Abstract
Hutchinson–Gilford progeria syndrome (HGPS) is a segmental premature aging disease caused by a mutation in LMNA. The mutation generates a truncated and farnesylated form of prelamin A, called progerin. Affected individuals develop several features of normal aging, including lipodystrophy caused by the loss of general subcutaneous fat. To determine whether premature cellular senescence is responsible for the altered adipogenesis in patients with HGPS, we evaluated the differentiation of HGPS skin-derived precursor stem cells (SKPs) into adipocytes. The SKPs were isolated from primary human HGPS and normal fibroblast cultures, with senescence of 5 and 30%. We observed that the presence of high numbers of senescent cells reduced SKPs’ adipogenic differentiation potential. Treatment with baricitinib, a JAK–STAT inhibitor, ameliorated the ability of HGPS SKPs to differentiate into adipocytes. Our findings suggest that the development of lipodystrophy in patients with HGPS may be associated with an increased rate of cellular senescence and chronic inflammation.

Abstract
As a novel population of neural crest-origin precursor cells, skin-derived precursor cells (SKPs) can be isolated from both embryonic and adult dermis. These cells have important values for research and potential clinical application in wound healing, organ regeneration and disease treatment for advantages in the abundance of cell sources, accessibility, potential of multipotent differentiation, and absence of ethical concerns. Here we review the developmental and anatomical origins of SKPs and their potential application in regenerative medicine. SKPs originate from the embryonic neural crest, and their sources may vary in different areas of the body. SKPs are widely found in the dermis, especially in the dermal papilla (DP), which was known as a niche of SKPs. The multipotent SKPs can used for autologous transplantation and are of vital importance in tissue repair.

Abstract
Nuclei from less differentiated stem cells yield high cloning efficiency. However, pluripotent stem cells are rather difficult to obtain from bovines. Skin-derived precursor (SKPs) cells exhibit a certain degree of pluripotency, which has been shown to enhance the efficiency of nuclear transfer (NT) in pigs. In this study, bovine SKPs were isolated and characterized. Results showed that bovine SKPs expressed nestin, fibronectin, vimentin, pluripotency-related genes, and characteristic neural crest markers, such as NGFR, PAX3, SOX9, SNAI2, and OCT4. Bovine SKPs and fibroblasts were used as NT donor cells to examine and compare the preimplantation developmental potential of reconstructed embryos after somatic cell nuclear transfer (SCNT). Bovine SKP-cloned embryos displayed higher developmental competence in terms of blastocyst formation rate and total cell number in blastocysts compared with the bovine embryonic fibroblast-cloned embryos. This study revealed that bovine SKPs may be considered excellent candidate nuclear donors for SCNT and may provide a promising platform for transgenic cattle generation.
