[HTML][HTML] In vitro reconstitution of epigenetic reprogramming in the human germ line

Y Murase, R Yokogawa, Y Yabuta, M Nagano, Y Katou… - Nature, 2024 - nature.com
Epigenetic reprogramming resets parental epigenetic memories and differentiates

ZGLP1 is a determinant for the oogenic fate in mice

SI Nagaoka, F Nakaki, H Miyauchi, Y Nosaka, H Ohta… - Science, 2020 - science.org
INTRODUCTION Mammals generate sexually dimorphic germ cells, oocytes and
spermatozoa, which form the basis for sexual reproduction. Studies in mice have shown that …

[HTML][HTML] Mouse oocytes develop in cysts with the help of nurse cells

W Niu, AC Spradling - Cell, 2022 - cell.com
Mouse germline cysts, on average, develop into six oocytes supported by 24 nurse cells that
transfer cytoplasm and organelles to generate a Balbiani body. We showed that between …

STRA8–RB interaction is required for timely entry of meiosis in mouse female germ cells

R Shimada, Y Kato, N Takeda, S Fujimura… - Nature …, 2023 - nature.com
Meiosis is differently regulated in males and females. In females, germ cells initiate meiosis
within a limited time period in the fetal ovary and undergo a prolonged meiotic arrest until …
