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.
Proses oogenesis terbagi menjadi tiga tahapan yaitu tahap penggandaan, tahap pertumbuhan dan tahap pematangan (Gambar 1). Tahap penggandaan terjadi pada ovarium janin ketika masih dalam
Oogenesis finds impetus and purpose in casting scientific perspective towards this unique cell for the benefit of scientists and assisted reproductive technology (ART) specialists. The authors of the chapters are distinguished authorities in their respective areas of competence.
1 Δεκ 2012 · Oogenesis is a complex process regulated by a vast number of intra- and extra-ovarian factors. Oogonia, which originate from primordial germ cells, proliferate by mitosis and form primary oocytes that arrest at the prophase stage of the first meiotic division until they are fully-grown.
Oogenesis is a protracted process that encompasses the birth, growth, and maturation of a cell unique in its ability to propagate another generation of organisms. In some sense, it is not a very efficient process when measured in terms of viable offspring.
6 Αυγ 2010 · Folliculogenesis is a protracted process in humans requiring several months from primordial follicle recruitment to large antral follicle formation and ovulation.
Genetic Analysis of Oogenesis and the Role of Maternal Gene Expression in Early Development. Kenneth D. Konrad, Lee Engstrom, Norbert Perrimon, Anthony P. Mahowald
