Development and optimization of a dual-photoinitiator, emulsion-based technique for rapid generation of cell-laden hydrogel microspheres.
Emerging medical technologies for effective and lasting repair of articular cartilage include delivery of cells or cell-seeded scaffolds to a defect site to initiate de novo tissue regeneration. Biocompatible scaffolds assist in providing a template for cell distribution and extracellular matrix accumulation in a three-dimensional geometry. In these studies, a self-assembling peptide hydrogel is evaluated as a potential scaffold for cartilage repair using a model bovine cell source. A seeding technique is developed for 3-D encapsulation of chondrocytes in a peptide hydrogel. The chondrocyte-seeded peptide hydrogel was then evaluated cellular activities in vitro under standard culture conditions and also when subjected to dynamic compression. During 4 weeks of culture in vitro, chondrocytes seeded within the peptide hydrogel retained their morphology and developed a cartilage-like ECM rich in proteoglycans and type II collagen, indicative of a stable chondrocyte phenotype. Time dependent ...
Hydrogel particles, also known as microgels, consist of cross-linked three-dimensional water-soluble polymer networks. They play an essential role in loading and delivering active ingredients in medicine, cosmetics, and foods. Despite their excellent biocompatibility as well as structural diversity, much wider applications are limited due mainly to their intrinsically loose network nature. This study introduces a practical and straightforward method that enables fabrication of hydrogel microparticles layered with a mechanically robust hybrid thin shell. Basically highly monodisperse hydrogel microparticles were produced in microcapillary devices. Then, their surface was coated with alternate polyelectrolyte layers through the layer-by-layer deposition. Finally a thin silica layer was again formed by reduction of silicate on the amino-functionalized polyelectrolyte layer. We have figured out that these hybrid hydrogel microparticles showed controlled loading and releasing behaviors for ...

The combination of hydrogel and nitrogen may favor the expression of grain productivity of wheat. The goal of the study was to analyze the nitrogen utilization efficiency in wheat through the hydrogel biopolymer, defining the optimal dose of hydrogel and nitrogen combination at the maximum grain productivity, in succession systems of high and reduced N-residual release. The study was carried out in 2014 and 2015, in randomized block design with four replicates in a 4 x 4 factorial, for hydrogel doses (0, 30, 60 and 120 kg ha-1), added in the furrow along the seed and fertilizer-N doses (0, 30, 60 and 120 kg ha-1), applied in the stage of third leaf expanded, respectively, in the soy/wheat and corn/wheat systems. The hydrogel biopolymer increases the efficiency of nitrogen use in grain productivity of wheat in succession systems. The ideal combination of hydrogel and nitrogen at the maximum grain productivity is 58 and 93 kg ha-1, respectively, in the soybean/wheat systems and 44 and 115 kg ha-1, ...

Group led by Dr. Avinash Bajaj from Regional Centre for Biotechnology designed a low molecular weight hydrogel that can maintain sustained and sequential release of combination of drugs and inhibit the tumor progression in murine models. Using the bioconjugation strategies and biocompatible bile acid and peptide scaffolds, Dr. Bajajs group engineered a biocompatible and biodegradable hydrogel. They then entrapped a combination of anti-proliferative (doxorubicin), anti-angiogenic (combretastatin) and anti-inflammatory (dexamethasone) drugs in the hydrogel. Local implantation of the hydrogel reduces the tumor growth kinetics significantly and enhances the median survival. In collaboration with Dr. Ujjaini Dasgupta group at Amity University, Haryana, they have deciphered the in-depth mechanism and found that hydrogel-mediated delivery of combination of drugs alters the sphingolipid metabolism and helps in combating drug resistance..

Weve all had booster shots at some point in our lives. You know, you get an immunization injection, then at some point in the future you have to have another round to make sure you have the proper level of immunity.. This can be a major pain (pardon the pun) for many of us. When I received my Hepatitis B vaccine while in dental school, the proper protocol was for a 3 shot series.. Now, in dental school, it was easy. The injections were given by the oral surgery department and I was notified when to return for my next round. However, in the real world this can mean more trips to a doctors office for these follow up visits. This can result in lost work time, taking kids out of school, etc. Not to mention the fact that you actually have to get the injections to ensure immunity. Lots of people either forget or are scared and just dont get them.. Now comes word of a way around these booster injections.. The idea is to place a booster amount in a small pea sized hydrogel capsule that is injected ...

