Web20 de abr. de 2024 · The “seed” cell of every oocyte is the primordial germ cell. These are embryonic cells that will eventually become either sperm or oocyte cells. In the developing embryo, these cells move into the area that will eventually become either the testis or ovaries (also known as the gonads). WebThe creation of oocytes in adult life from hemopoietic stem cells appears possible (Johnson et al., 2004, 2005), however, they have been reported not to contribute to any of the cohort of mature ovulated oocytes (Eggan et al., 2006); therefore their function remains enigmatic and is not discussed further. rayco rg 50
