Diagnosis of acute foetal distress does not preclude banking of umbilical cord blood units.

Clinical diagnosis of acute foetal distress (AFD) is based on several parameters such as abnormal foetal heart rate (FHR) pattern and/or meconium liquid staining (MLS). Standards for cord blood (CB) banking indicate that AFD should be considered as exclusion criteria for CB collection, but precise guidelines on how to proceed with CB collection in the presence of AFD signs during labour are not available. We evaluated whether the presence of FHR abnormality and/or MLS during labour 1) reduced the CB collection activity; 2) were associated with the infant's acidaemia or asphyxia and 3) deteriorated the biological characteristics of CB units.

Optimizing umbilical cord blood collection: impact of obstetric factors versus quality of cord blood units.

Introduction: The main limitation factor for wide use of umbilical cord blood units (UCBs) as a source of hematopoietic progenitors for transplantation is cell dose. International standard guidelines recommend 2 x 10(7)/kg as the minimal nucleated cell dose for UCB transplantation for adults and 3.7 x 10(7)/kg for children.

Evaluation of biological features of cord blood units collected with different methods after cesarean section.

Introduction: Cord blood banks are established worldwide as a result of the increased use of umbilical cord blood (UCB) transplantation. The outcomes of this procedure relate to the cell dose of the UCB unit and the UCB collection. The aim of this study was to evaluate whether the mode of collection influenced the biological features of the UCB units.

Placental/umbilical cord blood: experience of st. Eugenio Hospital collection center.

Background: Umbilical cord blood (UCB) contains stem cells and may be an alternative source to bone marrow and peripheral blood stem cells for allogeneic transplantation for the treatment of hematologic malignancies and genetic disorders. Many UCB banks have been established worldwide to quickly provide high quality materials for transplantation. Moreover, a detailed set of standards for cord blood banking have been drawn to guarantee the quality of the products.

Umbilical cord blood: the role of apoptosis in the control of CD34+ cell counts.

Background And Objective: Cord blood obtained at delivery can be used for hematopoietic precursor cells (HPC) transplantation. The major limit for its success is represented by the low cellular yield of the stem cell population. The objective of this study was to determine the role played by apoptosis in the numerical control of CD34+ cell counts.
