Laser capture microdissection (LCM) provides an efficient and precise method for the sampling of single cells or subgroups
of cells in heterogeneous tissues such as the brain. We have recently applied LCM coupled with microarray analysis for the
examination of gene expression in the hypothalamic arcuate nucleus of free fed versus fasted rats. We successfully used QPCR
analysis to validate our findings and to confirm the regulation of several known neuropeptides. We show that the combination
of LCM and QPCR analysis provides a reliable, fast, and efficient alternative to semiquantitative in situ hybridization analysis
of gene expression.
