SASP is the Senescence Associated Secretory Phenotype – this is the name for the compounds secreted by senescent cells. There are over 500 known senescent cell secretions. One of the commonly know functions of SASP is to create inflammation to initiate wound healing. This type of function is present, not only for wounds but damage like; sunburns, broken bones, and other forms of trauma. Once these immortal cells are created and their usefulness ends, they do not die and they do not stop secreting SASP.
