Retinoic acid (RA) is able to induce the differentiation of embryonic stem cells into neuronal lineages. The mechanism of this effect is unknown but it has been evidenced to be dependent on the formation of floating spheroids called embryoid bodies. Results presented here show that the inhibition of phosphoinositide 3-kinase signaling pre-determines mouse embryonic stem cells to RA induced neurogenesis in monolayer culture with no need of embryoid bodies formation. 相似文献

Although previous studies have demonstrated that hydrogen sulfide (H2S) stimulated or inhibited osteoclastic differentiation, little is known about the effects of H2S on the differentiation of osteoblasts and osteoclasts. To determine the possible bioactivities of H2S on bone metabolism, we investigated the in vitro effects of H2S on cytotoxicity, osteoblastic, and osteoclastic differentiation as well as the underlying mechanism in lipopolysaccharide (LPS) and nicotine‐stimulated human periodontal ligament cells (hPDLCs). The H2S donor, NaHS, protected hPDLCs from nicotine and LPS‐induced cytotoxicity and recovered nicotine‐ and LPS‐downregulated osteoblastic differentiation, such as alkaline phosphatase (ALP) activity, mRNA expression of osteoblasts, including ALP, osteopontin (OPN), and osteocalcin (OCN), and mineralized nodule formation. Concomitantly, NaHS inhibited the differentiation of tartrate‐resistant acid phosphatase (TRAP)‐positive osteoclasts in mouse bone marrow cells and blocked nicotine‐ and LPS‐induced osteoclastogenesis regulatory molecules, such as RANKL, OPG, M‐CSF, MMP‐9, TRAP, and cathepsin K mRNA. NaHS blocked nicotine and LPS‐induced activation of p38, ERK, MKP‐1, PI3K, PKC, and PKC isoenzymes, and NF‐κB. The effects of H2S on nicotine‐ and LPS‐induced osteoblastic and osteoclastic differentiation were remarkably reversed by MKP‐1 enzyme inhibitor (vanadate) and expression inhibitor (triptolide). Taken together, we report for the first time that H2S inhibited cytotoxicity and osteoclastic differentiation and recovered osteoblastic differentiation in a nicotine‐ and periodontopathogen‐stimulated hPDLCs model, which has potential therapeutic value for treatment of periodontal and inflammatory bone diseases.

Mesenchymal stem cells (MSCs) are an important cell population in the bone marrow microenvironment. MSCs have the capacity to differentiate in vitro into several mesenchymal tissues including bone, cartilage, fat, tendon, muscle, and marrow stroma. This study was designed to isolate, expand, and characterize the differentiation ability of sheep bone marrow‐derived MSCs and to demonstrate the possibility to permanently express a reporter gene. Bone marrow was collected from the iliac crest and mononuclear cells were separated by density gradient centrifugation. Sheep MSCs cell lines were stable characterized as CD44+ and CD34? and then transfected with a green fluorescent protein (GFP) reporter gene. The GFP expression was maintained in about half (46.6%) of cloned blastocysts produced by nuclear transfer of GFP+ sheep MSCs, suggesting the possibility to establish multipotent embryonic cells' lines carrying the fluorescent tag for comparative studies on the differentiation capacity of adult stem cells (MSCs) versus embryonic stem cells. We found that sheep MSCs under appropriate culture conditions could be induced to differentiate into adipocytes, chondrocytes, and osteoblast lineages. Our results confirm the plasticity of sheep MSCs and establish the foundation for the development of a pre‐clinical sheep model to test the efficiency and safety of cell replacement therapy. J. Cell.

Parkinson's disease (PD) is the second most common neurodegenerative disorder. The motor symptoms of PD are caused by the loss of dopaminergic (DA) neurons in the substantia nigra pars compacta of mesencephalon. The causes for death of DA neurons are not well understood, but the strongest risk factor is increasing age. There is no cure currently available for PD, and treatment is limited to management of PD symptoms in patients. Primary DA neurons are virtually unobtainable from living patients and animal studies have proven inadequate for studying the mechanism of PD development. Pluripotent stem cells (PSC) are primary self‐renewing cells capable of differentiating into all cell types of an organism, including DA neurons. PSCs represent an abundant source of cells that can be genetically modified or isolated from patients with complex diseases, enabling the production of large quantities of DA neurons for disease modeling, drug screening, and gene function studies. Furthermore, since PD arises as a result of deterioration of DA neurons in a specific brain region, it has been suggested that a relatively small number of cells could restore normal function. PSCs could provide a source of DA neurons for cell replacement therapy. In this Prospects article, we focus on the development and in vitro derivation of DA neurons from PSCs, as well as current applications of the technological advances, with the emphasis on future directions and efforts in the field.
