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 …

Laparoscopic management of quadruplet heterotopic pregnancy after ovarian stimulation cycle

Introduction. We report a rare case of a heterotopic abdominal pregnancy with three intrauterine pregnancy, one with a viable fetus, treated successfully by laparoscopy. Methods. A 40-year-old patient with primary sterility, who un- derwent pharmacological ovulation induction, presented abdominal pain in the right iliac region. A trans-vaginal ultrasound showed an image suggestive of ectopic gestation near the right ovary, associated with three intrauterine gestational sacs with only one viable fetus. Basing on this observation, we performed an operative laparoscopy that confirmed the presence of a right ectopic abdominal pregnancy. Since the right ampullar tubal was ruptured and bleeding, …
