Abstract
Due to the inherent low immunogenicity and immunosuppressive tumor microenvironment (TME) of malignant cancers, the clinical efficacy and application of tumor immunotherapy have been limited. Herein, a bimetallic drug-gene co-loading network (Cu/ZIF-8@U-104@siNFS1-HA) is developed that increased the intracellular labile iron pool (LIP) and enhanced the weakly acidic TME by co-suppressing the dual enzymatic activities of carbonic anhydrase IX (CA IX) and cysteine desulfurylase (NFS1), inducing a safe and efficient initial tumor immunogenic ferroptosis. During this process, Cu2+ is responsively released to deplete glutathione (GSH) and reduce the enzyme activity of glutathione peroxidase 4 (GPX4), achieving the co-inhibition of the three enzymes and further inducing lipid peroxidation (LPO). Additionally, the reactive oxygen species (ROS) storm in target cells promoted the generation of large numbers of double-stranded DNA breaks. The presence of Zn2+ substantially increased the expression of cGAS/STING, which cooperated with ferroptosis to strengthen the immunogenic cell death (ICD) response and remodel the immunosuppressive TME. In brief, Cu/ZIF-8@U-104@siNFS1-HA linked ferroptosis with immunotherapy through multiple pathways, including the increase in LIP, regulation of pH, depletion of GSH/GPX4, and activation of STING, effectively inhibiting cancer growth and metastasis.

Abstract
The zeta potential of nanoparticles impacts their distribution and metabolism in the body as well as their interaction with medications of varying charges, hence altering therapeutic efficacy and safety. In this paper, the external charges of liposomes were regulated by utilizing a simple and economical method based on competition for protons of cationic chitosan (CS) and anion hyaluronic acid (HA). The charge regulation of a liposomal membrane is generally accomplished by adjusting the ratio of charged lipids within a liposome (e.g., cationic DOTAP or anionic DOPS), the stability of which was maintained by the coating materials of cationic chitosan (CS) or anion hyaluronic acid (HA). A series of nanoparticles could respond to pH-stimulation with adjustable surface charge. Moreover, the sizes of liposomes coated with CS and HA remain within a narrow range. In vitro cytotoxicity tests revealed that the nanocarriers were safe, and the nanoparticles containing antitumor medicines were efficient in tumor therapy. Considering liposomes with different external surface charges could be aimed at diverse therapy purposes. The strategies for regulating liposomal surface charges with high encapsulation rates and certain release cycles reported here could provide a versatile platform as carriers for the delivery of drugs and other macromolecules into human bodies.

Abstract
Aim: To codeliver an anticancer drug (doxorubicin) and siRNA in the form of nanoparticles into CD44-overexpressing colon cancer cells (HT-29) using an anionic, amphiphilic biopolymer comprising modified hyaluronic acid (6-O-[3-hexadecyloxy-2-hydroxypropyl]-hyaluronic acid). Materials & methods: Characterization of nanoparticles was performed using dynamic light scattering, scanning electron microscopy, transmission electron microscopy, molecular docking, in vitro drug release and gel mobility assays. Detailed in vitro experiments, including a gene silencing study and western blot, were also performed. Results: A 69% knockdown of the target gene was observed, and western blot showed 5.7-fold downregulation of the target protein. The repulsive forces between siRNA and 6-O-(3-hexadecyloxy-2-hydroxypropyl)-hyaluronic acid were overcome by hydrogen bonding and hydrophobic interactions. Conclusion: The authors successfully codelivered a drug and siRNA by anionic vector.

