查询词典 progenitors

METHODS: Otocyst epithelia surgically isolated from fetal rats were cultured and passaged. Proliferation and differentiation of cultured cells were observed using BrdU labeling to find the progenitors. Immunocytochemistry (Factin, cytokeratin and calretinin) was used to detect cell properties of cultured cells.

取孕鼠胚胎听囊细胞进行体外培养，用免疫细胞化学方法，分别对培养的细胞进行细胞角蛋白、F肌动蛋白和calretinin染色观察细胞特征；BrdU染色观察细胞增殖。

以这些序列为探针对大量的多倍体小麦和它们的二倍体祖先物种进行了Southern杂交分析。

Powered by the progenitors of today's PCs, PROMIS, from its first "testdrive" a quarter century ago, was able to do one thing that no other

无论从巨大的大型计算机系统或通过今天的个人电脑，从第一的PROMIS"试驾"四分之一世纪前，祖细胞的工作动力较小的网络，能够做一件事

According to Hesiod's "Eoiae" or "Catalogue of Women" on the origin of the Greeks, Pandora (named after her grandmother Pandora, sister of Hellen and daughter of Deukalion and Pyrrha) together with Zeus had three sons: Graecus, Magnetas and Macedon who together with Hellen's three sons Dorus, Xuthus and Aeolos, comprised the set of progenitors of the ancient tribes that formed the Greek/Hellenic nation.

中文译名，苏瑟斯，苏托斯在古希腊神话中，xuthus是海伦Hellen和Orseis的儿子，是生活在雅典的爱奥尼亚人的祖先。他和Creusa有两个儿子Ion和Achaeus以及一个女儿，名叫Diomede。得到古希腊著名勇士阿喀琉斯的照顾。

I believe that each of these great inventions—language, the family,the use of tools, government, science, art, and philosophy—has thequality of so combining the potentialities of every human temperament,that each can be learned and perpetuated by any group of human beings,regardless of race, and regardless of the type of civilization withinwhich their progenitors lived; so that a newborn infant from the mostprimitive tribe in New Guinea is as intrinsically capable of graduationfrom Harvard, or writing a sonnet, or inventing a new form of radar asan infant born on Beacon Hill.

过去，孩子们通常会玩这样的游戏——突然指着一个人说："你是干什么的？"有些人会回答："我是一个人。"或回答是哪国人，或是哪个宗教的信徒。当新一代的孩子这样问我时，我答道："我是一个人类学家。"人类学是对人类所有生活方式的研究，需要一个人将全部的精力与时间都投入其中。所以，在谈论信仰时，我无法将自己作为一个人的信仰与作为一个人类学家的信仰区分开来。

Results:(1)NSCs form typical neurospheres under adequate concentration in vitro, which are immunoreactive to Vimentin. Typically and terminally differentiated mature neural cells could not be found without the stimulus of mitogen or only under NSCs self-regulation and self-induction;(2)NSCs derived from hippocampus maintain the character of stem cells much longer with better biological behavior; NSCs passed to the 2-3 passage are the best to graft since they have not differentiated;(3)NSCs cultured in vitro could self-regulate and differentiate into neurospheres and progenitors positively immunoreactive to specific antibodies representing neurons, astrocytes, oligodendrocytes and Schwann cells;(4)There are widespread synaptic contacts between various kinds of descendent clones and cells;(5)Neurospheres could be formed without the stimulus of mitogen when NSCs and OECs are cocultured. Many neurospheres and cells immunoreactive to Vimentin, GFAP, MAP2, 02, p75NGFR, GFAP, S-100, Synaptosis, Vimentin, Tau (Tau is only positive in cocultureof HNSCs+HOECs) could be found;(6)The supernatant fluid triturated from adult rat spinal cord stimulates NSCs to differentiate into neurons, but do not terminally differentiate;(7)Fibroblasts and O4 oligodendrocytes are not supported to grow under this culture medium.Part II: Isolation, culture and identification of rat and human olfactory ensheathing cellsOlfactory ensheathing cells/glials are the most powerful cells to enable the regeneration of axons in the central nervous system.

结果表明：①在适宜的浓度体外培养条件下，NSCs能形成典型的神经干细胞克隆球，Vimentin免疫荧光染色阳性，单靠丝裂原刺激或NSCs自我调节和分化诱导，不会产生典型的终末分化的成熟神经细胞；②海马源性的NSCs维持干细胞特性的时间更长，生物学特性更优；③传至第2～3代的NSCs尚未分化时移植最佳；④体外培养的NSCs能自我调控分化为神经元、星形胶质细胞、O2少突胶质细胞、雪旺氏细胞染色阳性克隆球和前体细胞；⑤各种子代克隆球和细胞存在广泛的突触联系；⑥NSCs与OECs联合培养时，不需丝裂原刺激即能形成克隆球，获得大量Vimentin、GFAP、MAP2、O2、p75NGFR、GFAP、S-100、Synaptosis、Vimentin、Tau(Tau只有人HNSCs+HOECs联合培养时出现阳染)染色阳性的克隆球和细胞；⑦脊髓研磨后的上清液刺激神经干细胞向神经元方向分化，但并不出现终末分化；⑧本研究培养条件不利于成纤维细胞、O4生长。

Jagged1 increases the number of bipotent colony-forming unit-granulocyte macrophage and unipotent progenitors (CFU-granulocytes and CFU-macrophages), without quantitatiely affecting terminal cell differentiation, whereas Delta1 reduces the number of CFU-GM and differentiated monocytic cells.

Jagged1增加双潜能细胞和单潜能祖细胞（CFU-G和CFU-M）的数量，而并不影响终末分化细胞的数量；另一方面，Delta1减少CFU-GM和分化的单核细胞数量。
