Blastogenesis

  • (15) To determine whether the polyclonal immunomodulator, Phytohemagglutinin (PHA), stimulates murine lymphocytes in vivo and causes cytotoxic differentiation, we studied blastogenesis and the concomitant synthesis of macromolecules (DNA, RNA and protein) by lymphocytes at different hours after injection of PHA in mice.
  • (16) Use of Toxocara exoantigens in the blastogenesis assay revealed that Toxocara exoantigens could elicit between 20 and 95% of the ConA response in BAL cells, while in spleen cells Toxocara exoantigens could only elicit 1 to 5% of the ConA response.
  • (17) The marked inhibition of periodic acid-induced blastogenesis, exerted by Fremy's salt and by bisulfite, was attributed to the effect of the corresponding carbonyl addition derivatives formed in situ of the oxidized cell membranes.
  • (18) Both deoxyadenosine and deoxyguanosine, when incubated separately with OKT4 and OKT8 cells in the presence of EHNA, an ADA inhibitor, did not significantly inhibit lymphocyte blastogenesis to a greater extent in ARC patients than in controls.
  • (19) In vitro lymphocyte blastogenesis has been useful in the diagnosis of nickel allergy in humans, but has not been applied to predictive testing in animals.
  • (20) Phytohemagglutinin-induced lymphocyte blastogenesis, however, was depressed by water-soluable adjuvants.

Undifferentiated


Definition:

  • (a.) Not differentiated; specifically (Biol.), homogenous, or nearly so; -- said especially of young or embryonic tissues which have not yet undergone differentiation (see Differentiation, 3), that is, which show no visible separation into their different structural parts.

Example Sentences:

  • (1) The subcellular distribution of sialyltransferase and its product of action, sialic acid, was investigated in the undifferentiated cells of the rat intestinal crypts and compared with the pattern observed in the differentiated cells present in the surface epithelium.

  • (5) All 51 undifferentiated NPCs contained significant numbers of EBV-genome copies per cell.
  • (6) Unfortunately, it does not contain a population of undifferentiated stem cells to supply the necessary healthy neurons.
  • (7) The anterior division can be further parcellated into dorsal, lateral, and ventral areas, and each of these areas, along with the posterior division, can be thought of as containing more-or-less discrete nuclei embedded within a relatively undifferentiated region.
  • (8) In undifferentiated glioblastomas, the reverse situation was observed, no SS receptors were found (0 of 14) but EGF receptors were present in a majority of tumors (8 of 14).
  • (9) The human epidermal growth factor receptor (hEGF-R) was introduced into murine P19 embryonal carcinoma (EC) cells, which do not express endogenous EGF-R. Undifferentiated stable P19 EC transfectants containing multiple copies of the hEGF-R complementary DNA were isolated.
  • (10) However, the tip cells are slow to differentiate, and hence immature fruiting bodies contain a small population of undifferentiated tip cells.
  • (11) We report on a patient with AL, which showed a very rapid switch from the lymphoblastic phenotype exhibited at presentation to a myelomonoblastic one, appeared at first relapse, and lastly progressed to an undifferentiated leukemia in the terminal phase.
  • (12) The pathologic diagnosis was rhabdomyosarcoma in 75% of cases, yolk sac tumor in 13% of cases, malignant mesenchymoma in two cases, clear cell carcinoma in two cases, and undifferentiated sarcoma in one case.

  • (20) Ultrastructurally, the tumor cells were composed principally of undifferentiated mesenchymal cells, and contained prominent pools of glycogen in the cytoplasm.
