結果顯示： eso3細胞在小鼠胚胎成纖維細胞上和或含白血病抑制因於億f ）的es細胞培養液中形成典型的胚胎幹細胞克隆，堿性磷酸酶染色結果為強陽性，具有正常二倍體核型以及具有在體內外分化為三個胚層來源的組織細胞的潛能，而且具有形成種系嵌合動物的能力。At the same time, growth factors have relation to genesis of tumor. fibroblast growth factor ( fgf ) can promote proliferation of tissues derived from mesoderm or neuroectoderm and many tissues and cells can secrete fgf
成纖維細胞生長因子（ fgf ）能夠誘導中胚層和神經外胚層來源細胞的增殖和分化，許多組織和細胞都可以分泌fgf ， fgf可以促進多種細胞的生長和分化。The quality of feeder layer is affected by a lot of factors, such as animal breed, culture medium, passages in vitro and experiment condition, etc. as to the production of feeder layer, there are a few reports about morphological and histologic change when of embryonic body fibroblast when culturing in vitro and cryopreservation, so kunming mouse were chosen as experimental animals and morphological and histologic changes were studied in course of its embryonic body culturing. we expect to offer theoretical foundation to our laboratory for setting up feeder layer storehouse. at the same time, the feasibility of myocardium tissue culturing with fibroblast layer altogether was studied so that established foundation for studied the biological characteristic of heart outside body
小鼠胚體成纖維細胞的培養是制備飼養層的重要途徑，其制備、傳代及冷凍保存均有不同的研究報道，飼養層的質量受許多因素的影響，如動物的品種、培養液、所傳代數及實驗條件等，關于飼養層制備過程中的胚體細胞培養、傳代、冷凍后的細胞形態、組織學等方面的研究報道很少，故本實驗以昆明小白鼠為實驗動物，研究其胚體培養過程中細胞的形態學、組織學等方面的變化，以期為本實驗室建立飼養層細胞庫提供理論依據，同時探討心肌細胞和成纖維細胞層共培養的可行性，以期為心臟生物學特性的體外研究奠定基礎。Marrow stromal cells are adult stem cells from bone marrow that have the potency to differentiate into multiple nonhematopoietic lineages such as bone, cartilage, and lipocyte et al. it also can differentiate into myocytes, hepatocytes, glial cells, and neurons. marrow stromal cell can be easily obtained and have a set of well - developed separation and culture techniques
背景與目的骨髓間充質幹細胞（ mesenchymalstemcells ， mscs ）是具有多向分化潛能的成體幹細胞，除了能向多種中胚層組織細胞分化，如骨軟骨和脂肪細胞外，還可以誘導分化成非中胚層的細胞組織如：神經細胞，肺泡和小腸細胞。In this paper we reported the engagement of cortactin in cell movements in vivo for the first time. we also found that, besides the traditional idea about the role it plays in cell motility, cortactin was also involved in cytokinesis and played undispensensable role in nleava stage independent of arp2 3 complex
這表明皮層蛋白除了傳統意義上了解的參與細胞主動運動外，還在卵裂期發育事二且j中科院碩士學位論文喻丹皮層蛋白（ cortactin ）在斑馬魚早期胚胎發育中的分布圖式和功能分析件中扮演重要角色。Although the cell parameters ( icm and tcn ) of blastocysts of both groups differed significantly ( p < 0. 05 ), the mml 6 + e2 + p group was the closest to the in vivo group, and those of the mm16 group were the lowest
同時添加e2和p的mm16培養液中囊胚的細胞總數、內細胞團數、內細胞團占總細胞的百分率和內細胞團與滋養層細胞數的比率低於體內正常發育囊胚，但顯著高於其它體外培養組（ p 0 . 05 ） 。分享友人
