Isolated adult cells, artificial organs, rehabilitated organs, research tools, organ encasements, organ perfusion systems, and methods for preparing and utilizing the same
One aspect of the invention provides a method for harvesting adult cells from an organ. The method includes perfusing the organ with a perfusate and isolating adult cells from the organ, thereby harvesting the adult cells from the organ. Another aspect of the invention provides a method for rehabilitating an organ. The method includes: dividing the organ into a first portion and a second portion, perfusing the first portion with a decellularization medium, isolating adult cells from the second portion, and recellularizing the first portion with a suspension of the adult cells, thereby rehabilitating the organ.
1 . A method for harvesting adult cells from an organ, the method comprising:
(a) perfusing the organ with a perfusate comprising an enzymatic digestion agent and one or more anti-inflammatory agents, wherein the one or more anti-inflammatory agents comprise hydrocortisone;
(b) isolating the adult cells from the organ; and
(c) culturing the adult cells, thereby harvesting the adult cells from the organ.
2 . The method of claim 1 , wherein the organ is a mammalian organ.
3 . The method of claim 2 , wherein the organ is a human organ.
4 . The method of claim 1 , wherein the organ is one selected from the group consisting of: spleen, heart, lung, and kidney.
5 . The method of claim 1 , wherein the organ is ischemic and/or wherein the organ is a damaged organ.
6 . The method of claim 1 , wherein the perfusate includes one or more oxygen carriers, wherein the one or more oxygen carriers comprise erythrocytes.
7 . The method of claim 1 , wherein the enzymatic digestion agent comprises collagenase.
8 . The method of claim 7 , wherein the perfusate is a normothermic perfusate, a room temperature perfusate, or a hypothermic perfusate.
9 . The method of claim 7 , further comprising providing the organ.
10 . The method of claim 7 , further comprising filtering the perfusate through one or more mesh filters having pore sizes ranging from about 1 μm to about 1000 μm.
11 . The method of claim 7 , further comprising performing density centrifugation on the perfusate, or wherein the method further comprises circulating the perfusate through a dialyzer.
12 . The method of claim 7 , wherein the perfusing step improves vitality of the adult cells.
13 . The method of claim 1 , wherein the enzymatic digestion agent is selected from the group consisting of collagenase I, collagenase II, collagenase III, collagenase IV, collagenase V, collagenase VI, trypsin, and hyaluronidase.
