Fig. 2From: Hydrogel based tissue engineering and its future applications in personalized disease modeling and regenerative therapyVarious animal models used for research and therapeutic studies: Xenopus, rodent, rabbit, and fish mostly preferred because of their small size, easy maintenance in laboratories, small gestation period, and a high number of live young. Genetic similarity between these organisms and humans makes them a preferable choice as human disease models. Pig and Monkey are used in research due to their organ size, and structure. The development of new genome modification tools resulted in regaining the interest of researchers towards large size non-rodent and non-human speciesBack to article page
