Researchers at the Max Delbrück Center have successfully generated primordial germ cells from stem cells, a world's first for a large mammalian species. This milestone aims to save the northern white rhino subspecies from extinction through lab-grown egg and sperm cells.
A research team analyzed germ cells in chickens using RNA-sequencing to predict the mechanism that determines sex. The study reveals a mix of cell-autonomous and somatic-cell regulation, with sex determination occurring earlier in females than males.
Scientists have developed a method to maintain human primordial germ cells in culture for at least five months, allowing for the study of their function and development. This breakthrough enables researchers to investigate how exposure to chemicals affects human reproduction and testicular cancer.
Researchers at the University of Tsukuba discovered a male-biased protein expression in primordial germ cells of fruit flies. The study used the Gal4-UAS system to induce gene expression and found that male cells had more protein synthesis occurring, with stronger GFP expression.
Scientists from the University of Tsukuba have developed a new technique to preserve Drosophila primordial germ cells, which can be used to produce new offspring. The cryopreserved PGCs were found to be effective after up to 400 days of long-term storage.
Researchers recreated ovarian follicle structures using mouse embryonic stem cells and successfully matured primordial germ cells into fully functional oocytes. The study provides a model system for studying later events of oogenesis and has implications for assisted reproductive technologies.
A team of biologists and mathematicians developed a new software tool to analyze cell migration processes in zebrafish embryos. The study identified physical barriers that influence cell migration and found a tissue-specific expression of green fluorescent protein, which serves as a reference structure for image registration.
Researchers at UT Southwestern Medical Center have derived a new intermediate embryonic stem cell type that can contribute to chimeras and create precursors to sperm and eggs in culture. This discovery could lead to advances in basic biology, regenerative medicine, and reproductive technology.
Researchers successfully used CRISPR/Cas9 gene editing to delete a specific protein necessary for avian leukosis virus subgroup J infection in chickens. The edited cells were then bred to create resistant chickens, addressing a major concern for the poultry industry.
Researchers at the University of Cologne have found that somatic niche cells surrounding primordial germ cells (PGCs) control their response to DNA damage. This discovery sheds new light on how PGCs maintain genome integrity, potentially improving understanding of inheritance and infertility.
Researchers developed a method to generate primordial germ cell 'lookalike' cells, enabling the study of early stages of specification and regulation of developmental timings. This breakthrough opens up new avenues for understanding transgenerational epigenetic inheritance in humans.
A study published in Cell has described the comprehensive erasure of epigenetic information in early primordial germ cells prior to egg and sperm formation. However, researchers found that around 5% of DNA remains resistant to reprogramming, potentially contributing to conditions such as schizophrenia and obesity.
Scientists at Weizmann Institute and Cambridge University successfully created human primordial germ cells, the earliest precursors of sperm and ova, in a lab. The breakthrough method could help address fertility issues and potentially enable new reproductive technologies.
Researchers at the University of Cambridge successfully created primordial germ cells from human embryonic stem cells, a crucial step in early mammalian development. The study identified a critical gene, SOX17, involved in directing human stem cells to become these cells, and showed that PGCs can be made from reprogrammed adult cells.
Researchers at NYU Langone Health have unraveled the signals governing ovarian development, revealing a feedback loop that ensures sufficient primordial germ cells in the ovary. This discovery has implications for understanding organ growth, regeneration, and disease treatment using stem cells.
Researchers found a potential link between testicular cancer and male infertility, suggesting that genetic mutations during fetal development may play a role. The study provides insights into the origins of human testicular cancer, which is a leading cause of cancer in men between 15-39 years old.
A recent study has identified Wunen2 as a crucial guidance molecule in Drosophila germ cell migration, requiring maternal activity to sustain pole cells during migration. The research suggests a new paradigm for explaining the function of lipid phosphate phosphatases in developmental processes.
