•The animal models of spontaneous renal carcinoma have been very useful especially in the second part of the twentieth century to better understand the pathophysiology of human renal ...carcinomas.•Studies performed in the Eker rat and the Nihon rat models have shown in particular that renal carcinogenesis could happen in 2 phases as per the Knudson's 2 hits theory.•Recent research advances performed in humans have very recently highlighted how one metastatic kidney cancer actually regrouped a subset of subclones generated by the occurrence of truncal and subsequent branch mutations.•In this context, we believe the animal models of spontaneous renal carcinoma could help fine tune our understanding of the mechanisms underlying this genetic cascade.
Introduction and Objectives The animal models for renal carcinogenesis have allowed researchers to better understand the physiopathological, genetic, molecular, and immunological mechanisms underlying the development of human renal cancers from the induction of precancerous lesions to the metastatic process. Our study aimed to review and discuss the characteristics of all the spontaneous animal models of renal carcinogenesis described in scientific literature to date and see how they could address future challenges in the field of personalized medicine. Methods and Materials We reviewed all the papers on PubMed which focus on spontaneous animal models of renal carcinogenesis. To do so, we used the keywords “spontaneous” AND “animal model” AND “renal cancer” in the PubMed search engine. We also conducted a search using the keywords “spontaneous” AND “animal model” AND “kidney cancer.” PRISMA recommendations were used for the literature review. Results A total of 213 publications were found on PubMed with the keywords “spontaneous” AND “animal model” AND “kidney cancer.” 219 publications were found on PubMed with the keywords “spontaneous” AND “animal model” AND “renal cancer.” After pooling these 2 searches and removing the duplicate publications, 233 publications remained. Among these, 220 full-text articles were assessed for eligibility; 160 were removed because they were irrelevant to our topic, and the remaining 60 studies were included in our qualitative synthesis. Conclusions Many spontaneous animal models have been developed to study renal cancer. So far, these models have enabled the understanding of pathophysiological mechanisms underlying renal cancer. Though less appropriate than patient xenografts from the perspective of personalized medicine, we believe animal models can help medical professionals better understand the hows and whys of the genetic events underlying the intratumoral heterogeneity and spatial distribution of metastatic subclones.

Minimally-invasive autologous fat injection of the head and neck region can be considered a valid alternative to major invasive surgical procedures both for aesthetic and functional purposes. The ...favourable outcomes of autologous fat injection in otolaryngological practice are due to the filling of soft tissue and, mainly, to the potential regenerative effect of adipose-derived mesenchymal stem cells. Herewith, some important biological preliminary remarks are described underlying the potential of autologous fat injection in regenerative medicine, and personal experience in using it for both consolidated clinical applications, such as fat grafting to the face and vocal fold augmentation in the treatment of glottic incompetence, and more recent applications including the treatment of post-parotidectomy Frey syndrome and velopharyngeal insufficiency.
