P-glycoprotein (P-gp) overexpression and tumor stem cells are thought to be important factors in the cross-resistance of cancer cells. There have been no studies on whether diallyl trisulfide (DATS) can reverse drug resistance in human osteosarcoma cells. In the present study, we demonstrated that DATS down-regulated P-gp expression and reversed drug resistance. DATS and methotrexate (MTX) decr...
Lymphatic malformations (LMs) are vascular anomalies thought to arise from dysregulated lymphangiogenesis. These lesions impose a significant burden of disease on affected individuals. LM pathobiology is poorly understood, hindering the development of effective treatments. In the present studies, immunostaining of LM tissues revealed that endothelial cells lining aberrant lymphatic vessels and ...
Objective: The application of human cord blood (hCB) is limited to children by using relatively small volume of cord blood that does not contain enough hematopoietic stem cells (HSCs). So, efforts for applying cord blood stem cells in transplantation have led to establishment of some approaches for ex vivo expansion of HSCs such as garcinol. Materials and Methods: CD133+ HSCs were separated by ...
BACKGROUND Acute kidney injury (AKI) in humans has few therapeutic options. In experimental models, administration of progenitor cells facilitates recovery from AKI. Human umbilical cord-derived CD133(+) progenitor cells promote endothelial repair in ischemic limb, heart and brain tissue. METHODS We examined the effects of human CD133(+) progenitor cells in bilateral ischemia-reperfusion (I/R...
CD133 has been shown to be an important stem cell factor that promotes glioma progression. However, the mechanism for CD133-mediated glioma progression has yet to be fully elucidated. In this study, we found that CD133 mRNA expression was a prognostic marker in three independent glioma patient cohorts, corroborating a putative role for CD133 in glioma progression. Importantly, we found that CD1...
BACKGROUND Recent findings suggest that cells with surface CD markers include cancer stem cells (CSCs) which can produce a cancer cluster, and that the presence of CSCs may be linked with prognosis. CD133 and CD44 are among the most useful markers for identification of colorectal CSCs. MATERIALS AND METHODS An immunohistological analysis of CD133 and CD44 was performed using tissue from cases...
The success of haematopoietic stem cell (HSC) transplantation largely depends on numbers of transplanted HSCs, which reside in the CD34(+) populations of bone marrow (BM), peripheral blood stem cells (PBSC) and umbilical cord blood (UCB). More specifically HSCs reside in the CD38(low/-) subpopulation, which cannot be objectively discriminated from mature CD34(+) CD38(+) progenitors. Thus, bett...
The CD133 glycoprotein is a controversial cancer stem cell marker in the field of neuro-oncology, based largely on the now considerable experimental evidence for the existence of both CD133+ve and CD133-ve populations as tumour-initiating cells. It is thought that decreasing oxygen tension enhances the complex regulation and phenotype of CD133 in glioma. In light of these ideologies, establishi...
We examined CD133 distribution in a human hepatoblastoma cell line (HuH-6 clone 5). We directly observed the cultured cells on a pressure-resistant thin film (silicon nitride thin film) in a buffer solution by using the newly developed atmospheric scanning electron microscope (ASEM), which features an open sample dish with a silicon nitride thin film window at its base, through which the scanni...
