Cell competition in the thymus is crucial in a healthy organism

T lymphocyte cells develop in the thymus. They are essential for fighting infections and preventing cancer. The thymus is located just above the heart. It is large in children and gradually reduces in size with age. In the ...

Scientists discover new process shaping red blood cell development

Red blood cells give us life. They ferry oxygen throughout our bodies. Breakdowns in red blood cell development can be life-threatening, but scientists still have much to learn about the molecular processes that ensure these ...

Transformer cells: Shaping cellular 'behaviour'

Scientists from Sechenov University, conjointly with their fellow Chinese and American researchers, have examined the latest advances in the use of skeletal muscle progenitor cells, specifying the core challenges inherent ...

HSPC 'seeds' reveal VCAM-1+ macrophage role in homing process

Hematopoietic stem and progenitor cells (HSPCs) give rise to all blood lineages that support life. HSPCs, like seeds, need a suitable microenvironment to maintain their function. A process called "homing" allows HSPCs to ...

The gene code of growing limbs

When a fetus develops, cell division and differentiation, gene expression, cell-to-cell signaling, and morphogenesis must be carefully coordinated to occur in the correct sequence and for the proper amount of time. Failures ...

Progenitor cell

Like stem cells, progenitor cells have a capacity to differentiate into a specific type of cell. In contrast to stem cells, however, they are already far more specific: they are pushed to differentiate into their "target" cell. The most important difference between stem cells and progenitor cells is that stem cells can replicate indefinitely, whereas progenitor cells can only divide a limited number of times. Controversy about the exact definition remains and the concept is still evolving.

Despite the difficulty of defining progenitors, the term is frequently used in research. Thus, the importance of progenitors cannot be ignored.

The terms "progenitor cell" and "stem cell" are sometimes equated.
