ABSTRACT
Transamniotic stem cell therapy (TRASCET) is an emerging strategy for prenatal stem cell therapy involving the least invasive method described to date of delivering select stem cells to virtually any anatomical site in the fetus, including the blood and bone marrow, as well as to fetal annexes, including the placenta. Such broad therapeutic potential derives, to a large extent, from unique routing patterns following stem cell delivery into the amniotic fluid, which have commonalities with naturally occurring fetal cell kinetics. First reported experimentally only less than a decade ago, TRASCET has yet to be attempted clinically, though a first clinical trial appears imminent. Despite significant experimental advances, much promise and perhaps excessive publicity, most cell-based therapies have yet to deliver meaningful large-scale impact to patient care. The few exceptions typically consist of therapies based on the amplification of the normal biological role played by the given cells in their natural environment. Therein lays much of the appeal of TRASCET, in that it, too, is in essence a magnification of naturally occurring processes in the distinctive environment of the maternal-fetal unit. As much as fetal stem cells possess unique characteristics compared with other stem cells, so does the fetus when compared with any other age group, converging into a scenario that enables therapeutic paradigms exclusive to prenatal life. This review summarizes the diversity of applications and biological responses associated with the TRASCET principle.
