The menstrual cycle comprises four phases: menstrual, follicular, ovulatory, and luteal. Menstruation marks the shedding of the uterine lining. The follicular phase involves follicle development in the ovary. Ovulation is the release of a mature egg, crucial for fertility. The luteal phase follows, where the ruptured follicle transforms into a temporary endocrine structure. Hormonal fluctuations orchestrate these stages, regulating the uterine environment. Understanding the menstrual cycle aids in reproductive health management.

Scientists Unravel the Mysteries of Human Pancreatic Endocrine Progenitors
The research integrates single-cell imaging and RNA sequencing datasets to study the differentiation and morphogenetic dynamics of human pancreatic endocrine progenitors. The pro-endocrine transcription factor NEUROG3 has heterogeneous peak levels, and all NEUROG3 peak levels can trigger differentiation into hormone-expressing cells. The data-mapping methodology used in the study links dynamic behaviors to transcriptomic signatures. The […]
