Chordates are bilaterally symmetrical, triploblastic, segmented coelomates which demonstrate a deuterostomic pattern of early embryonic development
脊索動物兩側對稱、三胚層,分節的體腔,在胚胎發育的早期過程中,顯示為后口類型。Ranging from 100 to 200 microns across, the width of several human hairs, these microscopic fossils are surprisingly complex and constitute almost a textbook example of a bilaterian, including the three major tissue layers ( the endoderm, mesoderm and ectoderm familiar from high school biology texts ), the presence of a gut with a mouth and anus, and paired coeloms ( body cavities ) surrounding the gut
這些微化石的大小為100 ~ 200微米,相當于幾根頭發的寬度, ?們看起來出奇復雜,而且簡直就像兩側對稱動物的教科書般,展示了各種特徵:包括三個主要的組織層(內胚層、中胚層及外胚層,都是中學生物課本中熟悉的名詞) ,前後連介面部與肛門的腸腔,腸腔外還圍繞著成對的體腔。It " s shown from the results that the pituitary gland of silurus asotus originates from two embryonic cells of different position ; and the doral wall of the original cavum oris forms the rostral pars distali ( rpd ) and the proximal pars distalis ( ppd ) ; the infundibulum of the ventral part of diencephalons forms the the pars intermedia ( pi ) and the neurohypophsis
結果表明:鯰腦垂體由兩個不同部位的胚胎細胞形成,原始口腔背壁外胚層分離出來的細胞構成腺垂體的前外側部( rpd )和中外側部( ppd ) ,從間腦腹面漏斗體分離出來的細胞構成腺垂體中間部( pi )及神經垂體( nh ) 。A srudy of prenatal diagnosis by ceolocentesis
胚外體腔穿刺術在早期產前診斷應用的初步探討The information generated in current study suggests that the developing influenza ecosystem in southern china region may play an important role in the process of emerging novel influenza viruses, even directly impact the genesis of pandemic influenza strains. materials and methods : fecal, cloacal and tracheal swabs from different types of poultry were collected in live - bird retail markets once a week. they were inoculated into 9 - 11 days embryonated chicken eggs and incubated in 35 for 72 hours
本課題意在: 1 、以pa和cu為代表,探討hgnz亞型流感病毒在這些新形成的小種群中的流行情況; 2 、探討這些小種群中流感病毒的來源:是從其它動物跨種屬傳遞而來,還是本身為流感病毒的天然宿主: 3 、探討這些新形成種群中hgnz亞型流感病毒的進化情況,以及其在整個流感病毒生態體系中的作用;材料和方法:每周採集標本一次,常規處理后,接種於9一n日齡雞胚尿囊腔, 35恆溫培養72小時,收取雞胚尿囊液。These orient themselves so that a fluid-filled cavity, the blastocoel, forms inside the mass of cells.
這些細胞進行自我調整,以致在細胞群內部形成一個充滿液體的腔,即囊胚腔。One chimaeric mouse was produced by injection of es cells into blastocyst of c57bl / 6j. the chimaeric rate of fur colour was about 15 %. fl generations of germ - transmission derived from es cell were not obtained when chimaeric mouse mated with kunming albino mice and c57bl / 6j mice
將胚胎幹細胞注射到c57bl 6j小鼠的囊胚腔內,移植后產生了一隻wk2 -胚胎幹細胞的雄性嵌合體鼠,毛色嵌合率為15左右,成熟後分別與c56bl 6j和昆明白雌鼠交配,均未得到來自es細胞的後代。In contrast to murine studies, studies of human hscs have relied on a number of in vitro assays that identify cells with the capacity to generate hematopoietic progenitors in long - term culture and to differentiation into multiple hematopoietic lineages. recently, two elegant animal models that enable the in vivo measurement of human hscs marrow repopulating potential have been developed. one is the sheep in utero transplantation system in which human hematopoietic progenitor cells are transferred into the sheep fetus in utero before the development of the ovine immune system
早在80年代中期, zanjani等就利用胚胎期免疫系統發育不完善,將人的造血幹細胞移植到妊娠中期胚羊腹腔內,成功地建立了人胎羊造血幹細胞嵌合體移植模型,並以此實驗模型作為體內檢測人造血幹細胞和人骨髓間充質幹細胞多向分化潛能的方法。分享友人
