Outer Membrane Protein YadA of Enteropathogenic Yersiniae Mediates Specific Binding to Cellular but Not Plasma Fibronectin [PDF]

, 1993
The binding of bacteria or bacterial products to host proteins of tissue extracellular matrix may be a mechanism of tissue adherence. We investigated interactions of the plasmid-encoded outer membrane protein YadA, which confers pathogenic functions on ...

An Electron Microscopic Observation on Epithelial Attachment

Nihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 1973
臨床的に正常歯肉と判定し, 光顕で病理組織的に初期歯肉炎とみとめた成人 (20歳～54歳) の辺縁歯肉を, 電子顕微鏡的に観察した。観察は上皮付着部を歯冠側から根尖側の尖端部にわたって行い, その結果次の様な所見を得た。(1) 歯肉溝中央より歯冠側のエナメル質表面には, cuticle に接して上皮細胞がわずかに存在した。cuticle と上皮細胞との間は, 電子密度の低い一層で隔てられ, 両者にはしばしば hemi-desmosome による接合をみとめた。(2) セメント質部の cuticle は, 根尖側にゆくにしたがってその厚さを減じ, 付着上皮の根尖側最尖端の上皮細胞とセメント質との接触部には cuticle をみとめなかった。(3) セメント質表面の cuticle は ...

Development of a porcine multicellular endometrial organoid model for in vitro embryo attachment studies

Journal of Animal Reproduction and Biotechnology
Background: Embryo implantation is a complex process regulated by interactions between endometrial epithelial and stromal cells. The endometrium plays a critical role in this process, providing a supportive environment for embryo attachment.

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair

Advanced Healthcare Materials, EarlyView.
An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...
