Abstract

The invention relates generally to the fields of biology and life sciences. More particularly, the invention relates to compositions and methods for modulating cellular physiology and pathological processing using a combination of compounds that can be found in morselized amniotic membrane tissue and morselized umbilical cord tissue preparations.

Claims (35)

1. A method for treating an ocular wound or repairing damaged ocular tissue in an individual in need thereof, comprising: administering to the individual a therapeutically effective amount of a gel composition comprising:

a) a therapeutically effective amount of i) morselized placental amniotic membrane and ii) morselized umbilical cord; and

b) a pharmaceutically-acceptable excipient;

wherein the morselized placental amniotic membrane and the morselized umbilical cord have a particle size of between about 0.1 mm to about 1.0 cm in length, width, and thickness.

2. The method according to claim 1 , wherein the individual has a glaucoma-induced ocular wound, glaucoma-induced ocular tissue damage, an ocular ulcer, a corneal ulcer, a conjunctival reconstruction, a scleral reconstruction, a lid reconstruction, or an orbital rim reconstruction.

3. The method according to claim 1 , wherein the composition has a reduced water content by weight percentage compared to the morselized placental amniotic membrane or the morselized umbilical cord before morselization.

4. The method according to claim 1 , wherein the composition has a water content greater than 20% by weight percentage compared to the morselized placental amniotic membrane or the morselized umbilical cord before morselization.

5. The method according to claim 1 , wherein the composition is sterilized.

6. The method according to claim 5 , wherein the composition is sterilized by gamma (γ) radiation.

7. The method according claim 1 , wherein the morselized placental amniotic membrane and the morselized umbilical cord have a biological activity that is substantially preserved for at least 15 days after initial procurement.

8. The method according to claim 1 , wherein the composition is anti-inflammatory, anti-scarring, anti-angiogenic, anti-adhesion, or promotes wound healing.

9. The method according to claim 1 , wherein the morselized placental amniotic membrane and the morselized umbilical cord substantially do not comprise red blood cells.

10. The method according to claim 1 , wherein the morselized placental amniotic membrane substantially does not comprise chorion.

11. The method according to claim 1 , wherein the morselized placental amniotic membrane comprises chorion.

12. The method according to claim 1 , wherein the composition further comprises amniotic fluid.

13. The method according to claim 1 , wherein the morselized placental amniotic membrane, morselized umbilical cord or combination thereof is cryopreserved, lyophilized, or a combination thereof.

14. The method according to claim 1 , wherein the composition further comprises at least one pharmaceutically acceptable carrier or diluent selected from the group consisting of: acacia, gelatin, colloidal silicon dioxide, calcium glycerophosphate, calcium lactate, maltodextrin, glycerine, magnesium silicate, polyvinylpyrrollidone (PVP), cholesterol, cholesterol esters, sodium caseinate, soy lecithin, taurocholic acid, phosphotidylcholine, sodium chloride, tricalcium phosphate, dipotassium phosphate, cellulose and cellulose conjugates, sugars sodium stearoyl lactylate, carrageenan, monoglyceride, diglyceride, pregelatinized starch, lactose, starch, mannitol, sorbitol, dextrose, microcrystalline cellulose, dibasic calcium phosphate, dicalcium phosphate dihydrate; tricalcium phosphate, calcium phosphate; anhydrous lactose, spray-dried lactose, compressible sugar, hydroxypropylmethylcellulose, hydroxypropylmethylcellulose acetate stearate, sucrose, confectioner's sugar; monobasic calcium sulfate monohydrate, calcium sulfate dihydrate; calcium lactate trihydrate, dextrates; hydrolyzed cereal solids, amylose; powdered cellulose, calcium carbonate; glycine, kaolin; sodium chloride, inositol, and bentonite.

15. The method according to claim 1 , wherein the morselized placental amniotic membrane, morselized umbilical cord or combination thereof is a homogenate.

16. A method for treating an ocular wound or repairing a damaged ocular tissue in an individual in need thereof, comprising: applying to the individual an apparatus comprising (a) an inert support, and (b) a gel composition comprising morselized placental amniotic membrane, morselized umbilical cord, or a combination thereof;

wherein the morselized placental amniotic membrane and the morselized umbilical cord have a particle size of between about 0.1 mm to about 1.0 cm in length, width, and thickness.

17. The method according to claim 16 , wherein the individual has a glaucoma-induced ocular wound, glaucoma-induced ocular tissue damage, an ocular ulcer, a corneal ulcer, a conjunctival reconstruction, a scleral reconstruction, a lid reconstruction or an orbital rim reconstruction.

18. The method according to claim 16 , wherein the morselized placental amniotic membrane, morselized umbilical cord or combination thereof has a reduced water content by weight percentage compared to the morselized placental amniotic membrane or the morselized umbilical cord before morselization.

19. The method according to claim 18 , wherein the morselized placental amniotic membrane, morselized umbilical cord or combination thereof has a water content greater than 20% by weight percentage.

20. The method according to claim 16 , wherein the apparatus is sterilized.

21. The method according to claim 20 , wherein the apparatus is sterilized by gamma (γ) radiation.

22. The method according to claim 16 , wherein the inert support is a mesh sheet with an average pore size of about 0.2 mm to about 0.9 cm.

23. The method according to claim 22 , wherein the inert support comprises a material selected from the group consisting of: collagen; hydrogels; keratin; hydrophilic polyurethane; polyethylene glycols; poly(lactic-co-glycolic acids); and hydrocolloids.

24. The method according claim 16 , wherein the morselized placental amniotic membrane and the morselized umbilical cord have a biological activity that is substantially preserved for at least 15 days after initial procurement.

25. The method according to claim 16 , wherein the apparatus is anti-inflammatory, anti-scarring, anti-angiogenic, anti-adhesion, or promotes wound healing.

26. The method according to claim 16 , wherein the morselized placental amniotic membrane and the morselized umbilical cord substantially do not comprise red blood cells.

27. The method according to claim 16 , wherein the morselized placental amniotic membrane substantially does not comprise chorion.

28. The method according to claim 16 , wherein the morselized placental amniotic membrane further comprises chorion.

29. The method according to claim 16 , wherein the apparatus further comprises amniotic fluid.

30. The method according to claim 16 , wherein the morselized placental amniotic membrane, morselized umbilical cord or combination thereof is cryopreserved, lyophilized, or a combination thereof.

31. The method according to claim 16 , wherein the morselized placental amniotic membrane, morselized umbilical cord or combination thereof is a homogenate.
