Abstract
Corneal neovascularization (CNV) is a common multifactorial sequela of anterior corneal segment inflammation, which could lead to visual impairment and even blindness. The main treatments available are surgical sutures and invasive drug injections, which could cause serious ocular complications. To solve this problem, a thermo-sensitive drug-loaded hydrogel with high transparency was prepared in this study, which could achieve the sustained-release of drugs without affecting normal vision. In briefly, the thermo-sensitive hydrogel (PFNOCMC) was prepared from oxidized carboxymethyl cellulose (OCMC) and aminated poloxamer 407 (PF127-NH2). The results proved the PFNOCMC hydrogels possess high transparency, suitable gel temperature and time. In the CNV model, the PFNOCMC hydrogel loading bone morphogenetic protein 4 (BMP4) showed significant inhibition of CNV, this is due to the hydrogel allowed the drug to stay longer in the target area. The animal experiments on the ocular surface were carried out, which proved the hydrogel had excellent biocompatibility, and could realize the sustained-release of loaded drugs, and had a significant inhibitory effect on the neovascularization after ocular surface surgery. In conclusion, PFNOCMC hydrogels have great potential as sustained-release drug carriers in the biomedical field and provide a new minimally invasive option for the treatment of neovascular ocular diseases.

Bone morphogenetic protein 4 thermosensitive hydrogel inhibits corneal neovascularization by repairing corneal epithelial apical junctional complexes. Mater Today Bio 2024; 24:100944. [PMID: 38269056 PMCID: PMC10806348 DOI: 10.1016/j.mtbio.2024.100944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 12/16/2023] [Accepted: 01/02/2024] [Indexed: 01/26/2024] Open
Abstract
Corneal neovascularization (CNV) is a heavy attribute of blinding disease changes. Existing medications need numerous infusions and have a limited absorption. Investigating novel drugs with safety, efficacy, and convenience is crucial. In this study, we developed a bone morphogenetic protein 4 (BMP4)-loaded poloxamer-oxidized sodium alginate (F127-OSA) thermosensitive hydrogel. The 14 % F127-OSA hydrogel transformed from sol to gel at 31-32 °C, which might extend the application period on the ocular surface. The hydrogel's porous structure and uniform dispersion made it possible for drugs to release gradually. We used a suture-induced rat CNV model to investigate the mechanism of CNV inhibition by hydrogel. We discovered that F127-OSA hydrogel loaded with BMP4 could significantly reduce the length and area of CNV, relieve corneal edema, and stop aberrant epithelial cell proliferation. The hydrogel's efficacy was superior to that of the common solvent group. Additionally, BMP4 thermosensitive hydrogel repaired ultrastructure, including microvilli, intercellular junctions, and damaged apical junctional complexes (AJCs), suggesting a potential mechanism by which the hydrogel prevented CNV formation. In conclusion, our investigation demonstrates that F127-OSA thermosensitive hydrogel loaded with BMP4 can repair corneal epithelial AJCs and is a promising novel medication for the treatment of CNV.

Abstract
Corneal disease is one of the most significant causes of blindness around the world. Presently, corneal transplantation is the only way to treat cornea blindness. It should be noted that the amount of cornea that people donate is so much less than that required (1:70). Therefore, scientists have tried to resolve this problem with tissue engineering and regenerative medicine. Fabricating cornea with traditional methods is difficult due to their unique properties, such as transparency and geometry. Bioprinting is a technology based on additive manufacturing that can use different biomaterials as bioink for tissue engineering, and the emergence of 3D bioprinting presents a clear possibility to overcome this problem. This new technology requires special materials for printing scaffolds with acceptable biocompatibility. Hydrogels have received significant attention in the past 50 years, and they have been distinguished from other materials because of their unique and outstanding properties. Therefore, hydrogels could be a good bioink for the bioprinting of different scaffolds for corneal tissue engineering. In this review, we discuss the use of different types of hydrogel for bioink for corneal tissue engineering and various methods that have been used for bioprinting. Furthermore, the properties of hydrogels and different types of hydrogels are described.

Abstract
It is a huge challenge to construct a nanoprobe that can convert temperature stimulation into monochromatic signal with "turn-on" function. Here, a drug delivery system of berberine (BBR)-loaded hyaluronic acid (HA)-modified-L-cysteine (Cys) grafted (N-isopropylacrylamide) (PNIPAM) was structured. HA-Cys-PN/BBR does not need to introduce other substances or external stimuli, by adjusting the temperature of this system, the fluorescence responsive intensity and reversible reciprocating control of the nanohydrogel with aggregation induced emission (AIE) performance can be realized. In addition, CD44-HA interaction can be used as targeting the delivery of cancer cells, thus, there is a great interest in development of targeting and imaging agents as payloads for tumor tissue therapy. Therefore, it can provide a side of the development with self-released drugs in the therapy of cancers or bacterial infections. Thus, HA-Cys-PN/BBR as AIE reversible nanogel has longer-term applications in biomedical applications.

Abstract
PURPOSE Corneal injury may cause neovascularization and lymphangiogenesis in cornea which have a detrimental effect to vision and even lead to blindness. Bone morphogenetic protein 4 (BMP4) regulates a variety of biological processes, which is closely relevant to the regulation of corneal epithelium and angiogenesis. Herein, we aimed to evaluate the effect of BMP4 on corneal neovascularization (CNV), corneal lymphangiogenesis (CL), corneal epithelial repair, and the role of BMP4/Smad pathway in these processes. METHODS We used MTT assay to determine the optimal concentration of BMP4. The suture method was performed to induce rat CNV and CL. We used ink perfusion and HE staining to visualize the morphological change of CNV, and utilized RT-qPCR and ELISA to investigate the expression of angiogenic factors and lymphangiogenic factors. The effects of BMP4 and anti-VEGF antibody on migration, proliferation and adhesion of corneal epithelium were determined by scratch test, MTT assay and cell adhesion test. RESULTS BMP4 significantly inhibited CNV and possibly CL. Topical BMP4 resulted in increased expression of endogenous BMP4, and decreased expression of angiogenic factors and lymphangiogenic factors. Compared with anti-VEGF antibody, BMP4 enhanced corneal epithelium migration, proliferation and adhesion, which facilitated corneal epithelial injury repair. Simultaneously, these processes could be regulated by BMP4/Smad pathway. CONCLUSIONS Our results demonstrated unreported effects of BMP4 on CNV, CL, and corneal epithelial repair, suggesting that BMP4 may represent a potential therapeutic target in corneal injury repair.

Abstract
With the advantages in biocompatibility, antimicrobial ability, and comparative facile synthesis technology, poly-L-lysine (PLL) has received considerable attention in recent years. Different arrangement forms and structures of the backbone endow lysine-based polymers with versatile applications, especially for ε-poly-L-lysine (EPL) and lysine-based dendrimer (LBD) compounds. This review summarized the advanced development of the synthesis and modification strategies of EPL and LBD, focus on the modification of bio-synthesis and artificial synthesis, respectively. Meanwhile, biomedical fields, where EPL and LBD are mainly utilized, such as agents, adjuvants, or carriers to anti-pathogen or used in tumor or gene therapies, are also introduced. With the deeper of knowledge of pharmacodynamics and pharmacokinetics of the drug system, the design and synthesis of these drugs can be further optimized. Furthermore, the performances of combination with other advanced methodologies and technologies demonstrated that challenges, such as scale production and high expenses, will not hinder the prospective future of lysine-based polymers.
