中文拼音 [tàinéngxiānwéi]
肽能纖維
英文
peptidergic fiber-
Moreover, human ghrelin receptor exhibits a remarkable 50 % overall identity with human motilin receptor, therefore it was named as " raotilin - related peptide ". anatomical evidence showed that there are ascending and descending neuronal projections between pvn, bma and lower brain stem ( nts, dmx ), which participate in the regulation of gastric acid secretion and gastrointestinal motility. moreover, pvn is the center of appetite regulatory web
Pvn與低位腦干（延髓迷走復合體）及邊緣系統之間有密切的纖維聯系，且含有多種神經肽，參與胃酸分泌，胃腸活動等多種生理機能的調節，是影響消化道功能與攝食行為的重要中樞部分， pvn內胃動素可促進胃排空和攝食，而新發現的ghrelin /胃動素相關肽是否參與此核區對胃運動的調節機制及其可能的神經通路尚不明了。Cell adhesion to surface of the substrate is essential to development of the anchorage - dependent cells. only after adhering to surface followed by spreading can cells develop and proliferate. most synthetic polymers used as orthopaedic matrix substitute present hydrophobicity, which may correlates to the low degree of cell attachment. modification with cell adhesion protein / peptides can be benificial to the cell adhesion on polymers and then affect the cell proliferation and differentiation. cell attachment to substrate is primarily mediated by integrins, a widely expressed family of heterodimeric surface receptors. most extrcellular matrix proteins such as fibronectin, osteopontin, collagen type i, bone sialoprotein and vitronectin contain an arg - gly - asp ( rgd ) sequence which is specific to the fixation of cell membrane receptors like integrin. the main aim of this research is to measure, assess adhesion, proliferation of rabbit marrow stromal cells ( mscs ) on the polymers coated by fibronectin, collagen type i or biotie gen, which includes : ( 1 ) biologic characteristics of rabbit mscs were observed by two types of separating method in primary culture. ( 2 ) adhesion, proliferation and differentiation of mscs cultured on polymers coated with biotiegen were assessed. ( 3 ) also, adhesion, proliferation and differentiation of mscs were assessed on plga film or porous plga substrates coated with fibronectin, or collagen type i respectively. ( 4 ) bone formation was observed on the porous plga substrates coated with collagen type i in vivo. this research aims to give new way to make novel synthetic bone with cell adhesion and high bone induction capabilities
因此將這些蛋白包被、固定到材料表面，觀察骨組織工程種子細胞mscs細胞的粘附、生長特性是本研究的中心環節，並從以下方面進行探討： （ 1 ）採用不同原代細胞分離方法，研究其對mscs細胞的生物學特性影響。 （ 2 ）檢測基因勝肽膠對mscs細胞粘附、增殖及分化的影響。 （ 3 ）分別採用型膠原及纖維粘連蛋白（ fibronectin ， fn ）包被聚乙醇酸-乳酸共聚物（ poly （ 1actide - co - glycolide ） ， plga ）膜及多孔塊型plga材料，觀察細胞在單層或三維培養狀態下，型膠原及fn對mscs細胞粘附、增殖及向成骨細胞分化效應及能力。
