Dual-delivery of VEGF and PDGF by double-layered electrospun membranes for blood vessel regeneration.
Abstract Tissue engineering of small-diameter blood vessels is still challenging because of restenosis and burst. To prevent thrombosis, rapid endothelialization along the lumen of grafts is intended, followed by proliferation of vascular smooth muscle cells (VSMCs) around the exterior for compliance. To this goal, two modified coaxial electrospinning techniques were developed to encapsulate vascular endothelial growth factor (VEGF) and platelet-derived growth factor-bb (PDGF), respectively, to regulate proliferation of vascular endothelial cells (VECs) and VSMCs. Release profiles, in vitro cell proliferation and ...

Channel density and porosity of degradable bridging scaffolds on axon growth after spinal injury.
Abstract Bridges implanted into the injured spinal cord function to stabilize the injury, while also supporting and directing axon growth. The architecture of the bridge is critical to its function, with pores to support cell infiltration that integrates the implant with the host and channels to direct axon elongation. Here, we developed a sucrose fiber template to create poly(lactide-co-glycolide) multiple channel bridges for implantation into a lateral hemisection that had a 3-fold increase in channel number relative to previous bridges and an overall porosity ranging from approximately 70%-90%. Following implant...

Protein-resistant, reductively dissociable polyplexes for in vivo systemic delivery and tumor-targeting of siRNA.
Abstract Small interfering RNA (siRNA) has been considered as a very attractive therapeutic alternative to chemical drugs; however, the chemical and biological instability and poor delivery efficiency of siRNA limit its success in clinical applications. Here we report a protein-resistant, reductively dissociable siRNA delivery system based on self-assembled polyelectrolyte complexes of dextran-siRNA conjugates linked by disulfide bonds. The prepared polyplexes exhibit excellent dispersion stability in the presence of serum because of the anti-fouling property of dextran exposed onto the complex surface. The enzymat...

Cationic microRNA-delivering nanovectors with bifunctional peptides for efficient treatment of PANC-1 xenograft model.
Abstract Therapeutic strategies based on modulation of microRNA activity possess much promise in cancer therapy, but the in vivo delivery of microRNA to target sites and its penetration into tumor tissues remain great challenge. In this work, miR-34a-delivering therapeutic nanocomplexes with a tumor-targeting and -penetrating bifunctional CC9 peptide were proposed for efficient treatment of pancreatic cancers. In vitro study indicated that the nanoparticle-based miR-34a delivery systems could effectively facilitate cellular uptake and greatly up-regulate the mRNA level of miR-34a in PANC-1 cell lines. The up-regu...

The modulation of the oxidative stress response in chondrocytes by Wip1 and its effect on senescence and dedifferentiation during in vitro expansion.
Abstract Obtaining a sufficient number of cells ex vivo for tissue regeneration, which are appropriate for cartilage repair, requires improved techniques for the continuous expansion of chondrocytes in a manner that does not change their innate characteristics. Rapid senescence or dedifferentiation during in vitro expansion results in loss of chondrocyte phenotype and the formation of fibrous cartilage replacement tissue, rather than hyaluronic cartilage, after transplantation. As demonstrated in the current study, wild-type p53-inducible phosphatase (Wip1), a well-established stress modulator, was highly express...

A genomics approach in determining nanotopographical effects on MSC phenotype.
In this report we move these studies into human skeletal or mesenchymal stem cells and propose that direct (mechanical) signalling is important in the early stages of tuning stem cell fate to nanotopography. Using fluorescence in situ hybridization (FISH) and Affymetrix arrays we have evidence that nanotopography stimulates changes in nuclear organisation that can be linked to spatially regulated genes expression with a particular focus on phenotypical genes. For example, chromosome 1 was seen to display the largest numbers of gene deregulations and also a concomitant change in nuclear positioning in response to nanotopogr...

Antigen-coated poly α-hydroxy acid based microparticles for heterologous prime-boost adenovirus based vaccinations.
Abstract Adenoviruses show promising potential as vectors for cancer vaccines, however, their high immunogenicity can be problematic when it comes to homologous prime-boost strategies. In the studies presented here we show that heterologous prime-boost vaccinations involving ovalbumin (OVA)-antigen-coated microparticles as a prime, and adenovirus encoding OVA (AdOVA) as a boost, were equally as effective as homologous AdOVA prime-boosts at generating OVA-specific CD8(+) T-cell responses, which translated into effective tumor protection. OVA-coated biodegradable poly α-hydroxy acid-based microparticles of varying c...

The support of bone marrow stromal cell differentiation by airbrushed nanofiber scaffolds.
Abstract Nanofiber scaffolds are effective for tissue engineering since they emulate the fibrous nanostructure of native extracellular matrix (ECM). Although electrospinning has been the most common approach for fabricating nanofiber scaffolds, airbrushing approaches have also been advanced for making nanofibers. For airbrushing, compressed gas is used to blow polymer solution through a small nozzle which shears the polymer solution into fibers. Our goals were 1) to assess the versatility of airbrushing, 2) to compare the properties of airbrushed and electrospun nanofiber scaffolds and 3) to test the ability of air...

