亚麻下胚轴产生愈伤组织过程中,细胞发育进程相差很大,增生能力有明显不同。从诱导分裂到小分生细胞团形成,增殖细胞形态特征变化显著,体积随分裂次数增加而下降,原生质体积密度和核质指数不断升高;核和核仁体积在诱导分裂期剧增,以后缓慢下降。小分生细胞团时期细胞形态特征相似,分裂生长快。愈伤组织形成中细胞向薄壁细胞发育。根据细胞增生能力和形态变化,得出亚麻下胚轴细胞脱分化阶段从诱导分裂开始,到小分生细胞团形成结束;愈伤组织形成时期细胞发生再分化。

An anti-nucleolar antiserium is successfully raised in rabbits. The nature of the nucleolar antigen(s) (NAg-1) is investigated. Indirect immunofluorescent staining and cytochemical analysis suggest that the MAg-1 is an (are) acidic protein(s), complexed with DNA and related to rRNA synthesis. Strong nucleolar fluorescence is observed in human cancer cells and proliferating cells but not in normal human lymphocytes and non-proliferating tissues. The nucleolar antigen(s) is (are) not detected in the cells of mouse....

An anti-nucleolar antiserium is successfully raised in rabbits. The nature of the nucleolar antigen(s) (NAg-1) is investigated. Indirect immunofluorescent staining and cytochemical analysis suggest that the MAg-1 is an (are) acidic protein(s), complexed with DNA and related to rRNA synthesis. Strong nucleolar fluorescence is observed in human cancer cells and proliferating cells but not in normal human lymphocytes and non-proliferating tissues. The nucleolar antigen(s) is (are) not detected in the cells of mouse. Using human promyelocytic tumor cells line HL-60 it is shown that those with a higher speed of growth possesses higher percentages of NAg-1 positive cells than the group with a slower growth rate. With the increase of cell density the percentage of NAg-1 positive cells decline. These preliminary studies demonstrate that the NAg-1 antigen(s) is (are) associated with cell proliferation.

用自制的抗核仁抗原的抗血清对其相应的核仁抗原(NAg-1)进行了研究.间接免疫荧光染色及细胞化学分析表明,NAg-1,可能是一种与DNA结合并与rDNA合成有关的酸性蛋白质.其在静止的人淋巴细胞和人正常非增殖组织中基本不表达或仅有微量表达,在人癌细胞和人正常增殖细胞中表达.并具有一定的种属特异性.NAg-1在快速增殖的HL-60细胞中表达的百分比大大高于缓慢增殖的细胞.随着HL-60细胞的密度增大,其细胞核仁抗原表达的百分比大大下降,说明NAg-1与细胞的增殖相关.

The wild celery (Angelica polymorpha Maxim.) was employed as the experimantal ma- terial to study the initiation of the embryogenic cells and the ontogeny of the proembryoids in petiole explants examined with light and electron microscopy. Segments of petioles were cul- lured on the surface of MS medium (MS + 2,4-D 2mg/L + KT 0.25mg/L), and then the DNA synthetic activity and cell divisions were examined to confirm that in which cell depar- ture from quiescent state and initiation of cell division occurred....

The wild celery (Angelica polymorpha Maxim.) was employed as the experimantal ma- terial to study the initiation of the embryogenic cells and the ontogeny of the proembryoids in petiole explants examined with light and electron microscopy. Segments of petioles were cul- lured on the surface of MS medium (MS + 2,4-D 2mg/L + KT 0.25mg/L), and then the DNA synthetic activity and cell divisions were examined to confirm that in which cell depar- ture from quiescent state and initiation of cell division occurred. Results show that the proe- mbryoids originate from the innermost layer of cortex parenchyma cells which exhibit rapid periclinal and anticlinal divisions, then a pericyclic tissue composed of 2-3 layers of smaller but still vacuolate cells form and corrugately cover the vascular bundle. Soon after that, indi- vidual cell groups located in the inner region of this tissue undergo regressive change and asyn- chronously transform to embryogenic clusters, giving rise to nodule-like proembryoids by re- peated cell divisions. Meanwhile, the phloem parenchyma cells also proliferate by mitosis. Ac- companying with some original sieve tube degeneration, a number of new sieve elements diffe- rentiated from the newly formed parenchyma cells. Microscopic observations also reveal that a lot of new tracheary elements differentiated from the xylem parenchyma cells. Evidently, the re-differentiation of the vascular elements in the petiole explants reflects the intensification of nutrient translocation in these segments in close relation to the great demand for nutrients du- ring the ontogeny of proembryoid.

通过光学与电子显微镜观察研究了野芹菜(Angelica polymorpha Maxim.)叶柄外植体胚性细胞的起源与原胚状体的发生。叶柄切段植入 MS+2mg/L2,4-D+0.25 mg/L KT固体培养基后,以DNA合成和细胞分裂为指标,判明了胚状体发生与紧贴维管束的鞘细胞层密切相关;鞘细胞通过有丝分裂形成多层结构的细胞群,它们仍含大液泡及薄层胞质,成片被覆在维管束表面;胚性细胞团即不同步地发生在该多层组织较内层的局部位点上,细胞具大核,胞质稠密,经持续有丝分裂发展成大小不同呈瘤状突起的原胚状体。伴随着鞘细胞的剧烈变化,韧皮部薄壁细胞亦分裂增殖,原有筛管变形衰退,部分新增殖的细胞分化为新筛分子;木质部中,原导管束附近朝向韧皮部一侧的部分薄壁细胞亦进一步分化为孔纹导管。外植体中维管系统的再次分化,显然是与输导功能强化以适应原胚状体发生时对营养物质的大量需求有关。
