Therapeutics using adipose cells and cell secretions
The invention relates to compositions comprising (i) adipose tissue-derived cell secretions or (ii) an adipose tissue-derived cell suspension, optionally comprising adipocytes, or (iii) a combination of adipose tissue-derived cell secretions and an adipose tissue-derived cell suspension, optionally comprising adipocytes, and to their use in pharmaceutical compositions and methods for treatment of various conditions. The invention also relates to improved methods, agents and compositions for cryopreservation of cells.
1. A method of alleviating pain in a mammalian subject, the method comprising,
administering to the subject a pharmaceutical composition which comprises a combination of adipose tissue-derived cell secretions and multiply-passaged adherent cells from an adipose tissue-derived cell suspension,
wherein said adipose tissue-derived cell secretions are prepared by culturing multiply-passaged adherent progeny cells from an adipose tissue-derived cell suspension and harvesting supernatant from the cell culture after about 3 or more days,
said adherent progeny cells having a fibroblast-like appearance, and
wherein said combination has been cryopreserved.
2. The method according to claim 1 , wherein said administration to said subject is by intra-articular injection or by intramuscular injection or by subcutaneous injection or by topical administration.
3. The method according to claim 1 , wherein the pain is back pain, or is pain associated with a burn injury, an inflammatory disorder, a ligament injury, a tendon injury, or the sciatic nerve, or is neuropathic pain.
4. The method according to claim 3 , wherein the neuropathic pain is facial pain, pain of the teeth, jaw, gum or of a limb.
5. The method according to claim 1 , wherein the adipose tissue-derived cell suspension (i) comprises adipocytes or (ii) is substantially free of adipocytes.
6. The method according to claim 1 , wherein the subject is selected from the group consisting of (i) a human, (ii) poultry, (iii) an equine animal, (iv) a feline animal, (v) a canine animal, (vi) a bovine animal, and (vii) a porcine animal.
7. The method according to claim 1 , wherein the adipose tissue-derived cell secretions or the adipose tissue-derived cell suspension is (i) derived from adipose tissue allogeneic to the recipient subject or animal, or (ii) derived from the intended recipient subject or animal, or (iii) derived from adipose tissue xenogeneic to the recipient subject or animal.
8. The method according to claim 1 , wherein the adipose tissue-derived cell secretions is a preparation concentrated by between 2-fold and 20-fold.
9. The method according to claim 1 , wherein said adipose tissue-derived cell secretions comprises concentrated media from culture of an adipose tissue-derived cell suspension, optionally wherein said adipose tissue-derived cell suspension (i) comprises adipocytes and adipose tissue-derived mesenchymal stem cells or (ii) is substantially free of adipocytes, optionally wherein said media from culture of an adipose tissue-derived cell suspension is concentrated between 2-fold and 20-fold.
10. The method according to claim 1 , wherein the method further comprises thawing the cryopreserved combination prior to administration to the recipient subject or animal.
11. The method according to claim 10 , wherein the cryopreserved combination, or pharmaceutical composition thereof, is administered to the recipient subject or animal within two hours of thawing.
12. A kit comprising (a) a pharmaceutical composition comprising a combination of adipose tissue-derived cell secretions and multiply-passaged adherent cells from an adipose tissue-derived cell suspension, wherein said adipose tissue-derived cell secretions are prepared by culturing multiply-passaged adherent progeny cells from an adipose tissue-derived cell suspension and harvesting supernatant from the cell culture after about 3 or more days, said adherent progeny cells comprising cells having a fibroblast-like appearance, wherein said combination or composition is cryopreserved; and (b) instructions for use of said kit in alleviating pain in a mammalian subject.
13. The kit according to claim 12 , wherein the pain is back pain, or is pain associated with a burn injury, an inflammatory disorder, a ligament injury, a tendon injury, or the sciatic nerve, or is neuropathic pain, optionally wherein the neuropathic pain is facial pain, pain of the teeth, jaw, gum or of a limb.
14. The kit according to any claim 12 , wherein the adipose tissue-derived cell suspension (i) comprises adipocytes, or (ii) is substantially free of adipocytes.
15. The kit according to claim 12 , further comprising instructions for administration of said composition within 2 hours of thawing said cryopreserved composition.
16. The kit according to claim 12 , wherein the adipose tissue-derived cell secretions or the adipose tissue-derived cell suspension is (i) derived from adipose tissue allogeneic to the recipient subject or animal, or (ii) derived from the intended recipient subject or animal, or (iii) derived from adipose tissue xenogeneic to the recipient subject or animal.
17. The kit according to claim 12 , wherein the adipose tissue-derived cell secretions is a preparation concentrated by between 2-fold and 20-fold.
18. The kit according to claim 12 , wherein said adipose tissue-derived cell secretions comprises concentrated media from culture of an adipose tissue-derived cell suspension, optionally wherein said adipose tissue-derived cell suspension (i) comprises adipocytes and adipose tissue-derived mesenchymal stem cells or (ii) is substantially free of adipocytes, optionally wherein said media from culture of an adipose tissue-derived cell suspension is concentrated between 2-fold and 20-fold.
