have emerged as an important determinant of morbidity and mortality among cancer survivors. Even though there is an increased risk of new cancers of the lymphoreticular and haematopoetic...

The stem anatomy and pollen morphology of Iranian members of the genus Corydalis (except C. seisumsiana in pollen morphology) were studied using light and SEM microscopy. The results verified the argument that the tuberous sections of Corydalis, including Radix-cava, Corydalisand Leonticoides could be classified in a single subgenus as a natural grouping. The study also revealed that the specie...

thepetroleum concentrations are contaminant important sources in the environment. hydrocarbon’s contaminants depend on their type and concentration can cause variable toxicity in soils, on the other hand, different kinds of plants also response concentration of contaminant differently, because of the diversity of physiological and morphological characteristics. in this study the effect of diffe...

The definition of stem cell is “an unspecialized cell that gives rise to a specific specialized cell, such as a blood cell”. Stem Cell is the original of life. All cells come from stem cells. Serving as a repair system for the living body, the stem cells can divide without limit to replenish other cells as long as the living body is still alive. When a stem cell divides, each new cell has the p...

Background: The chick embryo is a classical model to study embryonic development. However, most researchers have not studied the effect of embryonic manipulation on chick hatchability. To determine the effect of egg orientation and type of sealing film on the hatchability of cultured embryos, and to determine the fate of adulte stem cells injected into the blastoderm. Materials and Methods: Win...

Glaucoma is the leading cause of preventable blindness worldwide. Despite tremendous advances in medical and surgical management of glaucoma in the recent years, the prevalence of glaucoma related blindness is anticipated to increase in the future decades because of the aging population. Stem cells have the potential to change the glaucoma management in several ways. There are several areas of ...
