    The common octopus, Octopus vulgaris, can regenerate fully functional arms that are lost or damaged within several weeks, and severe wounds can heal within a few hours. We noticed that fallowing amputation of an arm, the octopus exhibits an interesting behavior of inserting the stump into its mouth, possibly exposing the wound to its saliva. Indeed, our preliminary research reveals significant increase in arm regeneration rate and wound healing following exposure of the stump to saliva.
    Our goal in this study is to characterize the mechanism underlying the effect of saliva on the regeneration and healing processes. 
    Our Approach and methodology: First we will characterize differences in gene expression and changes in protein content pattern, before and after amputation, in stumps that were exposed or avoided from the saliva. Then, we will try to understand the role of these genes and proteins in the regeneration process probably using relevant pharmacology.
    We will test the saliva effects using an octopus as a specific model and planarian as a more standard and acceptable model for regeneration. 
    In general, we will use in this research molecular and bioinformatics tools, HPLC and basic methods for protein characterization, microscopy and image processing tools.
    * Working with animals, under anesthesia and in accordance with accepted ethical rules are mandatory conditions for this research.
    In addition to the fundamental scientific contributions, the findings of this research hold medical and applied potential for the identification of novel lead compounds and the development of new therapeutic agents. Furthermore, the insights gained can enhance our understanding of processes that may contribute to the advancement of treatments aimed at improving wound healing.
