永生化人牙齦角質形成細胞(Gie-No3B11) (貨號T0049)
Immortalized Human Gingival Keratinocytes (Gie-No3B11)
細胞株介紹: 牙齦上皮保護牙周組織不受細菌和有毒物質的影響。 角質形成細胞通過與細胞骨架和相鄰細胞形成細胞間連接而在促進強上皮鍵方面發揮重要作用。 永生化人類牙齦角質形成細胞是經轉染以表達HPV-16E7的分離的初級口腔角質形成細胞。 它表達細胞角蛋白2,細胞角蛋白17,細胞角蛋白19,包膜蛋白,聚角蛋白和claudin-1。 這些細胞可以通過改變培養條件來建立跨上皮電阻,這是牙齦角質形成細胞的一個獨特特徵。這些細胞被推薦用於有助於牙齦組織特定性質的機制的研究,例如上皮屏障功能。

| Description | The gingival epithelium protects periodontal tissue from bacteria and toxic substances. Keratinocytes play an important role in promoting strong epithelial bonds through the formation of intercellular connections with the cytoskeleton and neighboring cells. The Immortalized Human Gingival Keratinocytes are isolated primary oral keratinocytes transfected to express the HPV-16 E7. It expresses cytokeratin 2, cytokeratin 17, cytokeratin 19, involucrin, filaggrin, and claudin-1. These cells may be differentiated by altering culturing conditions to build transepithelial electrical resistance, a distinct characteristic of gingival keratinocytes. These cells are recommended for studies in mechanisms that contribute to the specific properties of the gingiva tissue, such as the epithelial barrier function. |

Abmgood不朽化系列商品 (immortalized reagenet) Ready-to-use
Abmgood公司於人類與老鼠不朽之細胞株上,具有幾十年的實驗經驗;提供一系列不朽 (immortalized)化之細胞株、及不朽化之試劑商品。ready-to-use定量好之retrovirus、lentiviru、 adenovirus,可直接加於細胞中進行感染表現;病毒液包括有SV40重組病毒、EBV重組病毒、hTERT病毒液、Myc基因病毒液、p53基因病毒液、Rb基因病毒液、Ras基因病毒液。提供106及109兩種包裝力價之病毒液;亦提供一系列病毒力價濃縮與定量試劑商品。
細胞不朽化的工具中,SV40 T antigen是最簡單且最常用來造成不朽化細胞生成的方法。多數的病毒基因和抑癌基因(p53、Rb等)的不活化相關,會誘導細胞處於replicative senescence的階段。目前也有研究顯示被感染的細胞,SV40 T anbtigen會誘導端粒酶(Telomerase)的活性。與端粒(telomere)長度相關的Telomerase Reverse Transcriptase protein (TERT)是一種不朽細胞的研究應用。平常細胞中,hTERT是處於不活化態,必要時會進行活化保持telomere的長度,避免細胞發生replicative senescence的現象。某些細胞hTERT 過度表現(over-expression)對於誘發細胞不朽化是無效的(如初代上皮細胞),反而會造成細胞死亡;同時表現hTERT catalytic subunit以及p53或RB siRNA在人類初代卵巢上皮細胞會造成細胞不朽化。過度表現Ras或Myc T58A mutants也有初代細胞不朽化的現象產生。
