The skin is a natural target of stem cell research because of its large size and easy accessibility. Cutaneous mesenchymal stem cells have shown to be a promising source of various adult stem cell or progenitor cell populations, which provide an important source of stem cell-based investigation. Nowadays, much work has been done on dermal-derived mesenchymal stem cells (DMSCs) from humans, mice, sheep, and other mammals, but the literature on avian species has been rarely reported. As an animal model, the goose is an endemic species abounding in dermal tissues which is important in the global economy...

Fracture healing is a repair process of a mechanical discontinuity loss of force transmission, and pathological mobility of bone. Increasing evidence suggests that microRNA (miRNA) could regulate chondrocyte, osteoblast, and osteoclast differentiation and function, indicating miRNA as key regulators of bone formation, resorption, remodeling, and repair. Hence, during this study, we established a right femur fracture mouse model to explore the effect microRNA-185 (miR-185) has on osteoblasts in mice during fracture healing and its underlying mechanism...

Common protocols for chondrogenic differentiation of adipose-derived mesenchymal stem cells (ADSCs) are generally expensive and time-consuming and so far, have not successfully recreated pure chondrocytes. We hypothesize that a low level of H2 O2 may induce differentiation of ADSCs into chondrocytes in a shorter incubation time and relatively lower cost. Therefore, this study aimed to comparatively investigate the effectiveness of H2 O2 -containing or free medium in the induction of ADSCs to chondrocytes. ADSCs were isolated from the lipoaspirate of four healthy females and evaluated by immunophenotyping for their CD90, CD73, CD44, CD34, and CD45 cell surface markers...

BACKGROUND: Intervertebral disc (IVD) degeneration is characterized by an early decrease in cellularity of the nucleus pulposus (NP) region, and associated extracellular matrix changes, reduced hydration, and progressive degeneration. Cell-based IVD therapy has emerged as an area of great interest, with studies reporting regenerative potential for many cell sources, including autologous or allogeneic chondrocytes, primary IVD cells, and stem cells. Few approaches, however, have clear strategies to promote the NP phenotype, in part due to a limited knowledge of the defined markers and differentiation protocols for this lineage...

Lymphoid tissue organizer (LTo) cells, identified in mouse and human embryos, are thought to be precursors of stromal cells in secondary lymphoid organs. Whether LTo cells are present in human adults, however remains unknown. We obtained 15 stromal cell lines from tonsils from children who underwent tonsillectomy, and studied the antigen phenotype of these tonsil stromal cell (TSC) lines by flow cytometry and RT-PCR. Cell lines met the minimal criteria proposed by the International Society for Cellular Therapy to define human mesenchymal stem/stromal cells (MSCs): plastic-adherent capacity; expression of CD73, CD90 and CD105, lack of CD45, CD19 and HLA-DR; and capacity to differentiate into adipocytes, osteoblasts and chondrocytes...

The proliferative rate of chondrocytes affects bone elongation. Chondrocyte hypertrophy is required for endochondral bone formation as chondrocytes secrete factors required for osteoblast differentiation and maturation. Previous studies have demonstrated that the Indian hedgehog (Ihh) signaling pathway is a key regulator of skeletal development and homeostasis. The aim of the present study was to investigate the function of Ihh in chondrocyte proliferation and differentiation, as well as the underlying mechanisms...
