415-人胚胎植入的体外子宫内膜支架模型研究
from 聊聊Sci
这项研究介绍了一种名为 CREST 的创新型人造子宫内膜支架平台，旨在模拟人类胚胎植入的复杂生理过程。通过使用激素引导供体来源的基质细胞和上皮细胞进行分化，该系统成功再现了子宫内膜在月经周期中从增殖期向分泌期转变的关键形态与功能特征。研究证明，CREST 平台能够支持人类胚胎及类囊胚的高效着床与发育，其效果显著优于传统的二维或三维培养模型。利用单细胞转录组测序技术，科学家们揭示了早期植入阶段滋养层与母体组织之间的配体-受体相互作用，并证实了 AXL 信号通路对滋养层向基质扩展的重要性。这一跨学科研究成果不仅为深入探索早期妊娠的“黑箱”提供了实验载体，也为诊断不孕症和开发个体化治疗方案奠定了基础。References: Modeling human embryo implantation in vitroMolè, Matteo A. et al.Cell, Volume 189, Issue 1, 87 - 105.e28前往小宇宙评论区与主播互动

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