Travoprost was encapsulated in various formulations of polylactide microparticles (PM), which were dry blended and suspended in a multi-arm polyethylene glycol (PEG) precursor solution conjugated with fluorescein and injected into small bore tubing prior to cross-linking. The travoprost in the PM/hydrogel matrix was dried in tubing and cut into plugs. Drug release rate from the respective formulations was assessed in PBS at pH 7.4 at 37 C until complete dissolution. The 3-month formulation was evaluated for plug visualization through the tissue in a canine model under illumination with a blue light and yellow filter.. ...
Biomaterial-based regenerative approaches would allow for cost-effective off-the-shelf solution for the treatment of wounds. Hyaluronan (HA)-based hydrogel is one attractive biomaterial candidate because it is involved in natural healing processes, including inflammation, granulation, and reepi-thelialization. Herein, dynamic metal-ligand coordination bonds are used to fabricate moldable supramolecular HA hydrogels with self-healing properties. To achieve reversible crosslinking of HA chains, the biopolymer is modified with pendant bisphosphonate (BP) ligands using carbodiimide coupling and chemoselective "click" reactions. Hydrogel is formed immediately after simple addition of silver (Ag+) ions to the solution of HA containing BP groups (HA-BP). Compared with previous HA-based wound healing hydrogels, the HA-BP·Ag+ hydrogel is highly suitable for clinical use as it can fill irregularly shaped wound defects without the need for premolding. The HA-BP·Ag+ hydrogel shows antimicrobial ...

Objectives: Direct pulp capping is a treatment for preserving the vital pulp. However, a satisfactory material for caries-exposed inflamed pulp in permanent teeth is not currently available. Thus, a biologically-based material that promotes the continued formation of a new dentin-pulp complex is needed. A hydrogel drug delivery vehicle is a promising material, however its cytotoxicity has barely been explored. The aim of this study is to evaluate the cytotoxicity of a hydrogel drug delivery vehicle and its components in a cell culture system in vitro. Methods: The hydrogel solution was prepared by mixing poly(ethylene glycol)maleate-citrate (45% w/v)[PEGMC], acrylic acid (5% w/v)[AA], 2,2-Azobis(2-methylpropionamidine) dihydrochloride photoinitiator (0.1% w/v)[AAPH], and deionized water. Various concentrations of the hydrogel and its components were prepared in the cell culture medium. L929 cells were seeded into 96-well plates at 3x103 cells/well and cultured with each concentration of the ...

Taking medication often comes with side effects which range in severity which may even deter people from seeking treatment. Accordingly, there is a need for improved efficiency in drug delivery which can be achieved with the use of a nanoparticle drug delivery system. In order to manufacture drug delivery hydrogel particles at a nanoscale, the behavior of the system must first be understood fundamentally. This study focused on quantifying the amount of a drug, chosen to be DL-propranolol hydrochloride, that diffuses into a poly(n-isopropylacrylamide) (PNIPAm) hydrogel at equilibrium. Three gels were synthesized and soaked in a solution containing DL-propranolol hydrochloride for 14 days, which was found to be the amount of time needed for the drug to reach equilibrium (complete diffusion). After this time period, the gels were then sliced into disks in order for the drug to be extracted. Using UV-visible spectroscopy, the concentration of drug in each disk was analyzed. This data, along with the ...

Due to our aging population, an increase in proximal femur fractures can be expected, which is associated with impaired activities of daily living and a high risk of mortality. These patients are also at a high risk to suffer a secondary osteoporosis-related fracture on the contralateral hip. In this context, growth factors could open the field for regenerative approaches, as it is known that, i.e., the growth factor BMP-7 (bone morphogenetic protein 7) is a potent stimulator of osteogenesis. Local prophylactic augmentation of the proximal femur with a BMP-7 loaded thermoresponsive hydrogel during index surgery of an osteoporotic fracture could be suitable to reduce the risk of further osteoporosis-associated secondary fractures. The present study therefore aims to test the hypothesis if a BMP-7 augmented hydrogel is an applicable carrier for the augmentation of non-fractured proximal femurs. Furthermore, it needs to be shown that the minimally invasive injection of a hydrogel into the mouse femur is

Glioblastoma (GBM) invasion and migration are key biological behaviors leading to refractoriness to current therapies and infiltration into the non‑tumor brain parenchyma. GBM cell migration is strongly dependent on tumor architecture in vivo, which is absent in traditional two‑dimensional (2D) monolayer culture. The present study applied a three‑dimensional (3D) hydrogel model to rebuild the tumor architecture in vitro. Treatment with NSC23766, a specific inhibitor of Ras‑related C3 botulinum toxin substrate 1 (Rac1), inhibited the mesenchymal invasiveness however triggered the amoeboid motility called mesenchymal‑amoeboid transition (MAT). Notably, NSC23766 stimulated U87 GBM cell migration in the 3D hydrogel. However, this compound inhibited cell motility in 2D monolayer culture without tumor architecture for MAT, suggesting the advantage of 3D hydrogel to investigate tumor cell invasion. Due to the inverse interaction of Rac1 and Ras homolog family member A (RhoA) signaling in the ...
In this paper, inhomogeneous deformation of a temperature-sensitive hydrogel has been studied and analyzed under arbitrary geometric and boundary conditions. We present the governing equations and equilibrium conditions of an isothermal process based on the monophase gel field theory of hydrogel via a variational approach. We have adopted and implemented an explicit form of energy for temperature-sensitive hydrogel in a three-dimensional finite element method (FEM) using a user-supply subroutine in ABAQUS. For verification purpose, a few numerical results obtained by the proposed approach are compared with existing experimental data and analytical solutions. They are all in good agreement. We also provide several examples to show the possible applications of the proposed method to explain various complex phenomena, including the bifurcation, buckling of membrane, buckling of thin film on compliant substrate and the opening and closure of flowers. © 2013 Elsevier Ltd.

