水凝胶由于其生物相容性和与天然细胞外基质的结构相似性,已经在再生应用中使用了几十年。最初,这些材料在患者体外形成,并使用侵入性手术技术植入。然而,合成化学和材料科学的进步现在为研究人员提供了一个技术库,通过标准针头输送后,水凝胶形成可以原位发生。这提供了一种微创递送治疗有效载荷、填充复杂组织缺损并诱导身体受损部分再生的途径。在这篇综述中,我们重点介绍了这些可注射治疗性水凝胶生物材料在皮肤伤口修复的药物输送和组织再生方面的应用。
Hydrogels have been utilized in regenerative applications for many decades because of their biocompatibility and similarity in structure to the native extracellular matrix. Initially, these materials were formed outside of the patient and implanted using invasive surgical techniques. However, advances in synthetic chemistry and materials science have now provided researchers with a library of techniques whereby hydrogel formation can occur in situ upon delivery through standard needles. This provides an avenue to minimally invasively deliver therapeutic payloads, fill complex tissue defects, and induce the regeneration of damaged portions of the body. In this review, we highlight these injectable therapeutic hydrogel biomaterials in the context of drug delivery and tissue regeneration for skin wound repair.
