Hematopoietic thymocyte precursors: II. Properties of the precursors
The properties of hematopoietic cells which serve as the precursors of cortical thymocytes in irradiated reconstituted mice have been described. These cells have been termed "prothymocytes." They are 10- to 15-mum diameter cells of low buoyant density. They are nonadherent to glass wool and more resistant to the lytic effects of steroids and gamma-irradiation than their progeny. They lack detec...
متن کاملHematopoietic thymocyte precursors: IV. Enrichment of the precursors and evidence for heterogeneity
A method has been developed for the enrichment of the hematopoietic precursors of thymocytes from spleen and bone marrow cells. Up to 40-fold enrichments were obtained resulting in preparations in which as few as 10(5) cells produced prompt repopulation of the thymus of an irradiated mouse. Precursor cells from bone marrow appear to contain the enzyme terminal deoxyribonucleotidyl transferase (...
متن کاملHematopoietic thymocyte precursors. I. Assay and kinetics of the appearance of progeny
A quantitative assay for the hematopoietic precursor of thymocytes has been developed. Using this assay the kinetics of appearance of the progeny of transfused bone marrow and spleen cells in the thymus of irradiated (760 R) mice has been studied. Precursor cells are seven to eightfold more common in bone marrow than in spleen and are absent from peripheral lymph nodes. They decline in number a...

Bcl-2 and bcl-xL function as suppressors of programmed cell death. The expression of bcl-2 protein in vivo is associated with long-lived hematopoietic cells such as mature lymphocytes and early myeloid progenitors. Bcl-xL, a homologue of bcl-2, is also expressed in lymphocytes and thymocytes. In contrast, the bcl-2-related proteins (bax, bad, and bak) act by promoting apoptotic cell death as sh...
متن کاملPreattentive Precursors to Phenomenal Properties
What are the relations between preattentive feature-placing and states of perceptual awareness? For the purposes of this paper, states of "perceptual awareness" are confined to the simplest possible exemplars: states in which one is aware of some aspect of the appearance of something one perceives. Subjective contours are used as an example. Early visual processing seems to employ independent, ...
