Cellular attachment to trans-epithelial appliances

摘要

A trans-epithelial appliance having a hemidesmosome formation-inducing protein composition derived from rat bladder carcinoma cells deposited thereon. This composition stimulates cell attachment and may be either the cell matrix or a soluble factor isolated from the conditioned medium. The appliance will be useful for diminishing inflammation and/or infection at the site of entry of the appliance. The appliance may also be used to stimulate gum junctional epithelium adhesion in the treatment of gingivitis and periodontitis. The composition may be used to maintain tissues ex vivo.
