Summary of "Fasudil enhanced differentiation of BMSCs in vivo and vitro, involvement of P38 signaling pathway."

Bone mesenchymal stem cells (BMSCs) are a well-known donor graft source due to their potential for self-renewal and differentiation into multi-lineage cell types, including osteoblasts that are critical for fracture healing. Fasudil (FAS), a Rho kinase inhibitor, has been proven to induce the differentiation of bone marrow stem cells (BMSCs) into neuron-like cells. However, its role in the osteogenesis of BMSCs remain uncertain. Herein, we for the first time studied the effects of FAS on osteogenic differentiation in a mouse fracture model and further explored the involved mechanisms in mouse BMSCs. The results showed that FAS stimulated bone formation in the fracture mouse model. Additionally, at 30 μM, FAS significantly promotes alkaline phosphatase activity, mineralization, and the expression of osteogenic markers COL-1, RUNX2 and OCN in murine BMSCs. Blocking of P38 by SB202190 significantly reversed the effects of FAS, in vitro, suggesting that P38, but not ERK or JNK activation is required for FAS-induced osteogenesis. Collectively, our results indicate that FAS may be a promising agent for promoting fracture healing.

Medical and Biotech [MESH] Definitions

The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.

Mutagenesis where the mutation is caused by the introduction of foreign DNA sequences into a gene or extragenic sequence. This may occur spontaneously in vivo or be experimentally induced in vivo or in vitro. Proviral DNA insertions into or adjacent to a cellular proto-oncogene can interrupt GENETIC TRANSLATION of the coding sequences or interfere with recognition of regulatory elements and cause unregulated expression of the proto-oncogene resulting in tumor formation.

Cell surface receptors that are specific for INTERLEUKIN-1. Included under this heading are signaling receptors, non-signaling receptors and accessory proteins required for receptor signaling. Signaling from interleukin-1 receptors occurs via interaction with SIGNAL TRANSDUCING ADAPTOR PROTEINS such as MYELOID DIFFERENTIATION FACTOR 88.

A growth differentiation factor that may play a role in maintaining the undifferentiated state of PLURIPOTENT STEM CELLS by inhibiting the actions of BONE MORPHOGENETIC PROTEINS. Differentiation factor 3 is also considered a nodal signaling ligand that influences the genesis of left-right asymmetry.

The extent to which an RNA molecule retains its structural integrity and resists degradation by RNASE, and base-catalyzed HYDROLYSIS, under changing in vivo or in vitro conditions.
