A protocol for phenotypic detection and characterization of vascular cells of different origins in a lung neovascularization model in rodents.

abstract：:Surface- and matrix-bound signals modulate stem cell fate in vivo and in vitro. This protocol enables the immobilization of a wide range of biomolecules that contain primary amino groups to different types of solid carriers, including glass substrates and standard polystyrene well plates. We describe how thin polymer ...
