摘要

An improved method for culturing primary rat brain capillary endothelial cells on glass has been developed, using a corneal extracellular matrix coat. Since the collagen-coated plastic attachment surface conventionally used for primary cultures of brain microvascular endothelium gives a high level of background fluorescence in microfluorimetric studies, an alternative attachment surface was tested involving no plastic element. Five substrata combinations were examined and a new combination of glass and corneal endothelial extracellular matrix coat was found to provide excellent cell adhesion, culture growth and purity. Other established substrata combinations tested for comparison, either involved plastic, or used glass with collagen or carbodiimide and collagen coating but the last two gave poor endothelial cell adhesion and growth. Our method using this new attachment surface combination results in stable and pure endothelial cultures, as verified by immunocytochemistry, which are suitable for fluorimetric investigations.
