Full textPluripotent stem cells (PSCs) can self-renew at two distinct states, the naive and primed states. Many differences exist between these two states, the most striking is the unique ability of PSCs naïve to colonize the preimplantation embryo and form chimeras. The purpose of my doctoral project was to study pluripotency in rabbits. In this context, I initially manufactured and characterized induced pluripotent stem cells (RbiPSCs) and then evaluated their ability to colonize the embryo and form chimeras. Three RbiPSCs lines were obtained by rabbit fibroblasts reprogramming. Their molecular characterization revealed mixed characteristics, naïve and primed. However, functionally, they are unable to colonize the rabbit embryo, a feature of primed pluripotency. The second part of my doctoral project was to reprogram RbiPSCs to the naïve state. To this end, I have overexpressed Klf2 and Klf4, two genes belonging to the naïve pluripotency network and the mouse PSCs culture conditions. These new cell lines have a gene expression profile closer to that of the rabbit ICM, particularly due to the reactivation of specific markers of naïve pluripotency. Finally, the reverted cells have an increased capacity of colonization of the preimplantation embryo rabbit. My work represents the first example of pluripotent stem cells reprogramming toward the naive state in rabbits. The cells thus produced pave the way for the production of somatic and germline chimeras

Full textThe rex rabbit trait “autosomal recessive” induces a plush-like fur essentially composed of awn hair with high economic value (the coat is orylag®). The rex gene was identified on the chromosome 14, this gene is LIPH. By sequencing this gene, a deletion of one nucleotide in exon 9 (1362delA) was identified in a homozygous state in the rex rabbits. The mutation was found in total association with the rex phenotype. We shown by qPCR that in rex rabbits skin the expression level of LIPH is 3 times less than that observed in the wild phenotype since the three critical fetal stages of hair genesis with no apparent interference on follicle development. These results were confirmed by in situ hybridization and immunochemistry analysis on skin cross-sections. We also bring evidence that LIPH is not much expressed in the IRS (Internal Root Sheath) of the hair follicles in the rex and orylag® rabbits. We have also shown that the mutant protein has a reduced activity of 1. 5 compared to the wild one. These results contribute to the characterization of the metabolism of the hair follicle for which rabbit is an excellent model. They draw lines of reflexion for developments in humans and for selection criteria to improve the fur quality of orylag® rabbits
