This research presents a detailed spatial transcriptomic atlas of small cell lung cancer (SCLC) to identify how the tumor microenvironment evolves during lymph node metastasis. By examining over 600,000 individual cells from 75 patients, the study identifies three specific malignant subclusters that appear during metastasis and exhibit unique metabolic and immune-evading properties. The authors de...去小宇宙查看完整单集简介

The paper introduces SMART, an unsupervised deep learning framework designed to integrate spatial multi-omics data into a unified representation. By combining graph neural networks with metric learning, the model effectively captures both local spatial contexts and long-distance biological similarities across various omics layers. The researchers developed a variant called SMART-MS to align data a...去小宇宙查看完整单集简介

The article examines how fibroblast cells orchestrate inflammaging, the chronic pro-inflammatory state associated with aging. The study identifies that the activation of the NF-κB signaling pathway in these structural cells triggers a biological circuit involving macrophages and T cells, leading to the formation of organized immune aggregates in the lungs. This process promotes the emergence of sp...去小宇宙查看完整单集简介

This research identifies a specific 3D morphogenetic blueprint called Metastatic Trabecular Morphogenesis (MTM) that is essential for breast cancer spread. By utilizing single-cell RNA sequencing and AI-supported 3D imaging, scientists discovered that aggressive cancer cells reactivate fetal developmental programs to build complex, branching lattices of epithelial cords. These MTM-high states are ...去小宇宙查看完整单集简介

Researchers have developed a Perturb-seq platform to systematically identify and rank genetic barriers that prevent the conversion of fibroblasts into functional heart muscle cells following a heart attack. By screening 140 potential inhibitors in a living mouse model, the study pinpointed calreticulin (Calr) as the primary obstacle to successful cardiac regeneration. High levels of this protein i...去小宇宙查看完整单集简介

Researchers have developed the TK4 PiggyBac vector to solve the common problem of transgene silencing during the differentiation of human pluripotent stem cells. While many genetic constructs work in undifferentiated cells, they often lose functionality as those cells become mature neurons or microglia. This study identifies that combining CAG or Ubc promoters with the WPRE regulatory element effe...去小宇宙查看完整单集简介
