Abstrakt: Immunophenotype of mobilized stem blood cells (CD34+) was studied in 29 patients with late post-traumatic spinal lesions. The CD34+ cells demonstrated different levels of expression of CD45, CD38, monomorphic determinants HLA-DR and gp130 epitopes. Most patients presented with a CD34+ cell fraction with no or low expression of common leukocytic antigen CD45. Only 2 patients had greater than 15 percent of HLA-DR-CD38- cells in the CD34+ fraction. A common transducer molecule of interleukin-6 family cytokines gp130 was expressed on stem (CD34+) cells in all the cases, 26 percent of the patients had an activated gp130 phenotype, i.e. a combination of C7+ and A1- epitopes.
