Current treatments primarily slow disease progression and are unable to restore lost retinal cells or visual function, highlighting the need for regenerative therapeutic strategies. Stem cell-based therapies have emerged as a promising approach for retinal repair through multiple mechanisms, including retinal cell replacement, stimulation of endogenous regeneration, cellular reprogramming, immunomodulation, and paracrine signaling. This narrative review provides a comprehensive overview of the major stem cell sources investigated for retinal regeneration. In addition, the roles of extracellular vesicles and retinal organoids as emerging therapeutic platforms are discussed. Particular emphasis is placed on comparing the biological rationale, therapeutic potential, current preclinical and clinical evidence, and translational readiness of each approach. Despite encouraging progress, several challenges continue to limit routine clinical application, including poor survival and integration of transplanted cells, immune rejection, tumorigenicity, genomic instability, variability in differentiation efficiency, manufacturing standardization, and long-term safety. Continued advances in stem cell biology, tissue engineering, gene editing, and clinical trial design are expected to accelerate the development of safe and effective regenerative therapies for retinal diseases.</p>\u0000 </div>","PeriodicalId":134,"journal":{"name":"Biotechnology Journal","volume":"21 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149035785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the utility of three-dimensional (3D) spheroid models as physiologically relevant platforms for investigating these cellular interactions compared with conventional two-dimensional (2D) cultures. By incorporating cancer-associated fibroblasts (CAFs), tumor-associated macrophages (TAMs), endothelial cells, and cancer stem cells (CSCs) into multicellular spheroid systems, these models recapitulate several key features of the TME and provide insights into how signaling mediated by cytokines, exosomes, and direct cell-cell interactions may influence tumor progression. Studies utilizing spheroid models have highlighted processes associated with CAF-mediated CSC enrichment, TAM-driven immune modulation, and endothelial cell-supported niche formation, which have been linked to epithelial–mesenchymal transition (EMT), hypoxic adaptation, and metabolic reprogramming. Furthermore, 3D spheroid systems can reproduce aspects of spatial organization, extracellular matrix (ECM) remodeling, and microenvironmental gradients that are difficult to achieve in traditional 2D cultures and are relevant to the study of therapeutic resistance. The review also discusses recent advances, including microfluidic technologies and co-culture systems, which enhance the investigation of stromal–immune–tumor interactions and may facilitate the identification of potential therapeutic targets. Overall, this review highlights the value of 3D spheroid models as versatile preclinical tools for advancing our understanding of HNSCC biology and supporting the development and evaluation of personalized therapeutic strategies targeting pro-tumorigenic communication networks.</p>\u0000 </div>","PeriodicalId":134,"journal":{"name":"Biotechnology Journal","volume":"21 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148975098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HMSCs were cultured on LbL-coated and untreated microcarriers in up to 500 mL flasks, and were assessed over time, up to 18 days across three seeding densities (2600–20,000 cells/cm²), while yield was assessed at the end of culture.

Herein, using a genetically modified S2 cell line expressing the recombinant rabies virus glycoprotein (RVGP), we investigated the stress caused by RVGP production on S2 cells.

Although RVGP was produced in high amounts, we identified a substrate limitation for rec-S2 cell growth (glutamine), changes in amino acid routes due to RVGP biosynthesis (leucine, serine, glycine, and valine), and metabolites that might be affecting rec-S2 cell growth (acetate, pyruvate, citrate, and malate).

Here, a comprehensive time-series transcriptomic analysis revealed that sodium citrate profoundly influences gene expression across multiple pathways. Sodium citrate supplementation redirects carbon flux toward oxidative energy metabolism by upregulating amino acid biosynthesis, translation, and glycolysis. Crucially, the transcriptional upregulation of argininosuccinate synthase (<i>ARG1</i>) and argininosuccinate lyase (<i>ARG4</i>) was identified as a key node driving fumarate-mediated TCA cycle anaplerosis and ATP supply. This foundational analysis led to the identification of <i>ARG4</i> as a key metabolic engineering target.

Integrated physiological and metabolic flux analysis (MFA) demonstrated that <i>ARG4</i> overexpression redirects metabolic flow, channeling energy substrates toward SAM synthesis, effectively maintaining cellular respiratory metabolism and alleviating energy limitations in the late fermentation phase.
