Embryotrophic effect of exogenous protein contained adipose-derived stem cell extracellular vesicles.

Background: Extracellular vesicles (EVs) regulate cell metabolism and various biological processes by delivering specific proteins and nucleic acids to surrounding cells. We aimed to investigate the effects of the cargo contained in EVs derived from adipose-derived stem cells (ASCs) on the porcine embryonic development.

Methods: ASCs were isolated from porcine adipose tissue and characterized using ASC-specific markers via flow cytometry.

Evaluation of porcine intestinal organoids as an model for mammalian orthoreovirus 3 infection.

Background: Mammalian orthoreovirus type 3 (MRV3), which is responsible for gastroenteritis in many mammalian species including pigs, has been isolated from piglets with severe diarrhea. However, the use of pig-derived cells as an infection model for swine-MRV3 has rarely been studied.

Objectives: This study aims to establish porcine intestinal organoids (PIOs) and examine their susceptibility as an model for intestinal MRV3 infection.

Immunomodulatory effects of canine mesenchymal stem cells in an experimental atopic dermatitis model.

Mesenchymal stem cells (MSCs) have the potential to differentiate into multi-lineage cells, suggesting their future applicability in regenerative medicine and biotechnology. The immunomodulatory properties of MSCs make them a promising replacement therapy in various fields of animal research including in canine atopic dermatitis (AD), a skin disease with 10-15% prevalence. We investigated the immunomodulatory effects of MSCs in an experimental canine AD model induced by extract ointment.

Novel method to repair articular cartilage by direct reprograming of prechondrogenic mesenchymal stem cells.

Age-related cartilage loss is worsened by the limited regenerative capacity of chondrocytes. The role of cell-based therapies using mesenchymal stem cells is gaining interest. Adipose tissue-derived mesenchymal stem cells (ADSCs) are an attractive source to generate the optimal number of chondrocytes required to repair a cartilage defect and regenerate hyaline articular cartilage.

Canine Natural Killer Cell-Derived Exosomes Exhibit Antitumor Activity in a Mouse Model of Canine Mammary Tumor.

Natural killer (NK) cells are key immune cells engaged in fighting infection and malignant transformation. In this study, we found that canine NK cell-derived exosomes (NK-exosomes) separated from activated cytotoxic NK cell supernatants express specific markers including CD63, CD81, Alix, HSP70, TSG101, Perforin 1, and Granzyme B. We examined the antitumor effects of NK-exosomes in an experimental murine mammary tumor model using REM134 canine mammary carcinoma cell line.

Bovine tongue epithelium-derived cells: A new source of bovine mesenchymal stem cells.

Mesenchymal stem cells (MSCs) possess the ability to differentiate into multiple cell lineages, and thus, confer great potential for use in regenerative medicine and biotechnology. In the present study, we attempted to isolate and characterize bovine tongue tissue epithelium-derived MSCs (boT-MSCs) and investigate the culture conditions required for long-term culturing of boT-MSCs. boT-MSCs were successfully isolated by the collagenase digestion method and their proliferative capacity was maintained for up to 20 or more passages.

Effects of three-dimensional spheroid culture on equine mesenchymal stem cell plasticity.

Mesenchymal stem cells (MSCs) are useful candidates for tissue engineering and cell therapy fields. We optimize culture conditions of equine adipose tissue-derived MSCs (eAD-MSCs) for treatment of horse fractures. To investigate enhancing properties of three-dimensional (3D) culture system in eAD-MSCs, we performed various sized spheroid formation and determined changes in gene expression levels to obtain different sized spheroid for cell therapy.

Extensive characterization of feline intra-abdominal adipose-derived mesenchymal stem cells.

Mesenchymal stem cells (MSCs) isolated from various tissues have been well characterized for therapeutic application to clinical diseases. However, in contrast to MSCs from other animal species, the characteristics of feline MSCs have not been fully documented. In this study, we conducted extensive characterization of feline adipose tissue-derived MSCs (fAD-MSCs).

Effect of donor age on the proliferation and multipotency of canine adipose-derived mesenchymal stem cells.

Research into adipose tissue-derived mesenchymal stem cells (AD-MSCs) has demonstrated the feasibility of their use in clinical applications due to their ease of isolation and abundance in adipose tissue. We isolated AD-MSCs from young and old dogs, and the cells were subjected to sequential sub-passaging from passage 1 (P1) to P7. Canine AD-MSCs (cAD-MSCs) were examined for proliferation kinetics, expression of molecules associated with self-renewal, expression of cell surface markers, and differentiation potentials at P3.

Chondrogenic potential and anti-senescence effect of hypoxia on canine adipose mesenchymal stem cells.

Mesenchymal stem cells (MSCs) have the ability to differentiate into multi-lineage cells, which confers great promise for use in regenerative medicine. In this study, canine adipose MSCs (cAD-MSCs) were isolated from canine adipose tissue. These cells clearly represented stemness (Oct4, Sox2, and Nanog) and differentiation potential into the mesoderm (adipocytes, chondrocytes, and osteoblasts) at early passages.

Comparative studies on proliferation, molecular markers and differentiation potential of mesenchymal stem cells from various tissues (adipose, bone marrow, ear skin, abdominal skin, and lung) and maintenance of multipotency during serial passages in miniature pig.

Mesenchymal stem cells (MSCs) have the ability to differentiate into multi-lineage cells, which confers great promise for use in regenerative medicine. In this study, MSCs were isolated from adipose tissue, bone marrow, ear skin, lung, and abdominal skin of miniature pigs (mpMSCs), and the optimal medium (DMEM/F12-Glutamax) was selected for the culturing of mpMSCs. As a result, proliferation of the mpMSCs derived from all tissues was steadily increased when cultured with DMEM/F12-Glutamax during 14 consecutive passages.

Gene cloning and enzymatic properties of hyperthermostable beta-glycosidase from Thermus thermophilus HJ6.

A microorganism (strain HJ6) producing extracellular beta-glycosidase was isolated from a hot springs located in Arima-cho, Hyogo, Japan. The cells were long-rods (2-4 microm) about 0.4 microm in diameter, and formed yellow-colored colonies, like most other strains of the genus Thermus.
