Healing of wounds in mammalian tissue may be enhanced by the application of certain neuropeptides, optionally in combination with known growth promoting hormones. Exemplary neuropeptides include tachykinins, such as substance P, substance K, and the like, as well as calcitonin gene-related peptides. The compositions include a carrier or vehicle suitable for topical application and are utilized by applying to the site of the wound. Wounds resulting from trauma, surgery, and disease may be treated. The compositions promote elaboration of cellular matrices and development of cellular attachment mechanisms in addition to stimulating cellular proliferation.
