Omidubicel (nicotinamide-expanded cord blood) is a potential alternative source for allogeneic hematopoietic cell transplantation (HCT) when an HLA-identical donor is lacking. A phase I/II trial with standalone omidubicel HCT showed rapid and robust neutrophil and platelet engraftment. In this study, we evaluated the immune reconstitution (IR) of patients receiving omidubicel grafts during the first 6 months post-transplant, as IR is critical for favorable outcomes of the procedure.

Iron plays a central role in the pathogenesis of the two main features of HA: synovitis and cartilage destruction. The aim of this study was to investigate the synovial presence of the iron regulator proteins ferroportin (FPN), hepcidin, haemoglobin scavenger receptor CD163 (CD163), feline leukaemia virus subgroup C (FLVCR), and heme carrier protein 1 (HCP-1).

Coagulation proteases, such as FVIIa, the binary TF-FVIIa complex, free FXa, the ternary TF-FVIIa-FXa complex and thrombin, are able to stimulate PARs. Whereas the role of PARs on platelets is well known, their function in naïve monocytes and peripheral blood mononuclear cells (PBMCs) is largely unknown.

The aim of the present study was to evaluate whether cartilage damage can still be averted by addition of IL-4 plus IL-10 when added after the onset of a bleed and whether aspiration of blood prior to addition of IL-4 plus IL-10 is of additive protective value.
Methods: Healthy canine hip and human shoulder cartilage was exposed to whole blood for 4 days.
