The flt3 ligand (FL) is a growth factor for primitive hematopoietic cells. Serum levels of FL are inversely related to the number and proliferative capacity of early hematopoietic progenitors. We sought to elucidate the molecular mechanism underlying this regulation. Expression of FL was examined in peripheral blood (PB) and bone marrow (BM) cells under normal steady-state hematopoiesis and dur...

If targets are fl anked by congruent or incongruent distractors, performance is facilitated or impaired, respectively. Prior studies revealed that, with normal letters, this fl anker effect is more pronounced with leftthan with right-side fl ankers. The present study shows that the left-side bias is eliminated if the fl ankers (but not the target) are mirrored (Experiment 1). If the orientation...

This case series highlights the advantages in the use of three regional fl aps, submental fl ap, sternocleidomastoid fl ap and transverse cervical fl ap in maxillofacial primary defect reconstruction after ablative cancer surgery through presentation of three head and neck cancer patients in whom it was decided to do pedicled fl aps rather than free fl aps. Aim and objective: This article is do...

Follicular lymphoma (FL) grades 1 and 2 are regarded as a distinct disease entity, whereas data suggest that FL grade 3 might be an inhomogeneous tumor category. To define the biologic spectrum of FL, 89 follicular lymphomas were studied for their cytologic composition, antigen expression, mitotic and proliferation indices, cytogenetics, and clinical data. In contrast to the homogeneous appeara...

Neurospora crassa fluffy (fl) mutants are unable to produce macroconidia. We cloned the fl gene to determine its role in regulating conidiation. A cosmid clone containing fl was identified by complementation. The sequence of fl revealed that it encodes a Gal4p-type C6 zinc cluster protein with greatest similarity to the N. crassa NIT4 protein that regulates genes required for nitrate utilizatio...

A novel hematopoietic growth factor for primitive hematopoietic progenitor cells, the ligand for the flt3/flk2 receptor, (FL), has been recently purified and its gene has been cloned. In the present study, we investigated the effects of FL on the proliferation and differentiation of normal and leukemic myeloid progenitor cells. We demonstrate that FL is a potent stimulator of the in vitro growt...
