Protein could improve recovery from heart attacks

Angiogenesis is required during embryonic development and wound healing, as well as during disease processes such as tumor growth. The signals that direct angiogensis could represent novel targets for the development of therapies. A new paper reveals that two related proteins -- DKK1 and DKK2 -- play opposite roles in directing angiogenesis. Remarkably, injection of DKK2 improved vascular regeneration in a mouse model of myocardial infarction (heart attack).
