“…Similarly, our group could not effectively reprogram rASCs using the same protocols successfully applied in other species, such as dog, horse, bovine, and human. 47 – 50 The induced pluripotent stem cell (iPS)-like colonies vanished after few days, possibly due to the high proliferation of rASCs ( Figure S1A and B ). After cell cycle arrest and synchronization by serum starvation, we were able to reduce the proliferative rate of rASCs and improve the transduction and reprogramming ( Figure S1C–G ).…”

IntroductionOwing to their similarity with humans, rabbits are useful for multiple applications in biotechnology and translational research from basic to preclinical studies. In this sense, mesenchymal stem cells (MSCs) are known for their therapeutic potential and promising future in regenerative medicine. As many studies have been using rabbit adipose-derived MSCs (ASCs) as a model of human ASCs (hASCs), it is fundamental to compare their characteristics and understand how distinct features could affect the translation to human medicine.ObjectiveThe aim of this study was to comparatively characterize rabbit ASCs (rASCs) and hASCs to further uses in biotechnology and translational studies.Materials and methodsrASCs and hASCs were isolated and characterized by their immunophenotype, differentiation potential, proliferative profile, and nuclear stability in vitro.Results and discussionBoth ASCs presented differentiation potential to osteocytes, chondrocytes, and adipocytes and shared similar immunophenotype expression to CD105+, CD34−, and CD45−, but rabbit cells expressed significantly lower CD73 and CD90 than human cells. In addition, rASCs presented greater clonogenic potential and proliferation rate than hASCs but no difference in nuclear alterations.ConclusionThe distinct features of rASCs and hASCs can positively or negatively affect their use for different applications in biotechnology (such as cell reprogramming) and translational studies (such as cell transplantation, tissue engineering, and pharmacokinetics). Nevertheless, the particularities between rabbit and human MSCs should not prevent rabbit use in preclinical models, but care should be taken to interpret results and properly translate animal findings to medicine.