Two complementary β-sheet-forming decapeptides have been created that form binary self-repairing hydrogels upon combination of the respective free-flowing peptide solutions at pH 7 and ,0.2 wt %. The component peptides showed little structure separately but formed extended β-sheet fibres upon mixing, which became entangled to produce stiff hydrogels. Microscopy revealed two major structures; thin fibrils with a twisted or helical appearance and with widths comparable to the predicted lengths of the peptides within a β-sheet, and thicker, longer, interwoven fibres that appear to comprise laterally-packed fibrils. A range of gel stiffnesses (G from 0.05 to 100 kPa) could be attained in this system by altering the assembly conditions, stiffnesses that covered the rheological properties desirable for cell culture scaffolds. Doping in a RGD-tagged component peptide at 5 mol % improved 3T3 fibroblast attachment and viability compared to hydrogel fibres without RGD functionalisation ...
As 3D cell-based models continue to grow in popularity it is natural to try and apply existing 2D assays as a way of expanding experimental capabilities, but it is important to remember that large changes in model format can result in new experimental challenges that must first be overcome before useful data can be generated.. A common request that we often get at Visikol is if we can immunolabel microtissues encapsulated or grown in Matrigel; one of the first 3D cell culture options commercially available and a well know protein-based scaffold. Using Matrigel can result in cells expressing exciting biological phenotypes, but it can also introduce some unexpected complications with antibody labels. When immunolabeling tissues and microtissues the challenge is to get even labeling from the primary antibody. When you encapsulate tissues inside a hydrogel you have introduced an additional physical obstacle that the antibodies must first move through before they can begin to diffuse into the tissue. ...
EN] Plasma-liquid electrochemistry was successfully used to synthesize gold nanoparticles in a watery background (AuNPs) and also embedded within a hydrogel network (PVA-AuNPs) without using any capping or reducing agents. Nanoparticles of different sizes and morphologies were obtained and the effect of the precursor concentration on the NPs size was examined. The effect of the hydrogel was also studied and it is though that it is responsible of stabilizing and avoiding the agglomeration of the NPs. This atmospheric-microplasma set-up was then used to create gold and silver mixed nanoparticles (Au-AgNPs) and PVA capped with these bimetallic nanoparticles (PVA-AuAgNPs). Their absorption properties were analysed using ultraviolet-visible (UV-Vis) spectroscopy and their size and shape using transmission electron microscopy (TEM). Antibacterial characteristics of the NPs embedded within the PVA matrix were also tested against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) showing a ...

These are pictures showing the changing shape of the hydrogel as it walks in a water environment in responses to changes of temperature. (Credit: Kim et al. Nature Materials). In research published in Nature Materials, a team led by scientists from the RIKEN Center for Emergent Matter Science in Japan has developed a new hydrogel that works like an artificial muscle-quickly stretching and contracting in response to changing temperature. They have also managed to use the polymer to build an L-shaped object that slowly walks forward as the temperature is repeatedly raised and lowered. Hydrogels are polymers that can maintain large quantities of water within their networks. Because of this, they can swell and shrink in response to changes in the environment such as voltage, heat, and acidity. In this sense they are actually similar to the plant cells, which are able to change shape as the amount of water within them changes in response to environmental conditions.. However, most hydrogels do this ...

Human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CMs) have great potential as tools for human heart disease modeling and drug discovery. However, their contractile properties have not been routinely evaluated; as current methods are not accessible for most laboratories. We sought to develop a more efficient method to evaluate hiPSC-CM mechanical properties, at the single cell level. Individual hiPSC-CMs were cultured on a hydrogel based platform, termed the "hydrogel mattress," and their cellular contractile properties evaluated using video-based edge detection. We found that hiPSC-CMs maintained on the mattress reproducibly exhibited robust cell shortening, in dramatic contrast to hiPSC-CMs maintained in a standard manner. We further found that contraction and peak cell shortening amplitude of hiPSC-CMs on mattress was comparable to that of freshly isolated adult ventricular mouse CM. Importantly, hiPSC-CMs maintained on the mattress exhibited several characteristics of a ...
