Abstract

CONCEPT was advanced some 37 years ago, evidence for the existence of a humoral regulator of platelet production, first termed thrombopoietin (Tpo) by Kelemen et al,' accumulated very slowly.Initial studies in the 1960s and 1970s indicated that thrombocytopenia evokes characteristic marrow changes including increases in the number, size, ploidy, and maturation rate of megakaryocyte^.^"Platelet transfusion-induced thrombocytosis was associated with the opposite effects.*These findings were later confirmed with the availability of improved methods of assessing cellular DNA content and megakaryocyte maturation.'"'Ode11 et allz are generally acknowledged as providing the first description of a humoral substance in the sera of thrombocytopenic rats which induced thrombocytosis in recipient animals.Subsequent investigators have reported that thrombocytopenic serum also induces many of the marrow effects associated with thromb~cytopenia.'~"~However, significant progress in the field awaited the development of reliable, albeit cumbersome, assays of Tpo activity.I7-*' Attempts to biochemically purify Tpo from plasma, serum, urine, and conditioned culture medium from various cell lines occupied much effort during the 1 9 8 0 ~.~" ~~ Unfortunately, because of the complex nature of the starting material and difficulties associated with the use of an in vivo assay, these attempts failed to yield homogeneous protein adequate for protein sequencing and cDNA cloning, the official rite of passage for a hematopoietic growth factor.Furthermore, a number of cytokines were described in the late 1980s and early 1990s that possessed activity in various assays of megakaryocyte development.2943During the past several years, many investigators suggested that a distinct, lineage-specific thrombopoietin may not exist. THE SEARCH FOR TPOFour groups have published extensively on the purification of substances that either augment platelet production or stimulate megakaryocyte development.Levin's group has reported on the biologic effects of Tpo partially purified from thrombocytopenic rabbit plasma.24b27"*45These workers used ammonium sulfate fractionation, two types of lectin affinity chromatography, and gel filtration on high-pressure liquid chromatography (HPLC) columns to obtain material that reproducibly increased platelet production in recipient animals.Its reported molecular weight (M,) was 40 to 47 kD."Additional biologic activities ascribed to partially purified Tpo include augmentation of megakaryocyte ploidy, both in vitro Blood, Voi 86, No 2 (July 15).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
