Ovary growth

Chloroform extracts of pollen can replace many of the initial effects of pollen on ovary growth. Whatever the factor(s) may be, they are nonspecific, for they will cause fruit set in unrelated genera and even unrelated families (Gustafson 1937). Once beyond the critical period following pollination and fertilization, many fruits seem to be self-sufficient for plant hormones. 

Estrogens stimulate cellular proliferation, induce RNA and protein synthesis of uterine endometrium and the fibrous connective tissue framework for ovaries, and increase the size of the cells. This effect leads to the growth and regeneration of the endometrial layer and spinal arterioles, and increase in the number and size of endometrial glands. Under the influence of estrogen, vaginal mucosa becomes thicker, as cervical mucus becomes thinner (85,86). 

Stage IV = Growth involving one or both ovaries with distant metastasis beyond the pelvis (i.e. if pleural effusion present, confirm cytology or any parenchymal liver metastasis equals stage IV). 

The size of egg cells demonstrates that higher eukaryotes have evolved ways to uncouple cell growth and cell cycle progression. The Drosophila egg is about 10 000-fold larger than the stem cells in the ovary. Much of the egg content is... 

Although plant cell culture is not as cost effective as plant cultivation in the open field, it will become an economical process if higher protein yields can be achieved [58]. The cultivation medium of plants is chemically defined, consisting of a carbon source, minerals, vitamins and phytohormones [69]. Furthermore, it is protein-free and relatively inexpensive. In contrast, animal cells often require complex supplements such as fetal calf serum and/or expensive growth factors, although serum-free cultivation is possible in case of Chinese hamster ovary (CHO) cells [70].

Chinese hamster ovary cells in which there has been an extensive rearrangement of chromosome material and the chromosome number may not be constant from cell to cell, are frequently used. Polyploidy, endoreduplication and high spontaneous chromosome aberration frequencies can sometimes be found in these established cell lines, but careful cell culture techniques should minimize such effects. Cells should be treated in exponential growth when cells are in all stages of the cell cycle. 

After pollination, seeds begin to form within the flower s ovary. Meanwhile, each moth egg deep inside the ovary hatches to a minute larva. The larva consumes several yucca seeds to support its growth but leaves behind many more that can go on to propagate the plant. Once a larva matures, it makes its way out of the...
