Efficient genome editing in ASC-derived porcine lung organoids via GFP-guided enrichment

Beom-Jin Jeon, Byeongho Moon, H D Jang, Dong-Hyeok Kwon et autres

Adult stem cell-derived organoids are invaluable tools for disease modeling and translational medicine owing to their tissue-specific correspondence. However, their complex three-dimensional structure and low genome-editing efficiency have posed significant challenges for functional genetic studies. To address these limitations, this study aimed …

Rotational Stacking Faults as a Hidden Origin of Electrochemomechanical Failure in High-Energy Layered Oxides

H D Jang, Kisuk Kang

Electrochemomechanical degradation is widely recognized as the primary failure mechanism in high-energy layered oxide cathodes, yet the fundamental structural trigger that initiates this process has remained unresolved. Here, we, for the first time, identify rotational stacking faults in the layered oxide frameworks, …

Injectable Short Nanofiber Fragments Enable Conformal Fibrous Scaffolds for Tissue Engineering on Complex Surfaces

Iruthayapandi Selestin Raja, H D Jang, Elif Beyza Demiray, Dongwoo Gi et autres

Polymeric short nanofibers are widely utilized in drug delivery due to their biocompatibility and sustained release properties; however, their application as scaffold-forming biomaterials for tissue engineering remains limited. Here, short nanofiber fragments (SNFs) derived from electrospun poly(D-lactide)/gelatin (PG) nanofiber mats are developed …

MedLayBench-V: A Large-Scale Benchmark for Expert-Lay Semantic Alignment in Medical Vision Language Models

Association for Computational Linguistics 2026, Heeseong Eum, H D Jang, Junhyeok Lee et autres

Medical Vision-Language Models (Med-VLMs) have achieved expert-level proficiency in interpreting diagnostic imaging. However, current models are predominantly trained on professional literature, limiting their ability to communicate findings in the lay register required for patient-centered care. While text-centric research has actively developed resources …
