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.

Abstract
Today cord blood (CB) is a valuable source of hematopoietic stem cells to treat many hematological disorders. One of the limitations of CB utilization is the reduced number of nucleated cells including stem cells. Therefore, CB banks around the world have developed strategies in an attempt to improve donor selection and the quality of the CB inventory. This study aimed to determine the impact of passive smoking and caffeine consumption on CB quality. CBs were obtained from mothers who gave birth at King Abdulaziz Medical City. All mothers gave their informed consent. Personal interviews about the mother's demographics, smoking status and exposure, and caffeine consumption executed, followed by a chart review to analyze maternal and neonatal factors. Laboratory testing was performed on all collected CB units. Using descriptive statistics, maternal and newborn factors were analyzed. T-test or Mann-Whitney U Test, as appropriate, for continuous variables analysis to study the effect of second hand smoking and coffee consumption for the primary outcome. Our study demonstrated a reduction in CB MNC, including lymphocytes, in caffeine consumers among pregnant donors, as well as a reduction in cell potency activities, including total CFU and BFU-E. The effect of passive cigarette smoking on the same cohort was insignificant. Outcome of this study will help in optimizing the quality and quantity of stem cell harvesting from CB to get the maximum benefit and such knowledge will raise the awareness among pregnant women.

Abstract
Umbilical cord blood (UCB) is a rich source of hematopoietic cells that can be used to replace bone marrow components. Many blood disorders and systemic illnesses are increasingly being treated with stem cells as regenerative medical therapy. Presently, collected blood has been stored in either public or private banks for allogenic or autologous transplantation. Using a specific keyword, we used the English language to search for relevant articles in SCOPUS and PubMed databases over time frame. According to our review, Asian countries are increasingly using UCB preservation for future use as regenerative medicine, and existing studies indicate that this trend will continue. This recent literature review explains the methodology of UCB collection, banking, and cryopreservation for future clinical use. Between 2010 and 2022, 10,054 UCB stem cell samples were effectively cryopreserved. Furthermore, we have discussed using Mesenchymal Stem Cells (MSCs) as transplant medicine, and its clinical applications. It is essential for healthcare personnel, particularly those working in labor rooms, to comprehend the protocols for collecting, transporting, and storing UCB. This review aims to provide a glimpse of the details about the UCB collection and banking processes, its benefits, and the use of UCB-derived stem cells in clinical practice, as well as the ethical concerns associated with UCB, all of which are important for healthcare professionals, particularly those working in maternity wards; namely, the obstetrician, neonatologist, and anyone involved in perinatal care. This article also highlights the practical and ethical concerns associated with private UCB banks, and the existence of public banks. UCB may continue to grow to assist healthcare teams worldwide in treating various metabolic, hematological, and immunodeficiency disorders.

Abstract
Cord blood (CB) collected at birth has become a valuable stem cell source for hematopoietic stem cell transplantation (HSCT). However, the collection of umbilical cord blood always bears a risk of microbiological contamination, both in vaginal birth and in cesarean section. A total of 10 054 umbilical cord stem cell samples were successfully cryopreserved between 2010 and 2020, of which 783 (8%) samples were tested positive for bacterial contamination. Umbilical CB with a volume of less than 60 mL showed a bacterial contamination rate of 12%, and above 60 mL volume a rate of 6% was found demonstrating an inverse relationship between sample volume and contamination rate (correlation coefficient r = −0.9). The contamination rate was associated with the mode of delivery and showed a significantly higher contamination rate of 9.7% when compared with cesarean deliveries (1.4%). The 10-year period consistently shows an average contamination rate between 4% and 6% per year. It is conceivable that the inverse relationship between volume and contamination rate might be related to thinner veins although no scientific evidence has been provided so far. The lower contamination rate in cesarean sections appears to be related to the sterile operating setting. Overall, the rate of bacterial contamination varies and depends on the type of birth, the way of delivery, and probably the experience of the staff.

Abstract
Background The achievement of optimal number of CD34+ umbilical cord stem cells is essential for successful umbilical cord stem cell transplantation. So the aim of this study was to assess the potential effect of both maternal and neonatal factors on the umbilical cord blood CD34+ cell count. Methods The study was done on umbilical cord blood samples obtained from 20 mothers during labor. Their ages ranged from 22 to 34 years and were subjected to history taking, physical examination of the baby and assessment of the CD34+ cells count in umbilical cord blood. Results Number of previous live births and weight of the baby had a significant effect on CD34+ cells count while the sex of the baby, delivery route, maternal age and gestation period had no significant effect on CD34+ cells count. Conclusions Umbilical cord blood-derived CD34+ cell count is better with good weight and first babies and decreased with subsequent babies.

