What happens after tissue injury? Inflammation, repair and angiogenesis explained.
Tissue injury initiates overlapping phases of inflammation, cell migration, matrix remodelling and vascular change. Researchers study these processes in cell, animal and human models; the timing and result depend on tissue, injury and experimental design.

What is inflammation?
Inflammation is a coordinated immune and vascular response; it is not automatically synonymous with healing or disease.
How does angiogenesis relate to repair?
Angiogenesis is new-vessel formation. Researchers examine when it supports oxygen delivery and when abnormal vascular signalling contributes to pathology.
What is the extracellular matrix?
The extracellular matrix provides structural and signalling context. Collagens, proteoglycans and remodelling enzymes change during repair.

Reference questions
Does inflammation always help repair?
No. It can be necessary for defence and repair, but duration, intensity and context matter.
Do these mechanisms prove a peptide treatment works?
No. Mechanistic plausibility and preclinical observations do not establish human efficacy or safety.