Abstract
Nanoparticles (NPs)-based on various ionic polysaccharides, including chitosan, hyaluronic acid, and alginate have been frequently summarized for controlled release applications, however, most of the published reviews, to our knowledge, focused on the delivery of a single therapeutic agent. A comprehensive summarization of the co-delivery of multiple therapeutic agents by the ionic polysaccharides-based NPs, especially on the optimization of the polysaccharide structure for overcoming various extracellular and intracellular barriers toward maximized synergistic effects, to our knowledge, has been rarely explored so far. For this purpose, the strategies used for overcoming various extracellular and intracellular barriers in vivo were introduced first to provide guidance for the rational design of ionic polysaccharides-based NPs with desired features, including long-term circulation, enhanced cellular internalization, controllable drug/gene release, endosomal escape and improved nucleus localization. Next, four preparation strategies were summarized including three physical methods of polyelectrolyte complexation, ionic crosslinking, and self-assembly and a chemical conjugation approach. The challenges and future trends of this rapidly developing field were finally discussed in the concluding remarks. The important guidelines on the rational design of ionic polysaccharides-based NPs for maximized synergistic efficiency drawn in this review will promote the future generation and clinical translation of polysaccharides-based NPs for cancer therapy.

Abstract
Non-viral vectors represent versatile and immunologically safer alternatives for nucleic acid delivery. Nanoneedles and high-aspect ratio nanostructures are unconventional but interesting delivery systems, in which delivery is mediated by surface interactions. Herein, nanoneedles are synergistically combined with polysaccharide-polyplex nanofilms and enhanced transfection efficiency is observed, compared to polyplexes in suspension. Different polyplex-polyelectrolyte nanofilm combinations are assessed and it is found that transfection efficiency is enhanced when using polysaccharide-based polyanions, rather than being only specific for hyaluronic acid, as suggested in earlier studies. Moreover, results show that enhanced transfection is not mediated by interactions with the CD44 receptor, previously hypothesized as a major mechanism mediating enhancement via hyaluronate. In cardiac tissue, nanoneedles are shown to increase the transfection efficiency of nanofilms compared to flat substrates; while in vitro, high transfection efficiencies are observed in nanostructures where cells present large interfacing areas with the substrate. The results of this study demonstrate that surface-mediated transfection using this system is efficient and safe, requiring amounts of nucleic acid with an order of magnitude lower than standard culture transfection. These findings expand the spectrum of possible polyelectrolyte combinations that can be used for the development of suitable non-viral vectors for exploration in further clinical trials.

Abstract
Systemic immunosuppression mediated by tumor-derived exosomes is an important cause for the resistance of immune checkpoint blockade (ICB) therapy. Herein, self-adaptive platelet (PLT) pharmacytes are engineered to mediate cascaded delivery of exosome-inhibiting siRNA and anti-PD-L1 (aPDL1) toward synergized antitumor immunity. In the pharmacytes, polycationic nanocomplexes (NCs) assembled from Rab27 siRNA (siRab) and a membrane-penetrating polypeptide are encapsulated inside the open canalicular system of PLTs, and cytotoxic T lymphocytes (CTLs)-responsive aPDL1 nanogels (NGs) are covalently backpacked on the PLT surface. Upon systemic administration, the pharmacytes enable prolonged blood circulation and active accumulation to tumors, wherein PLTs are activated to liberate siRab NCs, which efficiently transfect tumor cells, silence Rab27a, and inhibit exosome secretion. The immunosuppression is thus relieved, leading to the activation, proliferation, and tumoral infiltration of cytotoxic T cells, which trigger latent aPDL1 release. As such, the competitive aPDL1 exhaustion by PD-L1-expressing exosomes is minimized to sensitize ICB. Synergistically, siRab and aPDL1 induce strong antitumor immunological response and memory against syngeneic murine melanoma. This study reports a bioinspired mechanism to resolve the blood circulation/cell internalization contradiction of polycationic siRNA delivery systems, and renders an enlightened approach for the spatiotemporal enhancement of antitumor immunity.

