Abstract
A homogenous, symmetrically dividing population of adherent neural stem cells is obtained from ES cells or foetal or adult brain isolates, using an activator of a signalling pathway downstream of a receptor of the EGF receptor family, optionally in combination with an activator of a signalling pathway downstream of an FGF receptor. The neural stem cell population is highly pure and retains the ability to differentiate into neurons after in excess of 100 passages.

A composition, comprising neural stem cells;
- wherein at least 80% of said cells are symmetrically dividing neural stem cells and wherein no more than 1% of the cells are positive for the expression of markers from mature astrocytes, neurons and oligodendrocytes.
A cell line, wherein at least 80% of said cells are symmetrically-dividing neural stem cells and wherein no more than 1% of the cells are positive for the expression of markers for mature astrocytes, neurons, and oligodendrocytes.
A composition comprising neural stem cells, wherein at least 95% of the cells in the composition are symmetrically-dividing neural stem cells.