Gold-nanobeacons for simultaneous gene specific silencing and intracellular tracking of the silencing events.
Abstract The potential of a single molecular nanoconjugate to intersect all RNA pathways: from gene specific downregulation to silencing the silencers, i.e. siRNA and miRNA pathways, is demonstrated. Gold-nanobeacons are capable of efficiently silencing single gene expression, exogenous siRNA and endogenous miRNAs while yielding a quantifiable fluorescence signal directly proportional to the level of silencing. The silencing potential is comparable to that of traditional siRNA but the same nanoconjugates structure is also capable of reversing the effect of an exogenous siRNA. We further demonstrate the Gold-nanobea...

Engineering nanocages with polyglutamate domains for coupling to hydroxyapatite biomaterials and allograft bone.
Abstract Hydroxyapatite (HA) is the principal constituent of bone mineral, and synthetic HA is widely used as a biomaterial for bone repair. Previous work has shown that polyglutamate domains bind selectively to HA and that these domains can be utilized to couple bioactive peptides onto many different HA-containing materials. In the current study we have adapted this technology to engineer polyglutamate domains into cargo-loaded nanocage structures derived from the P22 bacteriophage. P22 nanocages have demonstrated significant potential as a drug delivery system due to their stability, large capacity for loading wi...

The effect of adipose tissue derived MSCs delivered by a chemically defined carrier on full-thickness cutaneous wound healing.
Abstract Mesenchymal stem cells (MSCs) have properties which make them promising for the treatment of chronic non-healing wounds. A major so far unmet challenge is the efficient, safe and painless delivery of MSCs to skin wounds. Recently, a surface carrier of medical-grade silicone coated by plasma polymerisation with a thin layer of acrylic acid (ppAAc) was developed, and shown to successfully deliver MSCs to deepithelialised human dermis in vitro. Here we studied the potential of the ppAAc carrier to deliver human adipose tissue derived MSCs (AT-MSCs) to murine full-thickness excisional skin wounds in vivo. Fu...

A chitosan thermogel for delivery of ropivacaine in regional musculoskeletal anesthesia.
Abstract Postoperative pain within the first days following musculoskeletal surgeries is a significant problem for which appropriate management correlates to positive clinical outcomes. While a variety of pain management modalities are currently used for postoperative pain, an optimal strategy has yet to be identified. Utilizing local anesthetics to convey analgesia through neural blockade represents a promising approach to alleviate postoperative pain. Unfortunately, local anesthetics are often associated with short half-lives, local tissue site reactions, and systemic toxicity. Drug delivery systems such as lipos...

Transcatheter based electromechanical mapping guided intramyocardial transplantation and in vivo tracking of human stem cell based three dimensional microtissues in the porcine heart.
Abstract Stem cells have been repeatedly suggested for cardiac regeneration after myocardial infarction (MI). However, the low retention rate of single cell suspensions limits the efficacy of current therapy concepts so far. Taking advantage of three dimensional (3D) cellular self-assembly prior to transplantation may be beneficial to overcome these limitations. In this pilot study we investigate the principal feasibility of intramyocardial delivery of in-vitro generated stem cell-based 3D microtissues (3D-MTs) in a porcine model. 3D-MTs were generated from iron-oxide (MPIO) labeled human adipose-tissue derived mes...

The use of agarose microwells for scalable embryoid body formation and cardiac differentiation of human and murine pluripotent stem cells.
Abstract In most pluripotent stem cell differentiation protocols the formation of embryoid bodies (EBs) is an important step. Here we describe a rapid, straightforward soft lithography approach for the preparation of hydrophilic silicon masters from different templates and the subsequent production of patterned agarose-DMEM microwell surfaces for scalable well standardized stem cell aggregation and EB formation. The non-adhesive agarose microwell plates represent an accurate replication of the templates' topography and were used for aggregation of murine induced pluripotent stem cells (iPSCs) and human embryonic st...

A mechanistic investigation of the effect of keratin-based hemostatic agents on coagulation.
Abstract Uncontrolled bleeding continues to be one of the leading causes of death in individuals following traumatic injury. Prognosis is worsened with the onset of acute coagulopathy characterized by metabolic acidosis, hypothermia and hemodilution, which consequently perpetuates blood loss and increases mortality. While there are several limitations to biomaterials employed as hemostatic agents, keratin biomaterials have demonstrated efficacy in mitigating blood loss in an animal model of hemorrhage in prior studies. Here we investigate the hypothesis that keratins actively participate in coagulation and that a p...

Sulfobetaine as a zwitterionic mediator for 3D hydroxyapatite mineralization.
We report the use of cytocompatible zwitterionic sulfobetaine ligands to enable 3-dimensional in vitro mineralization of HA across covalently crosslinked hydrogels. The overall charge-neutral zwitterionic hydrogel effectively recruited oppositely charged precursor ions while overcame excessive swelling exhibited by anionic and cationic hydrogels under physiological conditions, resulting in denser and structurally well-integrated mineralized composites. Further controls over the size, content, and spatial distribution of the mineral domains within the zwitterionic hydrogel are accomplished by facile adjustments of hydrogel...