Interpenetrating gallol functionalized tissue adhesive hyaluronic acid hydrogel polarizes macrophages to an immunosuppressive phenotype. Acta Biomater 2022; 142:36-48. [PMID: 35085799 DOI: 10.1016/j.actbio.2022.01.048] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 01/19/2022] [Accepted: 01/20/2022] [Indexed: 12/20/2022]
Abstract
Innovative scaffold designs that modulate the local inflammatory microenvironment through favorable macrophage polarization and suppressing oxidative stress are needed for successful clinical translation of regenerative cell therapies and graft integration. We herein report derivation of a hydrazone-crosslinked gallol functionalized hyaluronic acid (HA-GA)-based hydrogel that displayed outstanding viscoelastic properties and immunomodulatory characteristics. Grafting of 6% gallol (GA) to a HA-backbone formed an interpenetrative network by promoting an additional crosslink between the gallol groups in addition to hydrazone crosslinking. This significantly enhanced the mechanical stability and displayed shear-thinning/self-healing characteristics, facilitated tissue adhesive properties to porcine tissue and also displayed radical scavenging properties, protecting encapsulated fibroblasts from peroxide challenge. The THP-1 human macrophage cell line or primary bone-marrow-derived murine macrophages cultured within HA-GA gels displayed selective polarization to a predominantly anti-inflammatory phenotype by upregulating IL4ra, IL-10, TGF-β, and TGF-βR1 expression when compared with HA-HA gels. Conversely, culturing of pro-inflammatory activated primary murine macrophages in HA-GA gels resulted in a significant reduction of pro-inflammatory TNF-α, IL-1β, SOCS3 and IL-6 marker expression, and upregulated expression of anti-inflammatory cytokines including TGF-β. Finally, when the gels were implanted subcutaneously into healthy mice, we observed infiltration of pro-inflammatory myeloid cells in HA-HA gels, while immunosuppressive phenotypes were observed within the HA-GA gels. Taken together these data suggest that HA-GA gels are an ideal injectable scaffold for viable immunotherapeutic interventions. STATEMENT OF SIGNIFICANCE: Host immune response against the implanted scaffolds that are designed to deliver stem cells or therapeutic proteins in vivo significantly limits the functional outcome. For this reason, we have designed immunomodulatory injectable scaffolds that can favorably polarize the recruited macrophages and impart antioxidant properties to suppress oxidative stress. Specifically, we have tailored a hyaluronic acid-based extracellular matrix mimetic injectable scaffold that is grafted with immunomodulatory gallol moiety. Gallol functionalization of hydrogel not only enhanced the mechanical properties of the scaffold by forming an interpenetrating network but also induced antioxidant properties, tissue adhesive properties, and polarized primary murine macrophages to immunosuppressive phenotype. We believe such immunoresponsive implants will pave the way for developing the next-generation of biomaterials for regenerative medicine applications.

Abstract
Photoresponsive supramolecular hydrogels based on the host-guest interaction between cyclodextrin (CD) and azobenzene (Azo) are highly favored in "on-demand" biological applications. Nevertheless, most Azo/CD-based hydrogels are UV-responsive, exhibiting poor tissue penetrability and potential cytotoxicity; more importantly, the complete gel-sol transition under irradiation makes intelligent systems unstable. Here, we report a red-light-responsive semiconvertible hydrogel based on tetra-ortho-methoxy-substituted Azo (mAzo)- and CD-functionalized hyaluronic acid (HA). By integrating red-shifted-photoisomerized mAzo with HA, a biocompatible 625 nm-light-responsive polymeric guest with strengthened hydrogen bonding and weakened photoisomerization was synthesized. Upon alternating irradiation, mAzo-HA/CD-HA hydrogels obtained here exhibited reversible mechanical and structural dynamics, while avoiding complete gel-sol transition. This improved semiconvertibility remedies the lack of macroscopic resilience for dynamic system so as to endow supramolecular hydrogels with spatial-temporal mechanics, self-healing, and adhesion. Together with excellent cytocompatibility and manufacturability, these hydrogels show potential advantages in tissue engineering, especially for the regeneration of functional multi-tissue complex.

