Traditionally, it is understood that dizygotic (DZ) twins always have a dichorionic placenta.
However, with 8% blood chimerism in DZ twins, placental sharing is probably more common …

Chimerism occurs when an organism contains cells derived from more than one distinct
zygote. We focus on monochorionic dizygotic twin blood chimerism, and particularly twin …

In humans, naturally acquired microchimerism has been observed in many tissues and
organs. Fetal microchimerism, however, has not been investigated in the human brain …

Background Systemic sclerosis remains an orphan life-threatening autoimmune disease.
The unique immunomodulatory, proangiogenic, and antifibrotic properties of mesenchymal …

Rheumatic diseases affect a wide range of individuals of all ages, but the most common
diseases occur more frequently in women than in men, at ratios of up to ten women to one …

BACKGROUND: Detection of Y chromosome, thought to originate from previous
pregnancies with a male fetus, is common in women. Lower concentrations have been …

Microchimerism represents a condition where one individual harbors genetically distinct cell
populations, and the chimeric population constitutes< 1% of the total number of cells. The …

Among reported advantages of umbilical cord blood (CB) in transplantation is lower
leukemia relapse probability. Underlying cellular mechanisms of graft-vs.-leukemia (GVL) …

Communication via biological mediators between mother and fetus are key to reproductive
success and offspring's future health. The repertoire of mediators coding signals between …

Microchimerism, the coexistence of genetically disparate populations of cells in a receptive
host, is well described in both clinical and physiological settings, including transplantation …
