Menstrual blood CD146 mesenchymal stem cells reduced fibrosis rate in the rat model of premature ovarian failure.

Here, the regenerative potential of menstrual blood-derived mesenchymal stem cells (MenSCs) was examined on restoration of premature ovarian failure (POF) ovaries in rats' POF model. Freshly isolated CD146 MenSCs using magnetic-activated cell storing method were immediately injected into ovaries of POF rats. Four and eight weeks after cell administration, both ovarian tissues were sampled for histological examination and the expression of fibrosis-related genes.

Naturally circulating pertactin-deficient strains induce distinct gene expression and inflammatory signatures in human dendritic cells.

Respiratory infections caused by are reemerging despite high pertussis vaccination coverage. Since the introduction of the acellular pertussis vaccine in the late twentieth century, circulating strains increasingly lack expression of the vaccine component pertactin (Prn). In some countries, up to 90% of the circulating strains are deficient in Prn.

Enhanced Extracellular Matrix Breakdown Characterizes the Early Distraction Phase of Canine Knee Joint Distraction.

Objective: Joint distraction triggers intrinsic cartilage repair in animal models of osteoarthritis (OA), corroborating observations in human OA patients treated with joint distraction. The present study explores the still largely elusive mechanism initiating this repair process.

Design: Unilateral OA was induced in the knee joint of 8 dogs using the groove model; the contralateral joint served as a control.

Intra-ovarian injection of platelet-rich plasma into ovarian tissue promoted rejuvenation in the rat model of premature ovarian insufficiency and restored ovulation rate via angiogenesis modulation.

Premature Ovarian Insufficiency (POI) is viewed as a type of infertility in which the menopausal status occurs before the physiological age. Several therapeutic strategies have been introduced in clinic for POI treatment, although the outputs are not fully convincing. Platelet-rich plasma (PRP) is a unique blood product widely applied in regenerative medicine, which is based on the releasing of the growth factors present in platelets α-granules.

Ovarian function and reproductive outcome after ovarian tissue transplantation: a systematic review.

The aim of this systematic review study is to summarize the current knowledge of ovarian tissue transplantation and provide insight on ovarian function, fertility and reproductive outcome following ovarian tissue transplantation. Relevant studies were identified by searching through PubMed, Cochrane Library, Embase, ProQuest, and Scopus databases until August 2018. Ovarian function by examination of the hormonal level was evaluated, together with follicular growth, the return of menstrual cycle and assessment of reproductive consequences: pregnancy, miscarriage rates and live birth after transplantation.

Effectiveness of Stem Cell Therapy in the Treatment of Ovarian Disorders and Female Infertility: A Systematic Review.

Background: Infertility is a major problem worldwide. Various strategies are being used to develop better treatments for infertility and The most trending strategy is the stem cell therapy. In this study, the literature on stem cell therapy for ovarian disorders is summarized with analysis of current developments.

Dog as a Model for Osteoarthritis: The FGF4 Retrogene Insertion May Matter.

Osteoarthritis (OA) is a degenerative joint disease associated with chronic pain and disability in humans and companion animals. The canine species can be subdivided into non-chondrodystrophic (NCD) and chondrodystrophic (CD) dogs, the latter having disproportionally short limbs due to disturbance in endochondral ossification of long bones. This phenotype is associated with retrogene insertions of the fibroblast growth factor 4 (FGF4) gene, resulting in enhanced fibroblast growth factor receptor 3 (FGFR3) signaling.

Hypoxia negatively affects senescence in osteoclasts and delays osteoclastogenesis.

Cellular senescence, that is, the withdrawal from the cell cycle, combined with the acquirement of the senescence associated secretory phenotype has important roles during health and disease and is essential for tissue remodeling during embryonic development. Osteoclasts are multinucleated cells, responsible for bone resorption, and cell cycle arrest during osteoclastogenesis is well recognized. Therefore, the aim of this study was to investigate whether these cells should be considered senescent and to assess the influence of hypoxia on their potential senescence status.

Biologic canine and human intervertebral disc repair by notochordal cell-derived matrix: from bench towards bedside.

The socioeconomic burden of chronic back pain related to intervertebral disc (IVD) disease is high and current treatments are only symptomatic. Minimally invasive strategies that promote biological IVD repair should address this unmet need. Notochordal cells (NCs) are replaced by chondrocyte-like cells (CLCs) during IVD maturation and degeneration.

Growth plate expression profiling: Large and small breed dogs provide new insights in endochondral bone formation.

The difference in the adult height of mammals, and hence in endochondral bone formation, is not yet fully understood and may serve to identify targets for bone and cartilage regeneration. In line with this hypothesis, the intra-species disparity between the adult height of Great Danes and Miniature Poodles was investigated at a transcriptional level. Microarray analysis of the growth plate of five Great Danes and five Miniature Poodles revealed 2,981 unique genes that were differentially expressed, including many genes with an unknown role in skeletal development.

Bone Morphogenetic Protein-2, But Not Mesenchymal Stromal Cells, Exert Regenerative Effects on Canine and Human Nucleus Pulposus Cells.

Chronic back pain is related to intervertebral disc (IVD) degeneration and dogs are employed as animal models to develop growth factor- and cell-based regenerative treatments. In this respect, the differential effects of transforming growth factor beta-1 (TGF-β) and bone morphogenetic protein-2 (BMP2) on canine and human chondrocyte-like cells (CLCs) derived from the nucleus pulposus of degenerated IVDs were studied. Human and canine CLCs were cultured in 3D microaggregates in basal culture medium supplemented with/without TGF-β (10 ng/mL) or BMP2 (100 or 250 ng/mL).

Increased caveolin-1 in intervertebral disc degeneration facilitates repair.

Background: Preceding intervertebral disc (IVD) degeneration, the cell phenotype in the nucleus pulposus (NP) shifts from notochordal cells (NCs) to chondrocyte-like cells (CLCs). Microarray analysis showed a correlation between caveolin-1 expression and the phenotypic transition of NCs to CLCs. With a clinical directive in mind, the aim of this study was to determine the role of caveolin-1 in IVD degeneration.
