Recounting the advancement of platelet concentrates

Comparative Study of Four Platelet-Rich Plasma Methods for Preparing Platelet Concentrates

Background: Platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. Platelet concentrates can be prepared by the apheresis method or from the whole blood using the Buffy-coat or Platelet-rich plasma methods. The purpose of this study was to compare four variations of platelet-rich plasma method based on double...

Evaluation of microRNAs; mir223, mir222 and mir92a levels in the Platelet-derived microparticles in the Platelet concentrates produced by Platelet Rich Plasma method during storage

Abstract Background and Objectives Platelets release microparticles containing cellular components, including microRNAs, during storage. Assessment of these microRNAs is one of the markers for evaluation of platelet storage lesions. The aim of the present study was to evaluate the level of changes in the expression of mir-223, mir-92a and mir-222 during storage in platelets prepared by platele...

Buffy-coat-derived pooled platelet concentrates and apheresis platelet concentrates: which product type should be preferred?

There is an ongoing debate whether platelet concentrates (PCs) prepared from either whole-blood donations or by plateletpheresis are superior. Usage of these two product types varies greatly between countries and individual institutions. Some use mainly apheresis PCs; others prefer pooled PCs which are produced from whole-blood donations. This review summarizes the existing information on these...

Laboratory analyses for evaluation of platelet disorders and platelet concentrates

Comparison of platelet counting technologies in equine platelet concentrates.

OBJECTIVE (1) To compare the performance of 4 platelet counting technologies in equine platelet concentrates and (2) to evaluate the ability of the Magellan platelet rich plasma (PRP) system to concentrate equine platelets. STUDY DESIGN Experimental study to assess method agreement. ANIMALS Adult mixed breed horses (n = 32). METHODS Acid citrate dextrose-A anti-coagulated whole blood was ...
