Embryonic stem (ES) cells hold promise to treat a variety of disease. The major obstacle is to determine the requirements that will drive these cells to a particular lineage. Two approaches to examine lineage commitment are the addition of growth factors or directed differentiation of ES cells. Although many neural genes have been identified, the cascade of gene expression that directs neural differentiation is not well understood. Today, with microarray technology, large data sets of differential gene expression patterns are used to identify genes that may be used as indicators of a particular cell lineage or tissue type. Semiquantitative polymerase chain reaction (PCR) can be carried out to verify the expression of individual genes, followed by quantitative PCR to precisely determine the level of mRNA expression. However, functional analysis of potential neurogenic genes must be done to identify those genes that play a critical role in neural lineage commitment.
