Activated leukocyte conditioned supernatant and uses for wound healing
First Claim
Patent Images
1. A substantially cell-free activated leukocyte-conditioned supernatant (ALCS), wherein the ALCS is made by:
- incubating human leukocytes under conditions of time and temperature to activate the leukocytes, wherein the activated leukocytes comprise activated granulocytes, activated monocytes, and activated lymphocytes;
subjecting the activated leukocytes to hypo-osmotic shock;
adding to the activated leukocytes subjected to the hypo-osmotic shock to a physiologically acceptable solution containing inorganic ions, organic osmolytes, or a combination thereof in an amount which restores isotonicity;
separating the activated leukocytes from the resulting isotonic solution;
mixing the separated activated leukocytes with a medium to form an incubation composition;
incubating the incubation composition (i) at room temperature for 8 to 72 hours;
or (ii) at about 37°
C. for 3 to 5 hours; and
separating the activated leukocytes and other cellular matter from the incubation composition to produce a substantially cell-free ALCS.
