Depletion of podocytes, common to glomerular diseases in general, plays a role in the pathogenesis of glomerulosclerosis. Whether podocyte injury in adulthood can be repaired has not been established. Here, we demonstrate that in the adult human kidney, CD133+CD24+ cells consist of a hierarchical population of progenitors that are arranged in a precise sequence within Bowman's capsule and exhib...

The stem cell marker CD133/prominin-1, is a pentaspan membrane glycoprotein, which has also been identified as a cancer stem cell (CSC) marker in several solid tumor types, including those of the prostate, liver, colon and brain. The function of CD133 in these tumors is still unknown. We hypothesize that the function of CD133 is correlated with the characteristics of the CD133+ CSCs and may aff...

CD133 is considered as a stem-like cell marker in some cancers including gastric cancers, and Notch1 signaling is known to play an important role in the maintenance and differentiation of stem-like cells. We aimed to investigate whether Notch1 signaling contributes to the carcinogenesis of gastric cancers and CD133 induction. CD133 expression was detected in 51.4% of diffuse type gastric cancer...

BACKGROUND CD133 has been used to identify normal and cancer stem cells from several different tissues. Nowadays some researchers have reported that CD133 expression was not restricted to cancer stem cells (CSCs) of colorectal cancer and brain tumors, and CD133-negative subsets could also initiate tumors. We therefore performed a meta-analysis to assess the value of CD133 as a biomarker of CSCs...

Platinum-based chemotherapy is the first-line treatment for non-small cell lung cancer, but recurrence occurs in most patients. Recent evidence suggests that CD133(+) cells are the cause of drug resistance and tumor recurrence. However, the correlation between chemotherapy and regulation of CD133(+) cells has not been investigated methodically. In this study, we revealed that CD133(+) lung canc...

CD133/Prominin-1 is a pentaspan transmembrane protein that has been frequently used as a biomarker for cancer stem cells, although its biological function is unclear. The aim of our study was to explore the intrinsic functions of CD133 membrane protein in hepatoma cells during autophagy, apoptosis, tumorigenesis and cell survival through expression or downregulation of CD133. In this study, CD1...

BACKGROUND An increasing number of evidence suggests that pancreatic cancer contains cancer stem cells (CSCs), which may be relevant to the resistance of chemotherapy. Latexin (Lxn) is a negative regulator of stem cell proliferation and we investigate the effects of Lxn on CD133+ pancreatic cancer stem-like cells. METHODS CD133+ miapaca-2 cells, a human pancreatic carcinoma cell line, were is...

OBJECTIVE Several studies have shown that human gliomas contain a small population of cells with stem cell-like features. It has been proposed that these "cancer stem cells" may be uniquely responsible for glioma formation and recurrence. However, human gliomas also contain an abundance of cells that closely resemble more differentiated glial progenitors. Animal model studies have shown that th...

Anaplastic thyroid cancer (ATC) is a lethal solid tumor with poor prognosis because of its invasiveness and its resistance to current therapies. Recently, ATC-CD133+ cells were found to have cancer stem cell (CSC) properties and were suggested to be important contributors to tumorigenicity and cancer metastasis. However, the molecular pathways and therapeutic targets in thyroid cancer-related C...
