Here , we discuss the possibility for MMPs to contribute to pericyte recruitment at six levels : ( 1 ) direct promotion of pericyte invasion by extracellular matrix degradation ; ( 2 ) stimulation of pericyte proliferation and protection against apoptosis by modification of the ECM ; ( 3 ) activation of pericytes through the release of growth factor bound to the ECM ; ( 4 ) transactivation of angiogenic cell surface receptor ; ( 5 ) propagation of angiogenic signalling as cofactor ; and ( 6 ) recruitment of bone marrow - derived stem cells .
