A Synovium‐on‐Chip Platform to Study Multicellular Interactions in Arthritis
Advanced Healthcare Materials, EarlyView.The Synovium‐on‐Chip comprises a thin microporous PDMS membrane to support co‐culture of fibroblast‐like synoviocytes (FLS), THP‐1‐derived macrophages, and endothelial cells, enabling real‐time analysis of synovial‐vascular interactions. FLS migration through the pores drives endothelial remodeling, while TNF‐α stimulation induces robust inflammatory ...

One-step Deposition of Melanin-like Polymer on individual Escherichia Coli cells Exhibiting an Special Effect of UV- and Lysozyme - Resistance [PDF]
, 2015 尽管紫外线只占到达地球表面的阳光辐射能量中的一小部分，但若长期暴露于这部分紫外辐射之下，几乎所有的有机生命体都将直接或间接地因受到光损伤而导致其遗传物质核酸遭受破坏，进而造成机体死亡。为了应对太阳光中的这部分紫外辐射，某些微生物已经进化出了许多生物化学或生物行为光保护机制。黑色素，由于其具有很强光吸收和良好能量转换性质，可以将有害辐射能高效地转换为热能进而耗散至周围环境中，黑色素一直被认为是所有已知的光保护机制中最高效的。因此，结合黑色素的性质，人们可以使用其来提高某些生物工程菌的抗紫外性能 ...
