It is illustrated fro an unbelievable picture in BBC news that a sort of artificial ear is available in live rat. And experts also assert that liver can be implanted in the similar way. Perhaps, from an ordinary people's perspective, the appearance of the testees tend to looks very eccentric creatures which always arise in science fiction movies.

It is undiable that artificial tissues of animals may have positive effects on our lives in several aspects. Due to increasing demands of people's transplant resource,experts have responsibilities to find solutions to potential substitutes. Thus, exploitation of mammals such as rats trigger a great improvement of artificial tissues in medical service. Abviously, the material of the experiment need to be proved by biological testing. Moreover, many neglect the weakness that threr is no solution to ensure these implants disinfected.

In summary,I tend to hlod a rosy attitude that implants of animals will definately make contribution in reality after experts overcome the related current problems.
