The dermal papilla comprises the specialised mesenchymal cells at the base of the hair follicle. Communication between dermal papilla cells and the overlying epithelium is essential for differentiation of the hair follicle lineages. We report that Sox2 is expressed in all dermal papillae at E16.5, but from E18.5 onwards expression is confined to a subset of dermal papillae. In postnatal skin, S...

The identification of lung tumor-initiating cells and associated markers may be useful for optimization of therapeutic approaches and for predictive and prognostic information in lung cancer patients. CD133, a surface glycoprotein linked to organ-specific stem cells, was described as a marker of cancer-initiating cells in different tumor types. Here, we report that a CD133+, epithelial-specific...

Microvascular lesion in diabetic peripheral arterial disease (PAD) still cannot be resolved by current surgical and interventional technique. Endothelial cells have the therapeutic potential to cure microvascular lesion. To evaluate the efficacy and immune-regulatory impact of intra-arterial infusion of autologous CD133(+) cells, we recruited 53 patients with diabetic PAD (27 of CD133(+) group ...

BACKGROUND Expression of human CD133 (human prominin-1) in cancer cells has been postulated to be a marker of stemness and is considered as a putative marker of cancer stem cells (CSCs). We designed a study to describe the expression pattern of CD133 in normal skin and in epithelial cutaneous neoplasms. METHODS The CD133 immunohistochemical expression of forty-three eccrine and apocrine tumor...

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...

Highly metastatic and chemotherapy-resistant properties of malignant melanomas stand as challenging barriers to successful treatment; yet, the mechanisms responsible for their aggressive characteristics are not fully defined. We show that a distinct population expressing CD133 (Prominin-1), which is highly enriched after administration of a chemotherapeutic drug, dacarbazine, has enhanced metas...

OBJECTIVE To investigate the correlation between CD133-positive gastric cancer and clinicopathological features and its impact on survival. METHODS A search in the Medline and Chinese CNKI (up to 1 Dec 2011) was performed using the following keywords gastric cancer, CD133, AC133, prominin-1 etc. Electronic searches were supplemented by hand searching reference lists, abstracts and proceedings...

Hepatocellular carcinoma (HCC) is an aggressive disease with a poor outcome due to the high incidence of metastasis. Cancer stem cells (CSCs) have been identified to be responsible for tumor progression and may be generated by epithelial-mesenchymal transition (EMT) characteristics. CD133 is a specific surface marker for liver cancer stem cells (LCSCs), which is also considered as an important ...

The prognostic/predictive role of both CD133 and Aldehyde dehydrogenase (ALDH) expression in human ovarian cancer remains elusive. This is an observational study that investigated the expression of CD133 and of ALDH enzymatic activity in fresh ovarian cancer samples and their association with different clinic-pathological patient' characteristics and explored their possible predictive/prognosti...
