During a pre-clinical testing process, developing new therapies for damaged tissues or diseases should be evaluated by using in vitro cell testing and in vivo animal studies. The ex vivo models bring hope to provide a 3D biomimetic environment to bridge the gap between in vitro cell testing and in vivo animal studies. Therefore, ex vivo testings enable offering a promising to provide more confident results in preclinical testing. Adipose-derived stem cells and induced pluripotent stem cells (iPSCs) are two stem cells that have been widely used in regenerative medicine field. iPSC-derived products intended for clinical use should be used in pre-clinical studies. Immunosuppressed or immunocompromised animals should be studied to prevent human cell rejection in animal studies.book part10.1201/9781003130048-92-s2.0-85178637747https://api.elsevier.com/content/abstract/scopus_id/85178637747
