31 Οκτ 2023 · Oogenesis. Oogenesis occurs in the outermost layers of the ovaries. As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to one to two million cells in the embryo.
Oogenesis—the differentiation of the ovum—differs from spermatogenesis in several ways. Whereas the gamete formed by spermatogenesis is essentially a motile nucleus, the gamete formed by oogenesis contains all the materials needed to initiate and maintain metabolism and development.
Oogenesis - the process by which female germ cells develop into mature eggs, or ova - is a complex process involving many important elements of developmental and cellular biology: from cell-cell interactions, complex signalling cascades, specialized cell cycles and cytoskeleton organization.
In many species, the female gonad is essential for germ cells to initiate and carry out oogenesis. This is not true for nematodes, since some mutations that alter the sperm/oocyte decision cause males to make oocytes (for examples, see Barton and Kimble, 1990; Ellis and Kimble, 1995).
