MiR‐21‐5p Protects Embryonic Growth and Heart Function During Developmental Hypoxia by Dampening HIF Responses and Altering Gene Expression

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
miR‐21‐5p protects embryonic growth and heart function during developmental hypoxia by dampening HIF responses and shifting gene networks toward improved cardiomyocyte survival and calcium handling. This work identifies miR‐21‐5p as a promising therapeutic target for preventing fetal growth restriction and cardiovascular impairment in high‐risk ...

Single‐Cell Sequencing Reveals That CCL2+ Adipose‐Derived Stem Cells Promote Diabetic Wound Healing Through the CCL2‐ACKR1 Signaling Axis

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
scRNA‐seq of human adipose and diabetic wounds revealed a CCL2+ ADSC subpopulation with high stemness and ECM‐enriched pathways. These cells serve as a signaling hub via TGFB1‐TGFBR1, IL34‐CSF1R, and CCL2‐ACKR1. Their exosomes (CCL2‐Exos), carrying CCL2, TGFB1, and IL34, accelerate diabetic wound healing in mice by promoting angiogenesis, collagen ...

Unraveling the Effect of Tramp Elements on Phase Transformations in Steels by Combining CALPHAD Modeling and Experiments

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This study investigates how tramp elements from increased scrap usage influence phase transformations in low‐alloyed steel. Combining dilatometry and microscopy reveal that tramp elements delay transformations, reduce critical cooling rates and increase hardenability.

Nuclear Mechanotransduction Across the Metastatic Cascade: Decoding Spatiotemporal Heterogeneity in Cancer Dissemination

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Tumor metastasis results from complex interactions between cancer cells and mechanical microenvironments. We propose a “nucleus‐centered, cross‐stage mechanical signal decoding” model, highlighting how nuclear mechanosensors interpret forces at different stages.

Robot‐Assisted Doppler Optical Coherence Tomography for Intraoperative Evaluation of Microvascular Anastomoses

Advanced Intelligent Systems, Volume 8, Issue 5, May 2026.
This work presents a robot‐assisted Doppler optical coherence tomography system for autonomous, wide‐field intraoperative assessment of microvascular anastomoses. Machine‐vision–guided probe positioning and adaptive scan planning enable three‐dimensional structural and hemodynamic imaging over extended vessel segments.

Marfan Syndrome Associated With Intellectual Disability and Behavioral Anomalies: Further Evidence for the Effect of Compound Heterozygous Variants in FBN1 on Phenotypic Severity

American Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 1021-1035, May 2026.
ABSTRACT Marfan syndrome (MFS) is a rare connective tissue disorder characterized by involvement of the cardiovascular, ocular, and musculoskeletal systems. Pathogenic variants in FBN1 cause most of the MFS cases; however, intellectual disability (ID) is rarely observed. A non‐consanguineous Pakistani family with four affected individuals was recruited.
