Progenitor


Definition:

  • (n.) An ancestor in the direct line; a forefather.

The disease suppressive activity of AF could result in part from the reduction of cell numbers in arthritic lesions and our findings provide a mechanism for this possibility.
  • (20) Spontaneously hypertensive rats (SH) with an increased number of red blood cells (RBC), microcytosis, and normal hemoglobin (Hb) concentration were used to study the effect of different manipulations of the erythron on erythropoietin production and on erythroid progenitor proliferation by bone marrow cells in order to gain insight regarding the regulation of erythropoiesis.

Species


Definition:

  • (n.) Visible or sensible presentation; appearance; a sensible percept received by the imagination; an image.
  • (n.) A group of individuals agreeing in common attributes, and designated by a common name; a conception subordinated to another conception, called a genus, or generic conception, from which it differs in containing or comprehending more attributes, and extending to fewer individuals. Thus, man is a species, under animal as a genus; and man, in its turn, may be regarded as a genus with respect to European, American, or the like, as species.
  • (n.) In science, a more or less permanent group of existing things or beings, associated according to attributes, or properties determined by scientific observation.
  • (n.) A sort; a kind; a variety; as, a species of low cunning; a species of generosity; a species of cloth.
  • (n.) Coin, or coined silver, gold, ot other metal, used as a circulating medium; specie.
  • (n.) A public spectacle or exhibition.
  • (n.) A component part of compound medicine; a simple.
  • (n.) An officinal mixture or compound powder of any kind; esp., one used for making an aromatic tea or tisane; a tea mixture.
  • (n.) The form or shape given to materials; fashion or shape; form; figure.