Abstract
RNA-based therapy is a promising and potential strategy for disease treatment by introducing exogenous nucleic acids such as messenger RNA (mRNA), small interfering RNA (siRNA), microRNA (miRNA) or antisense oligonucleotides (ASO) to modulate gene expression in specific cells. It is exciting that mRNA encoding the spike protein of COVID-19 (coronavirus disease 2019) delivered by lipid nanoparticles (LNPs) exhibits the efficient protection of lungs infection against the virus. In this review, we introduce the biological barriers to RNA delivery in vivo and discuss recent advances in non-viral delivery systems, such as lipid-based nanoparticles, polymeric nanoparticles, N-acetylgalactosamine (GalNAc)-siRNA conjugate, and biomimetic nanovectors, which can protect RNAs against degradation by ribonucleases, accumulate in specific tissue, facilitate cell internalization, and allow for the controlled release of the encapsulated therapeutics.

Abstract
Nucleic acids represent a promising lead for engineering the immune system. However, naked DNA, mRNA, siRNA, and other nucleic acids are prone to enzymatic degradation and face challenges crossing the cell membrane. Therefore, increasing research has been recently focused on developing novel delivery systems that are able to overcome these drawbacks. Particular attention has been drawn to designing lipid and polymer-based nanoparticles that protect nucleic acids and ensure their targeted delivery, controlled release, and enhanced cellular uptake. In this respect, this review aims to present the recent advances in the field, highlighting the possibility of using these nanosystems for therapeutic and prophylactic purposes towards combatting a broad range of infectious, chronic, and genetic disorders.

Abstract
There is an unmet need to develop strategies that allow site-specific delivery of short interfering RNA (siRNA) without any associated toxicity. To address this challenge, we have developed a novel siRNA delivery platform using chemically modified pluronic F108 as an amphiphilic polymer with a releasable bioactive disulfide functionality. The micelles exhibited thermoresponsive properties and showed a hydrodynamic size of ∼291 nm in DLS and ∼200-250 nm in SEM at 37 °C. The grafting of free disulfide pyridyl groups enhanced the transfection efficiency and was successfully demonstrated in human colon carcinoma (HCT116; 88%) and glioma cell lines (U87; 90%), non-cancerous human dermal fibroblast (HDF; 90%) cells as well as in mouse embryonic stem (mES; 54%) cells. To demonstrate the versatility of our modular nanocarrier design, we conjugated the MDGI receptor targeting COOP peptide on the particle surface that allowed the targeted delivery of the cargo molecules to human patent-derived primary BT-13 gliospheres. Transfection experiments with this design resulted in ∼65% silencing of STAT3 mRNA in BT-13 gliospheres, while only ∼20% of gene silencing was observed in the absence of the peptide. We believe that our delivery method solves current problems related to the targeted delivery of RNAi drugs for potential in vivo applications.

Abstract
![]()
Mesenchymal stem/stromal
cells (MSCs) evoke great excitement for
treating different human diseases due to their ability to home inflamed
tissues, suppress inflammation, and promote tissue regeneration. Despite
great promises, clinical trial results are disappointing as allotransplantation
of MSCs trigger thrombotic activity and are damaged by the complement
system, compromising their survival and function. To overcome this,
a new strategy is presented by the silencing of tissue factor (TF),
a transmembrane protein that mediates procoagulant activity. Novel Pluronic-based micelles are designed
with the pendant pyridyl disulfide group, which are used to conjugate
TF-targeting siRNA by the thiol-exchange reaction. This nanocarrier
design effectively delivered the payload to MSCs resulting in ∼72%
TF knockdown (KD) without significant cytotoxicity. Hematological
evaluation of MSCs and TF-KD MSCs in an ex vivo human whole blood
model revealed a significant reduction in an instant-blood-mediated-inflammatory
reaction as evidenced by reduced platelet aggregation (93% of free
platelets in the TF-KD group, compared to 22% in untreated bone marrow-derived
MSCs) and thrombin–antithrombin complex formation. Effective
TF silencing induced higher MSC differentiation in osteogenic and
adipogenic media and showed stronger paracrine suppression of proinflammatory
cytokines in macrophages and higher stimulation in the presence of
endotoxins. Thus, TF silencing can produce functional cells with higher
fidelity, efficacy, and functions.

Abstract
RNA interference (RNAi), a gene regulatory process mediated by small interfering RNAs (siRNAs), has made remarkable progress as a potential therapeutic agent against various diseases. However, RNAi is associated with fundamental challenges such as poor systemic delivery and susceptibility to the nucleases. Targeting ligand-bound delivery vehicles has improved the accumulation of drug at the target site, which has resulted in high transfection efficiency and enhanced gene silencing. Recently, folate receptor (FR)-mediated targeted delivery of siRNAs has garnered attention due to their enhanced cellular uptake and high transfection efficiency toward tumor cells. Folic acid (FA), due to its small size, low immunogenicity, high in vivo stability, and high binding affinity toward FRs, has attracted much attention for targeted siRNA delivery. FRs are overexpressed in a large number of tumors, including ovarian, breast, kidney, and lung cancer cells. In this review, we discuss recent advances in FA-mediated siRNA delivery to treat cancers and inflammatory diseases. This review summarizes various FA-conjugated nanoparticle systems reported so far in the literature, including liposome, silica, metal, graphene, dendrimers, chitosan, organic copolymers, and RNA nanoparticles. This review will help in the design and development of potential delivery vehicles for siRNA drug targeting to tumor cells using an FR-mediated approach.

Abstract
BACKGROUND Using natural polysaccharides from Traditional Chinese Medicine as nanodrug delivery systems have considerable potential for tumor diagnostics and therapeutics. PURPOSE On the basis of targeted therapy and combining the advantages of natural polysaccharides (angelica polysaccharide, APS) and natural Chinese medicine (curcumin, Cur) to design functionalized nanoparticles to improve the therapeutic through cell membrane encapsulation and immunotherapy. STUDY DESIGN AND METHODS Cur-loaded, glycyrrhetic acid (GA)-APS-disulfide bond (DTA)-Cur nanomicelle (GACS-Cur), which were prepared by the dialysis method. GACS-Cur was encapsulated with the membranes from red blood cells (RBCm) termed GACS-Cur@RBCm, which were prepared by the principle of extrusion using a miniature extruder. The developed formulations were subjected to various in vitro and in vivo evaluation tests. RESULTS The resulting APS nanocarriers supported a favorable drug-loading capacity, biocompatibility, and enhanced synergistic anti-hepatoma effects both in vitro and in vivo. After administration in mice, in vivo imaging results showed that the GACS-Cur and RBCm-coated groups had an obvious stronger tumor tissue targeting ability than the control treatment groups. Additionally, the immunomodulatory effect increased IL-12, TNF-α and IFN-γ expression and CD8+ T cell infiltration (1.9-fold) than that of the saline group. Notably, in comparison with hyaluronic acid (HA) nanocarriers, APS nanocarriers possess higher anti-hepatoma efficiency and targeting capabilities and, thus, should be further studied for a wide range of anti-cancer applications. CONCLUSION Our data demonstrated that APS nanocarriers encapsulated with erythrocyte membrane mighty be a promising clinical method in the development of efficacy, safety and targeting of liver cancer therapy.

