A germ cell is any cell that gives rise to the gametes of an organism that reproduces sexually. In many animals, the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonads. There, they undergo meiosis, followed by cellular differentiation into mature gametes, either eggs or sperm.

生殖细胞（germ cell）是多细胞生物体内能繁殖后代的细胞的总称，包括从原始生殖细胞直到最终已分化的生殖细胞（精子和卵细胞），其中包含一条性染色体。

2008年2月22日 · Germ cells are the only cell type capable of generating an entirely new organism. In order to execute germline-specific functions and to retain the capacity for totipotency, germ cells repress somatic differentiation, interact with a specialized microenvironment, and use germline-specific networks of RNA regulation.

生殖细胞 （英語： germ cell）是進行 有性生殖 的生物體在產生 配子 的過程中任何一個細胞的總稱。 在許多動物中，原始生殖細胞源自於 胚胎 的 原線，並經由 卵黃囊 區（yolk sac）遷移至原基性腺的 生殖嵴 （genital ridge），並與它作用形成 初級性索 （primary sex ...

Here, I provide my perspective on the key investigations that have led to the in vitro reconstitution of mammalian germ cell development, which will be instrumental in exploring salient themes in germ cell biology and, with further refinements/extensions, in …

2012年10月9日 · Germ cells represent the closest in vivo equivalent to in vitro pluripotent stem cell systems; understanding germ cell biology will provide new insights into the nature of pluripotency.

1999年1月22日 · In this sense, germ cells are the stem cells of the species, since they give rise to organisms rather than organs. They are the means by which species form and change in evolution. In humans (as well as other animals), they are also the vehicles for inherited diseases.

Venom, distributed through the body by the bloodstream, interacts with basophils in the blood and (bottom left) mast cells in tissues. Previous exposure has “primed,” or sensitized, the individual by stimulating these cells to generate immunoglobulin E (IgE) antibodies, which attach to the surfaces of the mast cells and basophils.

Overview Germ cells are a central component of sexual reproduction in animals. They are the route by which the genome and cytoplasmic components are transferred to the next generation. This route utilizes meiosis and gametogenesis, processes that are unique to germ cells.

2015年6月23日 · Germ cells are the special cells in the body that undergo meiosis to generate gametes and subsequently entire new organisms after fertilization, a process that continues generation after...
