Thrombopoietin (TPO), the ligand for c-mpl, stimulates proliferation of committed megakaryocytic progenitors and induces maturation of megakaryocytes. To better understand factors regulating TPO levels, we measured blood levels of TPO in patients wit

This paper describes two approaches to measuring transmission losses in optical fibers by the thermal-rise technique. Rapid and convenient loss determinations can be made on short (~10-cm) lengths of fibers. Values of loss as low as ~10(-7) cm(-1) (0

A new technique for measuring the attenuation of light in clad fibers is discussed. The basic approach is to measure the temperature rise produced in the fiber by the absorption of the light. Calculations indicate that the theoretical limit of sensit

The goal of the present study was to assess the relative importance of receptor-bound and secreted plasminogen activator urokinase (u-PA) in generating cell-surface plasmin and fostering destruction of normal tissue by tumor cells. We first showed th

Objectives. Neonatal thrombocytopenia occurs commonly in neonatal intensive care units. The role of the thrombopoietin (Tpo) system in normal neonatal platelet regulation and neonatal thrombocytopenia is not well understood. The purpose of our study

Thrombopoietin (TPO), the primary regulator of megakaryocytopoiesis, also mediates biologic effects in vitro on hematopoietic cells more primitive than those committed to the megakaryocyte (MK) lineage. To assess the spectrum of hematopoietic effects

Binding of urokinase-type plasminogen activator (uPA) to its glycosylphosphatidylinositol-anchored receptor (uPAR) initiates signal transduction, adhesion, and migration in certain cell types. To determine whether some of these activities may be medi

To investigate the effect of thrombin on the urokinase plasminogen activator receptor (u-PAR) in retinal pigment epithelial (RPE) cells.The authors analyzed u-PAR mRNA by Northern blot hybridization. Retinal pigment epithelial cell surface u-PAR was
