The expression of TF and other pro- and anticoagulant genes was analyzed in xeno- and serum-free manufactured MSCs. Furthermore, culture factors affecting its expression in MSCs were investigated. Finally, coagulation tests of fibrinogen, D-dimer, aPPTs, PTs, and TTs were measured in patient se...
Neuropeptides specifically bind to and modulate the function of lymphocytes. Substance P promotes T-lymphocyte endothelial cell adhesion by preferentially up-regulating lymphocyte function–associated antigen-1 and intercellular adhesion molecule-1 interactions.74 In human T lymphocytes, SP and its C-termina...
