Abstract

An autologous cell therapy product composed of fibroblasts grown for each individual to be treated for vocal cord scarring. The suspension of autologous fibroblasts, grown from a biopsy of each individual's own buccal mucosa or skin using current good manufacturing practices (CGMP) and standard tissue culture procedures, is supplied in cryovials containing cryopreserved autologous fibroblasts or precursors thereof, at a concentration of between 1.0×10 7 cells/mL and 2.7×10 7 cells/mL, wherein at least 85% of the human fibroblast cells are viable after freezing and thawing.

Claims (24)

1. A cryovial containing an autologous fibroblast product comprising:

from about one mL to six mL of autologous human fibroblast cells, or precursors thereof, obtained from buccal mucosa of a human, at a concentration of between 1.0×10 7 cells/mL and 2.7×10 7 cells/mL, wherein at least 85% of the human fibroblast cells are viable after freezing and thawing; and

a cryopreservation medium, wherein the autologous fibroblast product is for treatment of vocal cord scarring.

2. The cryovial of claim 1 wherein the cryopreservation medium consists of Iscove's Modified Dulbecco's Medium, and 7.5% dimethylsulfoxide.

3. The cryovial of claim 1 wherein the cryovial is frozen.

4. The cryovial of claim 3 wherein the cryovial is frozen at 2-8° C.

5. The cryovial of claim 1 wherein a cap of the cryovial and a container of the cryovial are radiation sterilized.

6. The cryovial of claim 1 wherein the cryovial comprises a volume of 1.2 mL of autologous human fibroblast cells, or precursors thereof, at a concentration of between 1.0×10 7 cells/mL and 2.7×10 7 cells/mL.

7. The cryovial of claim 1 wherein the cryovial is free of mycoplasma.

8. The cryovial of claim 1 wherein the cryovial is free of endotoxin.

9. A cryovial containing an autologous fibroblast product comprising:

from about one mL to six mL of autologous human fibroblast cells, or precursors thereof, obtained from buccal mucosa of a human at a concentration of between 3.0×10 7 cells/mL and 4.0×10 7 cells/mL, wherein at least 85% of the human fibroblast cells are viable after freezing and thawing; and

a cryopreservation medium, wherein the autologous fibroblast product is for treatment of vocal cord scarring.

10. The cryovial of claim 9 wherein the cryopreservation medium consists of Iscove's Modified Dulbecco's Medium, and 7.5% dimethylsulfoxide.

11. The cryovial of claim 9 wherein the cryovial is frozen.

12. The cryovial of claim 11 wherein the cryovial is frozen at 2-8° C.

13. The cryovial of claim 9 wherein a cap of the cryovial and a container of the cryovial are radiation sterilized.

14. The cryovial of claim 9 wherein the cryovial is free of mycoplasma.

15. The cryovial of claim 9 wherein the cryovial is free of endotoxin.

16. A cryovial containing an autologous fibroblast product comprising:

from about one mL to six mL of autologous human fibroblast cells, or precursors thereof, obtained from buccal mucosa of a human at a concentration of between 1.0×10 7 cells/mL and 2.7×10 7 cells/mL, wherein at least 85% of the human fibroblast cells are viable after freezing and thawing; and

a cryopreservation medium that consists of Iscove's Modified Dulbecco's Medium, and 7.5% dimethylsulfoxide, wherein the cryovial is frozen, wherein the autologous fibroblast product is for treatment of vocal cord scarring.

17. The cryovial of claim 16 wherein the cryovial is frozen at 2-8° C.

18. The cryovial of claim 16 wherein the cryovial comprises a volume of 1.2 mL of autologous human fibroblast cells, or precursors thereof, at a concentration of between 1.0×10 7 cells/mL and 2.7×10 7 cells/mL.
