Abstract
BACKGROUND Total nucleated cell (TNC) count is the most important biological feature to consider in assessing the quality of umbilical cord blood (UCB) for hematopoietic stem cell (HSC) transplantation. Certain obstetric factors have been reported to increase TNC count in UCB units collected for transplantation. The aim of our study was to analyze how various maternal, neonatal and obstetric factors affected TNC count in the UCBs we collected for our cord blood bank in southern Italy. METHODS We performed a retrospective analysis of 634 medical records of UCBs collected by Calabria Cord Blood Bank (CCBB), Reggio Calabria, Italy, between January 1, 2010, and December 31, 2016. We analyzed various maternal, neonatal and obstetric variables factors and related this factor with the characteristic of TNC. RESULTS We found that the average number of TNCs was significantly greater in vaginal delivery than in caesarean delivery. We also found that TNCs were higher in the 40th week of pregnancy and when Apgar 1' scores were ≤9. The effect of a newborn's gender was less evident on TNC count. CONCLUSIONS Knowledge of factors predictive of a higher TNC count would help cord blood banks more efficiently identify donors likely to yield high-quality UCBs for transplantation.

Cell Tissue Bank 2020; 21:77-87.

Abstract
Blood banking is a long and complex process requiring an accurate screening of potential donors and high-quality control systems. Previous studies in literature investigated factors potentially determining a higher cell levels with the aim of optimizing donors' selection and improving banking process. This study aims to identify factors associated with the concentration of stem cells in umbilical cord blood, so increasing the probability of bankability, focusing on the possible implications in terms of obstetric and resources management. This is a retrospective study conducted in the Obstetric Units of two Italian Hospitals in Montebelluna and Castelfranco Veneto. Study has been conducted on cord blood units banked between 1999 and 2015. Data on medical histories and clinical characteristics of mother and baby have been retrieved via a retrospective examination of medical records. A total of 869 cord blood units were studied. At multivariable analysis, in agreement with literature, birthweight and placental weight have been found to be associated with higher concentration of total nucleated cells. As additional factor, amount of fluid infused was associated with cord blood units' count. This study is the first one to clearly identify the role of fluid infusion on cord blood units' counts in addition to placental weight and delivery. Some non-modifiable features can help in predicting bankability from pre-natal aspects to factors more related with obstetric management is suggested.

Associations among birth weight, placental weight, gestational period and product quality indicators of umbilical cord blood units. Transfus Apher Sci 2011; 46:39-45. [PMID: 22206793 DOI: 10.1016/j.transci.2011.10.031] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2011] [Revised: 08/17/2011] [Accepted: 10/19/2011] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Numbers of CD34+ cell and total nucleated cell (TNC) and cord blood volume are commonly used as indicators for haematopoietic potential of umbilical cord blood (UCB) units. The purpose of this study was to investigate the relationship between donor-related factors and the quality indicators of UCB. METHODS Obstetric and neonatal clinical laboratory data of a total of 1549 UCB units were obtained from Buddhist Tzu Chi Stem Cells Center (BTCSCC) Cord Blood Bank. A retrospective multivariate analysis was conducted to analyze the data. RESULTS Our results showed that birth weight had positive correlations with each of the clinical features of CD34+ cell number, TNC count and unit volume of UCB, followed by the placental weight. Longer gestational period would decrease CD34+ cell number and volume of UCB. Female baby and mode of vaginal delivery of neonates were found to have larger amount of TNC in UCB. CONCLUSION Our results would be helpful and beneficial in building up standard criteria for evaluating stored UCB units.

Abstract
Umbilical cord blood (UCB) has become an alternative source for providing haematopoietic stem/progenitor cells as well as non-haematopoietic stem cells, compared to the conventional sources of bone marrow (BM) and peripheral blood (PB). Although UCB has many advantages over BM and PB there are still limitations to its use in the clinical setting, principally cell numbers. Thus, this study aimed to characterise components that comprise UCB samples and the physiological factors that affect them: (i) gender, (ii) obstetric history, (iii) infant birth weight, (iv) gestation stage and (v) mother's age. Our results show that UCB total nucleated cell (TNC) and haematopoietic stem cell (CD45+/CD34+) content is significantly affected by the baby's birth weight, mother's age at delivery, mother's obstetric history, and gestational stage at due date, all with p values<0.0001. The only parameter not found to be significant was gender, although results did suggest that female infants provide greater stem cell numbers than their male counterparts. Other UCB cellular sub-types affected were T-cells, dendritic cells and B-cells. In conclusion, this study demonstrates that many different obstetric factors must be taken into account when processing and cryo-banking UCB units for transplantation.
