21. Immunomodulation during human pregnancy : placental exosomes as vehicles of immune suppression
Sammanfattning : The mammalian pregnancy comprises a challenge to the maternal immune system since the fetus is semi-allogeneic and could thus be rejected. Pregnancy success is associated with the placenta that is not only essential for oxygen supply, nourishment and pregnancy hormones but also plays a role in the protection of the fetus against maternal immunologic attack.

22. Fetal hematopoietic cells in early gestation : aspects in view of fetal transplantation
Sammanfattning : The fetus as a patient is a challenge. There are opportunities for early, sometimes life-saving procedures or there may be advantages in prenatal rather than postnatal intervention. This is the case in fetal hematopoietic cell (FHC) transplantation where conditions caused by a defect in blood cell formation may be life-threatening to the fetus. LÄS MER
23. Experimental studies of human fetal liver cells : in regard to in utero hematopoietic stem cell transplantation
Sammanfattning : Successful in utero hematopoietic stem cell transplantation represents a potential step forward in the management of patients with severe inherited hematological, metabolic and immunological disorders. Animal data from a number of species have demonstrated evidence of engraftment, but to date the only effective in utero transplantations (IUTx) in humans have been performed in fetuses with severe immunodeficiencies, suggesting that the fetal immune system play a vital role in the success or failure of in utero transplantation.

24. Pre- and perinatal factors in long-term development : behavioral and intellectual performance for boys and girls at school age as related to birth weight and gestational age, with special regard to maternal hormone levels and smoking during pregnancy
Sammanfattning : The aim of the present work was to investigate long-term intellectual and behavioral development in relation to pre- and perinatal factors, with emphasis on birth weight and gestational age, for boys and girls at school age. The first part of the work consists of a short-term longitudinal clinical study of pregnant women in risk pregnancies. LÄS MER
25. Antibodies during pregnancy : Aspects on complications during pregnancy and complications related to transfusion
Sammanfattning : The fetus acquires half of its genetic infonnation from the father and represents a foreign graft in pregnancy. The overall mechanisms contributing to immunologic tolerance and successful pregancy still are an enigma. Accumulating results of immunologic research, however, offer an explanation for many events in pregnancy. LÄS MER
