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 1.0×107 cells/mL and 2.7×107 cells/mL, wherein at least 85% of the human fibroblast cells are viable after freezing and thawing.
Claims18
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 1.0×107 cells/mL and 2.7×107 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.
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 3.0×107 cells/mL and 4.0×107 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.
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 1.0×107 cells/mL and 2.7×107 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.