Abstract
Receptor-mediated active targeting and tumor microenvironment responsive systems from polymeric micelles have been studied for rapid cellular internalization and triggered drug release. Previously we have constructed redox-responsive polymeric micelles composed of vitamin E succinate conjugated hyaluronic acid (HA-ss-TOS), which are able to actively target CD44 proteins and quickly release loaded drugs upon exposure to high levels of glutathione (GSH) in tumor cells. In the present study, we found that despite different cellular internalization mechanisms, micelles showed strong antineoplastic effects on 4T1 and B16F10 cells due to redox responsiveness. HA-ss-TOS-PTX micelles exhibited an excellent tumor targeting ability and prolonged retention time compared to Taxol in vivo. In addition, a superior antitumor effect was achieved compared to PTX-loaded insensitive micelles (HA-TOS-PTX) and Taxol. Our results revealed that PTX-loaded HA-ss-TOS micelles could enhance the antineoplastic efficacy of PTX for breast cancer and melanoma treatment and, thus, deserve further attention.

Abstract
Anti-inflammatory drugs such as dexamethasone (DEX) are commonly administered to cancer patients along with anticancer drugs, however, the effect of DEX on human cancers is poorly understood. In this article, we have tailored self-assembled nanoparticles derived from hyaluronic acid (HA) wherein, anti-inflammatory DEX was used as a hydrophobic moiety for inducing amphiphilicity. The HA-DEX micelles were subsequently loaded with chemotherapeutic agent, doxorubicin (DOX) (HA-DEX-DOX) and was utilized to deliver drug cargo to human cancer cells expressing different levels of CD44 receptors. We found that DEX suppressed the cytotoxicity of DOX in HCT116, while it synergistically enhanced cytotoxicity in MCF-7 cells. When we tested DOX and HA-DEX-DOX in an ex-vivo human whole blood, we found activation of complement and the coagulation cascade in one group of donors. Encapsulation of DOX within the nanoparticle core eliminated such deleterious side-effects. The HA-DEX-DOX also polarized bone-marrow-derived anti-inflammatory M2 macrophages, to pro-inflammatory M1 phenotype with the upregulation of the cytokines TNF-α, iNOS and IL-1β.

Abstract
The cellular transport process of DNA is hampered by cell membrane barriers, and hence, a delivery vehicle is essential for realizing the potential benefits of gene therapy to combat a variety of genetic diseases. Virus-based vehicles are effective, although immunogenicity, toxicity and cancer formation are among the major limitations of this approach. Cationic polymers, such as polyethyleneimine are capable of condensing DNA to nanoparticles and facilitate gene delivery. Lack of biodegradation of polymeric gene delivery vehicles poses significant toxicity because of the accumulation of polymers in the tissue. Many attempts have been made to develop biodegradable polymers for gene delivery by modifying existing polymers and/or using natural biodegradable polymers. This review summarizes mechanistic aspects of gene delivery and the development of biodegradable polymers for gene delivery.

Abstract
Natural polysaccharides are frequently used in the design of drug delivery systems due to their biocompatibility, biodegradability, and low toxicity. Moreover, they are diverse in structure, size, and charge, and their chemical functional groups can be easily modified to match the needs of the final application and mode of administration. This review focuses on polysaccharidic nanocarriers based on chitosan and hyaluronic acid for small interfering RNA (siRNA) delivery, which are highly positively and negatively charged, respectively. The key properties, strengths, and drawbacks of each polysaccharide are discussed. In addition, their use as efficient nanodelivery systems for gene silencing applications is put into context using the most recent examples from the literature. The latest advances in this field illustrate effectively how chitosan and hyaluronic acid can be modified or associated with other molecules in order to overcome their limitations to produce optimized siRNA delivery systems with promising in vitro and in vivo results.

