Stress factors and umbilical cord blood banking

Presence of meconium‐stained amniotic fluid in cesarean deliveries increases the total nucleated cell content of umbilical cord blood units

“…Similar results were observed for CD34+ cells, probably due to the method variability. We observed the same results for vaginal deliveries in a previous study 3 . In the group of meconium‐stained cesarean deliveries, gestational age was longer and newborn weight was higher.…”

“…They included in the study only 11 emergency cesarean deliveries. Our group has previously shown that for vaginal deliveries, UCB from meconium‐stained amniotic fluid (presence of meconium in amniotic fluid) deliveries contains more TNC and CD34+ cells 3,4 …”

Influence on Time to Cryopreservation in Umbilical Cord Blood Units

“…The arrival to the bank out of the working time may explain the delay in the processing of more distant units. The role of variables related with the mother, the baby, the labor or the pregnancy in UCB parameters has been investigated, but there is some controversy about the influence of these variables in the final quality of the unit [16,19,20,21] and in our series none of the recorded variables of this type was significantly related with the viability or the CD34+ cells.…”

Factors influencing the success of cord blood collection: a tertiary perinatal medicine center’s experience

“…Nonetheless, determination of donor eligibility is crucial, especially for low-income countries with limited resources. Unit volume, total nucleated cell (TNC) count, number of CD34+ HSCs, infant birth weight, gestational age at birth, fetal distress, placental weight, previous live births, meconium-stained amniotic fluid, mode of delivery, and collection technique can affect the quality and eligibility of CBUs for storage (11)(12)(13)(14)(15)(16)(17)(18)(19)(20).…”
