Folliculogenesis is a multi-faceted and tightly regulated process that includes primordial follicle assembly, follicle development and ovulation (1 6).
The youngest male germ cells, including primordial germ cells and gonocytes, can be used in the construction of diploid embryos by nuclear‐transfer cloning.
"The Dinner Party" consists of a triangular table, 48 feet long on each side, with place settings for 39 notable women, including Primordial Goddess, Sappho, Sojourner Truth and Georgia O'Keeffe.
The turn of the millennium saw the first three-dimensional simulations of primordial star formation that started from cosmological initial conditions and included primordial chemistry networks (e.g. Abel et al. 2002; Bromm et al. 2002).
A nebula contains gas, ice grains and dust (including primordial nuclides).
In addition, pluripotent ES-like cells have been derived from germ cells under proper culturing conditions, including primordial germ cells from the embryo [6] and spermatogonial cells from neonatal or adult testes [7], [8], [9].
Also, the mutant oocytes developed into different kinds of follicles, including primordial, primary, preantral, and antral follicles, and they produced atretic follicles and corpora lutea as shown in Figure 1A.
In two recent papers, however, oocytes in all stages of follicles, including primordial follicles, were labeled by PCNA antibody in adult rat ovaries, and PCNA staining was suggested as a marker for ovarian follicle counts [16], [18].
The process of early gametogenesis requires a succession of coordinated steps, including primordial germ cell (PGC) specification, migration to and colonization of the gonadal ridges, proliferation, and differentiation into more mature gametes [1].
All other follicle populations, including primordial, secondary/growing, healthy, and atretic, were unchanged (data not shown).
