T cell development is a tightly regulated process that transforms immature thymocytes into mature T cells with distinct functionalities. In the thymus, precursor cells undergo a series of selection ...

A new cellular atlas charts, in unprecedented detail, how human B cells are built step by step — and offers a window into how this developmental process goes awry in leukemia. The KAUST-led ...

The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...
