The blood–brain barrier is formed by the brain capillary endothelium and plays a neuroprotective role in healthy brain function. For researchers studying gene expression within the central nervous system vasculature, endothelial heterogeneity can pose a challenge. Whole tissue samples—homogenates of brain and or spinal cord, for example—are composed of multiple endothelial cell types from different regions of the CNS, resulting in a pooling of cells and an unclear characterization of endothelial cell subtypes.
The ArcturusXT™ Laser Capture Microdissection System enables gentle, selective isolation of specific cells from heterogeneous tissue, protecting biomolecule integrity and allowing researchers to uncover hidden molecular signals, revealing more accurate profiles of highly complex neurovasculature.

Dr. Joel Pachter, Professor of Cell Biology at the University of Connecticut Health Center, discusses the genetic profiling of microvessels to monitor progression of inflammatory disease. Learn how Dr. Pachter used the Life Technologies™ LCM/qPCR workflow to explore the development of pharmacotherapies to address diseases associated with the blood–brain barrier.