Abstract
Because of their inherent biocompatibility and tailorable network design, hydrogels meet an increasing interest as biomaterials for the fabrication of controlled drug delivery devices. In this regard, mathematical modeling can highlight release mechanisms and governing phenomena, thus gaining a key role as complementary tool for experimental activity. Starting from the seminal contribution given by Flory-Rehner equation back in 1943 for the determination of matrix structural properties, over more than 70 years, hydrogel modeling has not only taken advantage of new theories and the increasing computational power, but also of the methods offered by computational chemistry, which provide details at the fundamental molecular level. Simulation techniques such as molecular dynamics act as a "computational microscope" and allow for obtaining a new and deeper understanding of the specific interactions between the solute and the polymer, opening new exciting possibilities for an in silico network design at the molecular scale. Moreover, system modeling constitutes an essential step within the "safety by design" paradigm that is becoming one of the new regulatory standard requirements also in the field-controlled release devices. This review aims at providing a summary of the most frequently used modeling approaches (molecular dynamics, coarse-grained models, Brownian dynamics, dissipative particle dynamics, Monte Carlo simulations, and mass conservation equations), which are here classified according to the characteristic length scale. The outcomes and the opportunities of each approach are compared and discussed with selected examples from literature.

MOLECULAR THERAPY-NUCLEIC ACIDS 2019; 16:597-604. [PMID: 31085353 PMCID: PMC6517641 DOI: 10.1016/j.omtn.2019.04.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 04/12/2019] [Accepted: 04/12/2019] [Indexed: 12/31/2022]
Abstract
We developed a novel miRNA design that significantly improves strand selection within the RISC complex by engineering the 3' end by adding extra nucleotides. Addition of seven nucleotides at the 3' ends of the miR or miR* strand resulted in a thermodynamic asymmetry at either of the two ends, which resulted in selective RISC recruitment, as demonstrated by a stem-loop PCR experiment. Such selective recruitment was also corroborated at the protein level by western blot analysis. To investigate the functional effect because of selective recruitment, we performed apoptosis and metastasis studies using human colon carcinoma cells (HCT116) and human osteosarcoma cells (MG63). These experiments indicated that recruitment of the miR strand is responsible for inducing apoptosis and inhibiting the invasiveness of cancer cells. Recruitment of the miR* strand, on the other hand, had the opposite effect. To the best of our knowledge, our strand engineering strategy is the first report of improved strand selection of a desired miRNA strand by RISC without using any chemical modifications or mismatches. We believe that such structural modifications of miR34a could mitigate some of the off-target effects of miRNA therapy and would also allow a better understanding of sequence-specific gene regulation. Such a design could also be adapted to other miRNAs to enhance their therapeutic potential.

Abstract
Small interfering RNAs (siRNAs) are powerful tools for post-transcriptional gene silencing, which offers enormous opportunities for tissue engineering applications. However, poor serum stability, inefficient intracellular delivery, and inevitable toxicity of transfection reagents are the key barriers for their clinical translation. Thus, innovative strategies that allow safe and efficient intracellular delivery of the nucleic acid drugs at the desired site is urgently needed for a smooth clinical translation of therapeutically appealing siRNA-based technology. In this regard, we have developed an innovative siRNA transfection protocol that employs a short incubation time of just 5 min. This allows easy transfection in suspension followed by transplantation of the cells in a hyaluronic acid (HA) hydrogel system. We also report here the unique ability of siRNA to bind HA that was quantified by siRNA release and rheological characterization of the HA-hydrogel. Such interactions also showed promising results to deliver functional siRNA in suspension transfection conditions within 30 min using native HA, although removal of excess HA by centrifugation seem to be essential. In the 2D experiments, suspension transfection of hMSCs with RNAiMAX resulted in ≈90% gene silencing (with or without removal of the excess reagent by centrifugation), while HA demonstrated a modest ≈40% gene silencing after removal of excess reagent after 30 min. Transplantation of such transfected cells in the HA-hydrogel system demonstrated an improved knockdown (≈90% and ≈60% with RNAiMAX and HA respectively after 48 h), with lower cytotoxicity (up to 5-days) as determined by PrestoBlue assay. The gene silencing efficiency in the 2D and 3D conditions were also confirmed at the protein levels by Western blot analysis. We postulate this novel transfection method could be applied for in vivo applications as it allows minimal manipulation of cells that are to be transplanted and reduce toxicity.
