Angiogenesis
Definition
The growth of new blood vessels from existing vessels. It occurs in normal tissue repair and in some diseases.

Why the context matters
A report of angiogenesis describes a biological process, not a clinical verdict. Location and purpose matter: new vessels may support repairing tissue, while a tumor can also recruit a blood supply. Calling a compound pro-angiogenic therefore does not establish that it heals an injury or is safe for a particular patient.

How to read a study
If a study reports more vessel staining in a treated tendon, first identify the species, injury model and comparison group. Next look for a separate functional outcome, such as load tolerance or recovery of movement. More staining and better function answer different questions; neither automatically establishes a human treatment benefit.
Common misconception
Angiogenesis is not the same as an increase in blood flow through vessels that already exist. A biomarker associated with vessel growth is also not proof that new, useful vessels formed. Check what investigators actually measured before applying the label.
