\begin{Description}\relax
Human stem cells were assayed using Affymetrix 133plus 2 arrays. There
were six arrays, three were biological replicates for undifferentiated
cells, the other three were biological replicates for differentiated cells.
\end{Description}
\begin{Usage}
\begin{verbatim}data(fhesc)\end{verbatim}
\end{Usage}
\begin{Format}\relax
The data are in the form of an \code{ExpressionSet} instance.
\end{Format}
\begin{Details}\relax
Human Embryonic Stem Cells, H1 Line were cultured under feeder-free conditions.
Undifferentiated samples were taken from this pool. The differentiated samples
were obtained by maintaining the cells in culture for 10 - 14 days in the 
absence of basic fibroblast growth factor and conditioned medium.
