Laser Capture Microdissection of Vascular Endothelial Cells from Frozen Heart Tissues.

Laser capture microdissection (LCM) enables researchers to selectively evaluate gene expression profiling of a specific cell type within a tissue. Vascular endothelial cells (EC) line the inside of vessel lumen and play an essential role in new blood vessel formation. It remains a challenge to determine vascular ECs-specific genes expression in vivo. Here, we described a method to dissect vascular ECs from the frozen heart tissue by LCM. The total RNA or proteins are then extracted from the ECs for further analysis.
