Modified microbially-produced cellulose gel with human epidermal cells adsorbed thereon for use as a skin graft or vulnerary cover |
摘要 |
Disclosed is a gel of microbially-produced cellulose, characterized in that the microbially-produced cellulose is modified by (1) physically or chemically bonding an animal cell adhesive protein to the cellulose, and/or (2) substituting hydrogen atoms of at least parts of hydroxyl groups of the cellulose with a positively or negatively charged organic group. This gel is valuable as a carrier for mass culture of animal cells or as a medical vulnerary cover.
