Abstract

In this study, we successfully transferred the Escherichia coli β‐galactosidase gene, LacZ, into the chicken tendon and tendon sheath by a recombinant adenovirus. The recombinant adenovirus Adv‐βgal that carried the E. coli LacZ gene was constructed by homologous recombination in 293 cells (human transformed embryonic kidney) between the expressing vector and the ClaI large fragment of adenovirus 5 genome. Each chicken received a 10 μl injection, containing 10^5^ plaque‐forming units of recombinant virus Adv‐βgal, into the tendon sheath of the long toe. Samples of tendon and tendon sheath were harvested at 3, 30, and 75 days after the injection. The LacZ gene transfer was detected for its coding product β‐galactosidase by staining with X‐gal solution. The results showed that all tendon and tendon sheath samples from the three harvest times stained positive (blue). The tendon sheath samples were more extensively stained; staining of the tendon was limited to the epitenon layer. These data suggest that a functional exogenous gene can potentially be transferred into the tendon and tendon sheath by similar techniques; such techniques may be used to improve healing and reduce adhesion formation.

## Abstract ## Background Degenerative or traumatic tendon injuries are extremely common but often heal poorly, not restoring the normal function of the injured tissues. Gene transfer could improve the repair process, by permitting local production of therapeutic substances, e.g. growth factors.

Adhesion formation is a frequent complication of tendon injury repair: however, little is known about its mechanisms. The intracellular focal adhesion kinase (FAK)-related signaling pathway may be one of the mechanisms involved in the induction of tendon adhesions. The replication deficient adenovir

We used recombinant adenoviruses as a means of expressing exogenous genes in olfactory neurons in vivo. A replication incompetent adenovirus (type 5, Ad5) carrying the reporter gene lacZ, which codes for the enzyme 8-galactosidase (,&Gal), was applied in solution to the olfactory epithelia of rats.
