Although flow cytometry is useful for studying neural lineage relationships, the method of dissociation can potentially bias cell analysis. We compared dissociation methods on viability and antigen recognition of mouse central nervous system (CNS) tissue and human CNS tumor tissue. Although nonenzymatic dissociation yielded poor viability, papain, purified trypsin replacement (TrypLE), and two ...

Background and aim: Glioblastoma (GBM) is one of the most common and aggressive brain tumors with a median survival of 12-14 months. The aim of present study was to evaluate the gene expression profile of stem cell markers Nanog and CD24 in GBM and to determine its relationship to outcome in terms of treatment response and overall survival. Material and methods: This was a retrospective as well...

AIMS CD44, CD24 and ALDH1 are the most consistently used biomarkers to identify and characterise the breast cancer stem cell (CSC) phenotype. However, most studies performed until now analysed samples of invasive ductal carcinomas of no special type (IDC-NST). Therefore, prevalence and clinical significance of these CSC markers in breast carcinomas of special histological types (SHT) is largely...

We studied the correlation between epidermal growth factor receptor (EGFR) and the tumor stem cell markers CD44/CD24 in breast invasive ductal carcinoma (BIDC) and their relationship with prognosis. We analyzed the clinical data of 139 BIDC cases retrospectively, detecting EGFR, CD44, and CD24 expressions in tumor tissue using immunohistochemistry. The proportion of EGFR-, CD44-, and CD24-posit...

Multiple sclerosis (MS) is a chronic neurological disease of unknown etiology, but a genetic basis for the disease is undisputed. We have reported that CD24 is required for the pathogenicity of autoreactive T cells in experimental autoimmune encephalomyelitis, the mouse model of MS. Here we investigate the contribution of CD24 to MS by studying single-nucleotide polymorphism in the ORF among 24...

Cancer stem cells are speculated to have the capability of self-renewal and re-establishment of tumor heterogeneity, possibly involved in the potential relapse of cancer. CD44+CD24-/lowESA+ cells have been reported to possess tumorigenic properties, and these biomarkers are thought to be highly expressed in breast cancer stem cells. Cell behavior can be influenced by biomolecular and topographi...

BACKGROUND Cells within breast cancer stem cell populations have been confirmed to have a CD44(+)CD24(-) phenotype. Strong expression of CD44 plays a critical role in numerous types of human cancers. CD44 is involved in cell differentiation, adhesion, and metastasis of cancer cells. METHODS In this study, we reduced CD44 expression in CD44(+)CD24(-) breast cancer stem cells and investigated t...

Identification of Cancer stem cell lineage subpopulations of tumor cells within the tumor mass offer to identify targets for therapeutic interventions and a better understanding of carcinogenesis. The main objective of this study was to evaluate the prognostic value of cancer stem cell lineage markers i.e., CD44, CD24 and Epithelial specific antigen (ESA) in canine mammary tumours using triple ...

PURPOSE Evidence is lacking whether the number of breast tumor-initiating cells (BT-ICs) directly correlates with the sensitivity of breast tumors to chemotherapy. Here, we evaluated the association between proportion of BT-ICs and chemoresistance of the tumors. METHODS Immunohistochemical staining(IHC) was used to examine the expression of aldehyde dehydrogenase 1 (ALDH1) and proliferating c...

Psoriasin (S100A7), a member of the S100 family of calcium-binding proteins, is highly expressed in high-grade ductal carcinoma in situ (DCIS) and in the benign hyperproliferative skin disorder psoriasis. The gene that encodes psoriasin and many other S100 genes are located within a gene cluster on chromosome region 1q21, known as the epidermal differentiation complex. This cluster contains gen...
