Abstract
ABSTRACT There is a growing interest in the study of unspecialized mesenchymal stem cells, for there are still some discussions about their in vitro behavior. Regenerative medicine is a science undergoing improvement which develops treatments as cell therapy using somatic stem cells. In several studies, adipose tissue is presented as a source of multipotent adult cells that has several advantages over other tissue sources. This study aimed to characterize and evaluate the tagging of mesenchymal stem cells from the agoutis adipose tissue (Dasyprocta prymonolopha), with fluorescent intracytoplasmic nanocrystals. Fibroblast cells were observed, plastic adherent, with extended self-renewal, ability to form colonies, multipotency by differentiation into three lineages, population CD90 + and CD45 - expression, which issued high red fluorescence after the tagging with fluorescent nanocrystals by different paths and cryopreserved for future use. It is possible to conclude that mesenchymal stem cells from agouti adipose tissue have biological characteristics and in vitro behavior that demonstrate its potential for use in clinical tests.

Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF superfamily and plays multifunctional roles in the immune system. In the present study, a homolog of TRAIL from the Mongolian horse (named ecTRAIL) was identified and characterized. The 870-bp open reading frame encodes a polypeptide of 289 amino acid residues with a predicted molecular weight of 33.47 kDa and pI of 8.47. The genomic structure of ecTRAIL shares a five-exon/six-intron arrangement similar to its orthologs. Multiple alignments show that ecTRAIL is a type II transmembrane protein with a typical transmembrane region, three conserved cysteine residues (Cys56, Cys77, Cys238) and a TNF family signature sequence ([LV]-x-[LIVM]-x(3)-G-[LIVMF]-Y-[LIVMFY](2)-x(2)-[QEKHL]-[LIVMGT]-x-[LIVMFY]). Three-dimensional structure prediction based on the same template revealed that the positional arrangement of the key amino acid residues, Cys238 and Cys230 in ecTRAIL and human TRAIL, respectively, is significantly conserved. Evolutionary analysis suggests that ecTRAIL is most closely related to its ortholog from pigs, with an identity of 83.99%. The solubilizing small ubiquitin-related modifier (SUMO) tag fused recombinant protein SUMO-ecsTRAIL was successfully expressed in E. coli and exhibited binding activity and cytotoxicity to HeLa cells in a cross-species manner in vitro. These results provide a better understanding of TRAILs in mammals and indicate that ecTRAIL may play an important role in the immune response in horses.

Abstract
Studies on adipogenesis may be important for regulating human and/or animal obesity, which causes several complications such as, type II diabetes, hypertension, and cardiovascular disease, thus giving rise to increased economic burden in many countries. Previous reports revealed that various flavonoids have anti-apoptotic, antioxidant, and cell differentiation-regulating activities with a number of physiological benefits, including protection from cardiovascular disease, cancers, and oxidative stress. As we found that the hydroxylation patterns of the flavonoid B ring are known to play a critical role in their function, we screened several flavonoids containing different numbers and positions of OH substitutions in B ring for their modulatory property on adipogenesis. In this study, we revealed the anti-adipogenic activity of the naturally derived flavonoid, 3,4'-dihydroxyflavone (3,4'-DHF) in murine 3T3-L1 pre-adipocytes and equine adipose-derived stromal cells (eADSCs). We found that treatment with 3,4'-dihydroxyflavone (3,4'-DHF) led to decreased expression of adipogenic markers and lipid deposition with differential modulation of ROS and kinase signaling pathways. Regulation of ROS generation through the differential modulation of ROS-regulating gene expression was revealed to have an important role in the suppression of adipogenesis and increase of osteogenesis in eADSCs following 3,4'-DHF treatment. These results suggest that the flavonoid 3,4'-DHF can be used to regulate adipogenesis in ADSCs, which has potential therapeutic application in regenerative medicine or health care for humans and many sport or companion animals.

Abstract
A proliferation inducing ligand (APRIL) is a member of the TNF superfamily. It shares two receptors with B-cell activating factor (BAFF), B-cell maturation antigen (BCMA), and transmembrane activator and CAML interactor (TACI). Herein, the equine APRIL was identified from equine adipose-derived stem cell (ASC), and the protein expression of APRIL and its related molecules were detected during the adipogenic differentiation of equine ASC in vitro. The equine APRIL gene was located on chromosome 11, spans 1852 base pairs (bp). Its open reading frame covers 753 bp, encoding a 250-amino acid protein with the typical TNF structure domain. During the two weeks' adipogenic differentiation of equine ASC, although the protein expression of APRIL and TACI had an insignificant change, that of BCMA increased significantly. Moreover, with the addition of recombinant protein His6-sAPRIL, a reduced differentiation of equine ASC toward adipocyte was detected. These results may provide the basis for investigating the role of APRIL in ASC adipogenic differentiation.

Abstract
B-cell-activating factor (BAFF) has recently been demonstrated to be expressed in adipocytes and up-regulated by high-fat diet feeding, indicating a possible role in metabolic regulation. Here we show that glucose tolerance was significantly improved in high-fat diet-fed BAFF knockout (BAFF(-/-)) mice. BAFF(-/-) mice revealed higher levels of glucose transporter expression and insulin-stimulated Akt phosphorylation in brown adipose tissue compared to wild type controls. Expression levels of mitochondrial ND5 and genes involved in lipid metabolism were significantly elevated in brown adipose tissue of BAFF(-/-) mice, and this enhancement was found to be mediated by FGF21 and leptin. It was also observed that expression of IL-10 and foxp3 was increased in adipose tissues, as well as PPARγ activity in white adipose tissue. Our findings suggest that suppression of BAFF could have a therapeutic potential for prevention of type 2 diabetes.

Abstract
Mesenchymal stem cells, considered one of the most promising cell types for therapeutic applications due to their capacity to secrete regenerative bioactive molecules, are present in all tissues. Stem cells derived from the adipose tissue have been increasingly used for cell therapy in humans and animals, both as freshly isolated, stromal vascular fraction (SVF) cells, or as cultivated adipose-derived stem cells (ASCs). ASCs have been characterized in different animal species for proliferation, differentiation potential, immunophenotype, gene expression, and potential for tissue engineering. Whereas canine and equine ASCs are well studied, feline cells are still poorly known. Many companies around the world offer ASC therapy for dogs, cats, and horses, although in most countries these activities are not yet controlled by regulatory agencies. This is the first study to review the characterization and clinical use of SVF and ASCs in spontaneously occurring diseases in veterinary patients. Although a relatively large number of studies investigating ASC therapy in induced lesions are available in the literature, a surprisingly small number of reports describe ASC therapy for naturally affected dogs, cats, and horses. A total of seven studies were found with dogs, only two studies in cats, and four in horses. Taken as a whole, the results do not allow a conclusion on the effect of this therapy, due to the generally small number of patients included, diversity of cell populations used, and lack of adequate controls. Further controlled studies are clearly needed to establish the real potential of ASC in veterinary medicine.
