What's the difference between progenitor and progenitress?
Progenitor
Definition:
(n.) An ancestor in the direct line; a forefather.
Example Sentences:
(1) The effects of in vivo administration of native prostaglandin E2 (PGE) on the cycling status of the granulocyte-monocyte progenitor cell (CFU-GM) were examined in a mouse model.
(2) In healthy persons the supernatant of lymphocytes preincubated with PHA and ALG was found to show a stimulating effect to clonogenic properties of marrow progenitors, the mentioned effect being not in proportion to the concentration value.
(3) We therefore think that the detailed examination of CALLA(-) non-T non-B ALL cells using myeloid specific antibodies is helpful in clarifying the characteristics of myeloid precursors and the common bipotential stem cell of lymphoid and myeloid progenitors.
(4) The high levels of circulating progenitor cells in ALL and CLL patients clearly distinguish them from other cytopenic hematological malignancies, in which decreased progenitor cell levels have been demonstrated previously (acute myeloid leukemia, hairy cell leukemia).
(5) Studies on proliferation and differentiation of granulocyte-monocyte progenitor cells in Chediak-Higashi syndrome (CHS) were done on a 1-month-old patient, using the soft-agar bone marrow culture technique.
(6) Certain mouse and human hematopoietic progenitor cells also contain an aldehyde dehydrogenase that catalyzes the detoxification of aldophosphamide, but the specific identity of this enzyme remains to be established.
(7) Mouse spleen cells rich in erythroid progenitors were washed free of endogenous Epo and then incubated in the absence of Epo.
(8) The bone marrow differentials and numbers of granulocyte-macrophage progenitors (CFC-GM) were determined after irradiation with 1.5 Gy.
(9) However, the studies on 0-2A progenitor cells were carried out in bulk cultures of optic nerve, and so it was possible that other cell-cell interactions were required for differentiation in culture.
(10) In culture, GY30 cells sustain the production of granulocyte-macrophage progenitor cells (GM-CFU) but fail to support the survival of pluripotential stem cells (CFU-S).
(11) The development of T cells from stem (progenitor) cells to effector cells results from a two-wave process of proliferation and differentiation.
(12) No chemical or immunological differences were observed in the cell wall carbohydrate of the noncapsulated streptococcus, 89R50, and that of its capsulated progenitor.
(13) This is exemplified in lymphoma cells (chronic lymphocytic leukemia of B or T type, Sezary Syndrome, immunocytoma) that resemble mature and immunocompetent T and B cells, in T cell acute lymphoblastic leukemia (T-ALL) (equivalent to thymus cells) and in non-T ALL (corresponding to lymphoid progenitor cells in the bone marrow).
(14) We studied MDS-associated inhibitory activity, which inhibited colony formation in vitro of granulocyte-macrophage progenitors (CFU-GM).
(15) In contrast, populations containing BFUe yielded a striking (sixfold for CFUe; 23-fold for e-clusters) expansion of late progenitors in the presence of Epo.
(16) The stem cell loss immediately following 55Fe injection is in our interpretation caused by rapid differentiation along the erythroid pathway in a response that involves all progenitor populations.
(17) We report here that human IL-6 and IL-3 act synergistically in support of the proliferation of progenitors for human blast cell colonies and that IL-1 alpha reveals no synergism with IL-3 when tested against purified human marrow progenitors.
(18) In addition, we have examined the ability of these fibroblasts and their conditioned medium (CM) to induce differentiation of human hemopoietic progenitor cells.
(19) AF and its deacetylated form inhibited the development of macrophage and granulocytic colonies from progenitor cells in human bone marrow even at concentrations less than or equal to 10(-9)M. 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.
