What are the advantages of using pro-angiogenic peptides instead of cytokines like VEGF to enhance vessel formation after MI? Despite having similar preservation conditions, the function of cytokines is stronger and clearer.

Possible revised version:

Why choose pro-angiogenic peptides over cytokines like VEGF for enhancing vessel formation after MI? Despite similar preservation requirements, peptides offer distinct advantages, such as greater specificity, longer half-life, and reduced side effects, compared to cytokines whose function may be stronger but also less selective and more prone to adverse reactions.
