Human Platelet Lysate (HPL)

HPL is frequently requested from Blood Centers either as outdated platelet concentrates or more elaborate products. A review written by members of the WP is available here.

We currently work on the questions of dosing, use of fresh vs outdated platelets, storage conditions and quality control sources or platelets. We encourage exchange between groups and support contacts.

Autologous Serum Eye drops

Literature co-authored by Members of the Working Group is available here:

The group of Denese Marks in the Australian Red Cross Blood Service, Sydney has published a review which is recommended to read. 

Pieter van der Meer and colleagues from Sanquin Blood Supply, The Netherlands also published a review in 2016 on SED.

Extracellular vesicles

Extracellular vesicles are secreted by almost all cell types. These small carriers are found in all body fluids and are considered to be key components in cell-cell communication. A recent review with contribution form the Working Party can be found here:

Unproven Cellular Therapies

We consider this as an important topic that transfusionsists should be aware of and have an attitude to. The International Society of Cellular Therapies (ISCT) has published a manuscript containing recommendations which we support (DOI: 10.1016/j.jcyt.2015.10.007).

Biobanking for Therapeutic Purposes

The WP is currently working on defining approaches towards Biobanking, and collecting references for currenty regulatory standards.
