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 …

2017年7月25日 · Somatic cells and germ cells are two basic cell types found in animals. Somatic cells are formed by mitosis during asexual reproduction and germ cells are formed by meiosis …

2008年2月22日 · Germ cells are often described as the ultimate totipotent stem cell. However, germ cells give rise to only sperm or eggs, and it is not until the fertilization of the egg or …

Essentially, germ cells are the embryonic precursors of egg and sperm cells (gametes) involved in sexual reproduction in animals. In vertebrates, these cells originate outside the embryo in early …

Germ cells are the only cells which are transmitted from one generation to the next, and can thus be considered immortal. Germ cells produce highly specialized cells called gametes, which …

Germ cells are a special type of cells that play a central role in sexual reproduction in animals. They differentiate to produce male and female gametes and undergo meiosis to form a haploid …

Germ cells are a source of totipotency and an enduring link between generations, ensuring the transmission of genetic as well as epigenetic information to successive generations. This …

Germ cells are unique as transmitters of both genetic and epigenetic information to subsequent generations, and they show many exceptional properties that are required to fulfill this potential.

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 …

In mammals, the entire population of germ cells that will give rise to all the eggs and sperm for an individual’s lifespan originate early in embryogenesis from a small set of precursor cells that …
