Senescent


Definition:

  • (a.) Growing old; decaying with the lapse of time.

  • (20) Our data suggest that the release of u-PA antigen by human macrovascular endothelial cells can be used as an indicator of cell senescence.

Seniority


Definition:

  • (n.) The quality or state of being senior.

Example Sentences:
