Figure 2From: The CNS microvascular pericyte: pericyte-astrocyte crosstalk in the regulation of tissue survivalCapillaries [2-6 micron diameter determined by Image J software] were isolated from wild type C57BL/6 mice (A), GFAP -/+ mice (B), and GFAP -/- mice (C) (Jackson Laboratory). Freshly isolated capillaries were allowed to adhere to coverslips fixed and stained for the expression of GFAP (Santa Cruz Biotechnology Inc). Capillaries were visualized on a Leitz fluorescent microscope at 40× and 100×.Back to article page
