CD133 (Prominin) Negative Human Neural Stem Cells Are Clonogenic and Tripotent

CD133 (Prominin) is widely used as a marker for the identification and isolation of neural precursor cells from normal brain or tumor tissue. However, the assumption that CD133 is expressed constitutively in neural precursor cells has not been examined.

Methodology/Principal Findings

In this study, we demonstrate that CD133 and a second marker CD15 are expressed heterogeneously in uniformly undifferentiated human neural stem (NS) cell cultures. After fractionation by flow cytometry, clonogenic tripotent cells are found in populations negative or positive for either marker. We further show that CD133 is down-regulated at the mRNA level in cells lacking CD133 immunoreactivity. Cell cycle

New Drugs On The Way To Fight Brain Cancer, Prostate Cancer

An experimental drug is on the way, which might be effective to fight brain cancer (glioblastoma) and prostate cancer.
The researchers are experimenting on this drug at the University of Texas Southwestern Medical Centre (UTSMC).
According to Jerry Shay, professor of cell biology, the drugs are promisisng because they attack not only the tumour cells but also the rare cancer stem cells in the body. So, it would be effective to root out cancer from the body.
“Because it attacks a mechanism that’s active in most cancers, it might prove to be widely useful, especially when combined with other therapies,” said Shay.
