From: Angiogenesis precedes myogenesis during regeneration following biopsy injury of skeletal muscle
The microcirculation regenerates through angiogenesis. A At 7 dpi, nascent microvessels emigrate centripetally from existing vasculature at wound edge. B At 7 dpi, microvessels are nonuniform in diameter and extend into the wound with random orientation. C Angiogenesis at 10 dpi is integral to revascularization. D Sites of robust angiogenic activity at 10 dpi create irregular microvascular plexuses. E Regenerating microvascular networks expand at 14 dpi. Images are from Cdh5-mTmG mice in which ECs are green (GFP) and all other cells are red (tdTomato)
