Immunodeficiency after hematopoietic stem cell transplantation leads to a high risk of opportunistic infections. We evaluated B-lymphocyte reconstitution in 36 children by heavy chain third complementarity determining region (CDR3)-fingerprinting and immunophenotypic analysis. The time necessary to return to the normal immunoglobulin heavy chain-CDR3 polyclonal situation was basically related to the type of transplant and this process did not recapitulate fetal ontogenesis.
