Despite its potential, immunotherapy faces challenges related to delivery efficiency and off‐target toxicity of immunotherapeutic drugs. Nano drug delivery systems offer improvements in drug biodistribution and release kinetics but still suffer from shortcomings such as high immunogenicity, poor penetration across biological barriers, and insufficient tissue permeability. Targeted delivery of drugs using living cells has become an emerging strategy that can take advantage of the inherent characteristics of cells to deal with the delivery defects of nano delivery systems. Furthermore, cells themselves can be genetically engineered into cellular drugs for enhanced immunotherapy. This review provides an in‐depth exploration of cell‐derived drug carriers, detailing their biological properties, functions, and commonly used drug loading strategies. In addition, the role of genetically modified cells in immunotherapy and their synergistic therapeutic effects with drug delivery are also introduced. By summarizing the main advancements and limitations in the field, this review offers insights into the potential of cell‐based drug delivery systems to address the existing challenges in immunotherapy. The introduction to recent developments and evaluation of ongoing research will pave the way for the optimization and widespread adoption of nano/genetically engineered cells for immunotherapy.","PeriodicalId":100191,"journal":{"name":"BMEMat","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This optical property arises due to the combined effects of light absorption and scattering and becomes the main impediment of deep imaging. To overcome these obstacles, the tissue‐clearing technique has experienced a resurgence over the past century and evolved from its initial use in neuroscience to encompass various samples due to the emergence of various clearing methods. Notably, these techniques unveil both macroscopic and microscopic details, offering valuable insights into tissue structures. In particular, the oral cavity is structured with both soft and hard tissues at the macroscopic level and is rich in neurovascular networks microscopically, providing a suitable application environment for tissue‐clearing techniques. Currently, tissue‐clearing techniques have provided a powerful tool for research on the dental pulp neurovascular system, oral tissue regeneration, dental implants, and maxillofacial surgical treatments. Hence, this review aims to give a general introduction to tissue‐clearing techniques and focus on their remarkable applications in dental research. At last, we will discuss the integration of tissue‐clearing methods with other techniques such as labeling and microscopy, hoping to offer valuable insights for the development of tissue‐clearing techniques in both bioscience and materials science.","PeriodicalId":100191,"journal":{"name":"BMEMat","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon extrusion into water and subsequent diffusion of HBD, these ink cure rapidly. The DIPS-printed scaffold retained most of the original hydrogel properties due to the regeneration of hydrogen bonds. Additionally, the reversible nature of hydrogen bonds provides DIPS 3D-printed scaffolds with exceptional recycling and reprinting capabilities, resulting in a reduction in the waste of valuable raw ink materials or additives. Postprocessing introduces new crosslinking methods that modulate the mechanical properties and degradation characteristics of DIPS scaffolds over a broad range. Based on its suitable mechanical properties and bioactivity, we successfully repaired and functionally reconstructed a complex defect in penile erectile tissue using the DIPS scaffold in a rabbit model.
