Self‐Assembled Nanoclay Gel With Spheroid MSC‐Derived Exosome Mimetics to Integrate Demineralized Bone Matrix and Noggin‐Targeting miRNA for Synergistic Osteogenesis

Advanced Functional Materials, EarlyView.
We report a versatile nanoclay gel carrier platform that enhances the osteogenic efficacy of demineralized bone matrix (DBM) by integrating nanoclay‐based self‐assembly with cell‐derived exosome mimetics loaded with noggin‐targeting miR‐200c. This design amplifies BMP signaling, thereby promoting DBM‐mediated osteogenesis and offering a promising ...

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

Advanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

Advanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

Lysosome‐Acidifying Nanoparticles Rescue A30P α‐Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease

Advanced Healthcare Materials, EarlyView.
Lysosome‐targeted acidic nanoparticles based on a biodegradable poly(ethylene tetrafluorosuccinate‐co‐succinate) copolymer are engineered to restore impaired lysosomal acidification through pH‐responsive intracellular degradation. Localized acid release enhances autophagic proteolysis, reduces α‐synuclein accumulation, and preserves dopaminergic neuron

Transient Gene Expression by Nonintegrating Lentiviral Vectors

Molecular Therapy, 2006
Nonintegrating lentiviral (NIL) vectors were produced from HIV-1-based lentiviral vectors by introducing combinations of mutations made to disable the integrase protein itself and to alter the integrase recognition sequences (att) in the viral LTR. NIL vectors with these novel combinations of mutations were used to transduce the human T lymphoid cell ...

Transient gene expression in untransformed lymphocytes

European Journal of Immunology, 1987
AbstractConditions for transfection of normal, freshly isolated and mitogen‐stimulated spleen cells were established. A sharp optimum of plasmid at 10 μg per 1.5 × 107 transfected spleen cells per transfection was observed. The Ig promoter and the IgH enhancer activity was found to be restricted to cells of the B lineage also in normal, freshly ...

Transient Gene Expression Levels from Multigene Expression Vectors

Biotechnology Progress, 2007
AbstractMultigene expression vectors are commonly utilized whereby the (over)expression of two or more genes is desired simultaneously and often at supposedly equivalent levels. We have characterized dual‐gene and pEE14.4 RlucMFluc expression plasmids in which the second hCMV‐MIE promoter is replaced with a c‐myc IRES to enable one‐step coordinated ...

Transient gene expression in electroporated Solanum protoplasts

Plant Molecular Biology, 1989
Electroporation was used to evaluate parameters important in transient gene expression in potato protoplasts. The protoplasts were from leaves of wild potato Solanum brevidens, and from leaves, tubers and suspension cells of cultivated Solanum tuberosum cv. Désirée. Reporter enzyme activity, chloramphenicol acetyl transferase (CAT) under the control of
