冠细胞

发根农杆菌Ri质粒诱导的黄芪发状根根冠细胞亚显微结构研究

Subcellular structures of the root cap cells of hairy roots in astragalus membranaceus induced by infection of Agrobacterium rhizogenes

因此，冠细胞内部的二个腔室应该是即将分裂形成的二个细胞。

Therefore , the two highest chamber inside the cell should be split to form the two cells .

青皮、坡垒胚根根据冠细胞富含叶绿体直至萌发早期阶段。

The cells of the root cap of the radicle abound with chloroplast up to early stages of seed germination .

在子房室内，沿珠柄侧的子房内壁生长至与胚珠珠孔相当部位时，花粉管离开子房壁进入珠孔，经珠心冠细胞之间隙抵达胚囊。

The pollen grain germinates on the stigma and the pollen tube grows along the hollow style canal into the ovary chamber at the funicle side and enters the micropyle .

因为卵细胞上的二个冠细胞刚刚被人类发现，目前网上还没有冠细胞的内部结构图，冠细胞内部是不是有二个腔室呢？

Because the two crowns on the egg cell had just been discovered by now the highest online no internal cell structure , the crown inside the cell has two chambers is not it ?

结果：根髓、冠髓细胞均出现碱性磷酸酶染色阳性，染色强度在第5天无差别，在第10、15天根髓染色强度大于冠髓。

RESULTS : Positive staining was found in both root and coronal cells , the ALP activity was equal at 5 days of incubation , but higher in root pulp cells than that of coronal pulp cells after 10 and 15 days of incubation .

作者还比较了在前一种培养基中卵母细胞-放射冠-卵丘细胞复合体和裸卵的体外成熟率，分别为41.8%和7.6%，两者间存在统计学差异（P<0.005）。

The maturation rate of denuded oocytes were 7.6 % which also had significant difference from that of oocyte corona cumulus complexes ( P < 0.005 ) .

目的：比较人牙根髓与冠髓培养细胞的特性，探讨牙髓干细胞在牙髓中的定位。

PURPOSE : This study was aimed to investigate the localization of dental pulp stem cells ( DPSCs ) by comparing the characteristics of cultured dental pulp cells in coronal and root pulp .

方法：运用细胞内微电极技术、Langendorff离体心脏灌流和心率变异性功率谱分析等方法，研究冠心灵对心肌细胞动作电位的影响；

METHODS : Conventional microelectrode technique and Langendorff-perfused guinea-pig hearts were used .
