    Abstract : In mice, primordial germ cells (PGCs) dramatically increase in their number from 200 cells at 9.5 dpc to 10 000 cells at 12.5 dpc with doubling time of 12.6 hours. READ MORE

  4. 2. Signaling pathways in the development of female germ cells

    Author : Deepak Adhikari; Kui Liu; Elisabet Stener-Victorin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ovary; primordial follicle; activation; mTORC₁; PI₃K; oocyte maturation; MPF; Cdk₁; medicinsk biokemi; Medical Biochemistry;

    Abstract : Primordial follicles are the first small follicles to appear in the mammalian ovary. Women are born with a fixed number of primordial follicles in the ovaries. Once formed, the pool of primordial follicles serves as a source of developing follicles and oocytes. READ MORE

  5. 3. Gonad development and male gametogenesis

    Author : Christina Österlund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Testicular and ovarian organogenesis involve a pathway of developmental genes which are differentially regulated in males and females. In mammals, sex determination is controlled by a dominant gene, SRY, located on the Y chromosome. READ MORE

  6. 4. The human ovary : a characterization of cell types and adverse ovarian side effects of chemotherapy

    Author : Magdalena Wagner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human ovary has a major role in the body’s endocrine and reproductive system. Understanding its cell type composition is crucial in order to study underlying mechanisms of hormonal balance and ovarian follicle maturation in health and disease. The outer lining of the ovary, the cortex, harbors the ovarian reserve. READ MORE
