Nucleome Dynamics and Histone Priming by Pioneer Transcription Factors Drive Osteoblast Differentiation
Cell Press Journals Accepted 3D Genome

Congratulations to Prof. Ki-Tae Kim and Prof. Woo-Jin Kim (Co-corresponding Authors) on the acceptance of this landmark study in Cell Reports, revealing the 3D genomic architecture underlying osteoblast differentiation.

A special congratulations to co-first authors Jae-I Moon and Seung Gwa Park, whose years of dedicated collaboration and relentless effort in the lab made this work possible. Their sustained partnership — spanning experimental design, multi-omics data generation, and mechanistic validation — is the backbone of this publication and a testament to what long-term scientific commitment can achieve.

Functional maturation of osteoblasts from skeletal stem cells requires genome-wide transcriptional reprogramming, coincident with large-scale remodeling of active (A) and inactive (B) chromatin compartments. Using integrative high-throughput 3D genome profiling, the team demonstrated that early osteogenic reprogramming is governed by higher-order 3D genome regulation tightly coupled to A/B compartment remodeling near osteogenic loci.

A key discovery is the concept of histone priming — B-to-A compartment shifts were found to be pre-marked in pre-osteoblasts by active histone modifications before osteogenic induction, indicating that the genome is epigenetically poised for activation prior to differentiation cues. Mechanistically, the study identifies ETS1 as the pioneer factor responsible for recruiting the histone acetyltransferase p300 (EP300) to establish this priming state and drive A-compartment transitions. This stage-specific regulation was validated in both cultured osteoblasts and during embryonic calvarial bone development in vivo, establishing its physiological relevance. This publication establishes a new mechanistic framework connecting pioneer factor activity, histone priming, and global 3D genome reorganization in bone formation — a foundational contribution to skeletal epigenomics.

Immune-Responsive Bioinks Enable Intelligent Vision-Guided In Situ Robotic Bioprinting to Accelerate Diabetic Wound Healing via Macrophage Immunomodulation
IF 19.9 Accepted

Congratulations to Prof. Ki-Tae Kim and Prof. Woo-Jin Kim (Co-corresponding Authors) — a landmark translational study now accepted in Advanced Functional Materials, one of the top-tier materials science journals with an impact factor of 19.9.

This interdisciplinary collaboration spanning multiple international institutions presents a breakthrough platform combining immune-responsive bioinks with vision-guided robotic bioprinting for in situ treatment of diabetic wounds. The system leverages real-time image recognition to autonomously guide a robotic arm in depositing bioink directly onto irregular wound geometries, eliminating the need for pre-fabricated constructs and enabling truly patient-specific therapy at the bedside.

The bioink formulation is engineered to actively modulate the wound immune microenvironment by reprogramming macrophage polarization from pro-inflammatory (M1) to regenerative (M2) phenotypes, a critical bottleneck in chronic diabetic wound healing. The integrated system demonstrated superior wound closure rates, angiogenesis, and tissue remodeling in diabetic animal models, underscoring its potential as a next-generation clinical bioprinting platform.

Co-first authors include Prof. Ki-Tae Kim, Seol-Ha Jeong, and Eleftheria Angeliki Valsam, with Prof. Su Ryon Shin (Harvard Medical School) and Prof. Woo-Jin Kim as co-corresponding authors — a testament to the lab's deepening collaboration with Harvard's Brigham and Women's Hospital.

Long Noncoding RNA MALAT1 Mediates Fibrous Topography-Driven Pathologic Calcification via Myoblast Trans-Differentiation
IF 10.2

Led by Prof. Woo-Jin Kim (First Author), in collaboration with Prof. Kyung Mi Woo and colleagues from SNU and University of Michigan.

This study reveals that lncRNA MALAT1 acts as a key mediator of fibrous topography-induced pathologic calcification — a common complication in cardiovascular implants and soft tissue engineering scaffolds. Fibrous surface architecture was shown to drive trans-differentiation of myoblasts into osteoblast-like cells, and MALAT1 was identified as the central regulatory lncRNA orchestrating this process. Knockdown of MALAT1 effectively suppressed aberrant calcification, highlighting it as a novel therapeutic target for preventing biomaterial-associated ectopic ossification.

Genomic Characterization of Metastatic Pathways in Gastric Cancer
IF 9.1

Led by Prof. Yoon Young Choi (Soonchunhyang University) and Prof. Ki-Tae Kim. The study conducted Whole Exome Sequencing on 99 primary and matched metastatic gastric cancer tumors from 15 patients.

Results revealed that genomic changes differ according to metastatic routes, and genomic characteristics of metastatic tumors have a greater impact on patient prognosis than primary tumors. Reconstructed evolutionary relationships showed distinct patterns — "Branched" and "Diaspora" types — with the Diaspora type exhibiting high tumor heterogeneity, implying poor prognosis due to chemotherapy resistance.
