Evidence of alloreactive T lymphocytes in fetal liver: implications for fetal hematopoietic stem cell transplantation
The use of hematopoietic stem cells for in utero transplantation to create permanent hematochimerism represents a new concept in fetal therapy, although this approach has provided heterogeneous results. In this paper we have undertaken molecular, phenotypic and functional studies aimed at identifying the presence of fully competent T lymphocytes in samples of fetal livers and cord blood. We found mature VDJ TCR beta chain transcripts in fetal liver cells taken from 7 to 16 weeks of gestation and a similar pattern was detected in cord blood cells sampled from 13.5 to 20.5 weeks of gestation. A Vbeta8 gene sequence comparable to that detected in adult PBMC was found in fetal liver samples at …
In utero fetal liver hematopoietic stem cell transplantation: is there a role for alloreactive T lymphocytes?
The use of hematopoietic stem cells for in utero transplantation to create permanent hematochimerism represents a new concept in fetal therapy, although this approach has provided quite heterogeneous results. Flake and Zanjani have provided an excellent updated review of the current knowledge of in
