THE HISTOGENESIS OF BLOOD PLATELETS [PDF]
1. Under normal circumstances blood platelets are largely derived from the megakaryocyte of the blood-forming organs. 2. The transitional leucocyte, representing a persistent form of the embryonic premegakaryocyte, is a circulating homologue of the megakaryocyte and probably plays some part in normal platelet formation. 3.

Platelet Function in Platelet Concentrates and in Whole Blood [PDF]
Platelet function was studied in CPD whole blood stored at 4°C for one and three days and in platelet concentrates stored at room temperature for the same periods of time. Comparisons were made of platelet shape, nucleotide content, β-thromboglobulin (βTG) liberated during storage, and platelet aggregation in response to ADP, collagen, sodium ...

Circulating histones as clinical biomarkers in critically ill conditions
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

CLEC-2 and Syk in the megakaryocytic/platelet lineage are essential for development [PDF]
The C-type lectin receptor CLEC-2 signals through a pathway that is critically dependent on the tyrosine kinase Syk. We show that homozygous loss of either protein results in defects in brain vascular and lymphatic development, lung inflation and ...

Binding of adenosine diphosphate to human blood platelets and to isolated blood platelet membranes [PDF]
The equilibrium binding of 14C-labeled ADP to intact washed human blood platelets and to platelet membranes was investigated. With both intact platelets and platelet membranes a similar concentration dependence curve was found. It consisted of a curvilinear part below 20 microM and a rectilinear part above this concentration. At high ADP concentrations,

Subpar reporting of pre‐analytical variables in RNA‐focused blood plasma studies
Pre‐analytical variables strongly influence the analysis of extracellular RNA (cell‐free RNA; exRNA) derived from blood plasma. Their reporting is essential to allow interpretation and replication of results. By evaluating 200 exRNA studies, we pinpoint a lack of reporting pre‐analytical variables associated with blood collection, plasma preparation ...

The actin binding proteins cortactin and HS1 are dispensable for platelet actin nodule and megakaryocyte podosome formation [PDF]
A dynamic, properly organised actin cytoskeleton is critical for the production and haemostatic function of platelets. The Wiskott Aldrich Syndrome protein (WASp) and Actin-Related Proteins 2 & 3 Complex (Arp2/3 complex) are critical mediators of ...

Ulcerative colitis (<i>colitis ulcerosa</i>) is a non-specific inflammatory bowel disease of unknown etiology. The symptoms which are observed in the course of ulcerative colitis are: an increase in the number of leukocytes and blood ...

Cancer‐associated fibroblasts (CAFs) promote cancer growth, invasion (metastasis), and drug resistance. Here, we identified functional and diverse circulating CAFs (cCAFs) in patients with metastatic prostate cancer (mPCa). cCAFs were found in higher numbers and were functional and diverse in mPCa patients versus healthy individuals, suggesting their ...
