Efforts in medicine and tissue engineering have shown that the production of human tissues and organs within compounds of human-animal cells is possible through a technique called interspecific blastocyst complement. The creation of human-animal chimeras allows the medical world to test some of the common features of humans, namely their stem cells, in the bodies of other living things. Among regenerative/reconstructive medicine’s significant achievements are numerous benefits, including the production of human organs in animals and their ultimate use in organ transplant surgery. This article uses an analytical approach to explain this vital technology’s legal regime. Since human essence and soul are divine, and inherent dignity governs the bondage of living human cells from birth, the legal challenges to hybrid human which contain cellular composition, seem to be due to this gift, namely. The description of being human is of particular importance that should be considered in modern medical and tissue engineering approaches.