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.

Abstract
Background: Umbilical cord blood (UCB) is a rich source of hematopoietic stem cells and is useful for the treatment of blood diseases. The cost of UCB storage is high; thus, it is necessary to evaluate the quality of UCB before collection and cryopreservation. Aim: This study aimed to determine the maternal and neonatal factors that influence UCB before selection for cryopreservation. Materials and Methods: The analysis included 403 processed UCB units. The effects of maternal characteristics including maternal age and delivery method and neonatal factors such as birth weight, gestation duration, and sex on UCB quality were determined based on the collected blood volume, total nucleated cell (TNC) count, and CD34+ cell count. Results: The neonatal birth weight influenced the collected blood volume, TNC count, and CD34+ cell count. Neonates with higher birth weights produced better quality UCB units because of increased collected blood volumes, TNC counts, and CD34+ cell counts. However, an increase in the gestational age from 35 to 41 weeks led to decreases in the collected blood volume and CD34+ cell count. Conclusion: These data may be useful for determining the optimal cord blood units for collection and cryopreservation and for advising pregnant women using private banking services.

Abstract
Umbilical cord blood (UCB) is an attractive source of hematopoietic stem cells for transplantation in some blood disorders. One of the major factors that influence on transplantation fate is cord blood (CB) cell count, in addition to human leukocyte antigen similarity and CD34+ cell number. Here, we review the factors that could effect on quality and quantity of CBUs. Relevant English-language literatures were searched and retrieved from PubMed using the terms: CB, quality, collection, and transplantation. The numbers of total nucleated cells (TNCs) and CD34+ cells are good indicators of CB quality because they have been associated with engraftment; thereby, whatever the TNCs in a CB unit (CBU) are higher, more likely they led to successful engraftment. Many factors influence the quantity and quality of UCB units that collect after delivery. Some parameters are not in our hands, such as maternal and infant factors, and hence, we cannot change these. However, some other factors are in our authority, such as mode of collection, type and amount of anticoagulant, and time and temperature during collection to postthaw CBUs and freeze-and-thaw procedures. By optimizing the CB collection, we can improve the quantity and quality of UCB for storage and increase the likelihood of its use for transplantation.

Abstract
BACKGROUND Umbilical cord blood unit (CBU) volume is a predictor of its later clinical utility. Many studies suggest the need to increase the volume of CBU collected, but most obstetrical providers receive no formal collection training. STUDY DESIGN AND METHODS We designed and implemented an educational curriculum for obstetrics residents aimed at improving collection methods and increasing CBU volumes (CBUV). Residents were required to attend grand rounds and interactive didactic sessions on CBU collection followed by work with a simulated collection kit and then performed training collections under observation by a trained collector. Residents completed a self-assessment after each collection and received immediate personal feedback. Outside providers (non-UAMS physicians) received written instructional materials with the collection kits and had access to online training materials. They received feedback regarding their collection via standard mail. CBU donated to Cord Blood Bank of Arkansas for public use from 2014-2016 were analyzed. CBUV from residents were compared to those from outside providers. RESULTS After adjusting for maternal age and race, infant gender, gestational age, and birth weight, the least-squared mean CBUV was 92.1 mL for UAMS collections and 65.5 mL for outside provider collections. The improved CBUV of UAMS providers is statistically significant (p < 0.0001). CONCLUSION Our educational intervention was successful, and we believe that it can be replicated in other obstetrical residency programs. Cord blood collection education involving hands-on training with a model and immediate feedback improves CBUV, decreases kit waste, increases likelihood of CBU storage, and, therefore, inventory for transplantation.

Abstract
BACKGROUND Human umbilical cord blood has proven to be a successful alternate source of hematopoietic stem cells for pediatric patients with major hematologic disorders. Toxoplasma gondii is a global opportunistic protozoan which cause fatal complications in immunocompromised individuals. AIM Our goal is to study the prevalence of toxoplasmosis in umbilical cord blood (UCB) and to assess the sensitivity of ELISA and PCR for Toxoplasma infection screening. MATERIAL AND METHODS One hundred cord blood samples were collected immediately after delivery. Anti-Toxoplasma IgG and IgM antibodies were determined using ELISA method; Toxoplasma DNA was detected using nested PCR technique. Total nucleated cells (TNC) and HB were also determined. Demographic data and risk factors data related to the transmission of toxoplasmosis, were collected from mothers. RESULTS Among 100 cord blood samples, 36 (36%) were positive for anti-Toxoplasma IgG antibodies and 6 (6%) were positive for anti-Toxoplasma IgM antibodies. The nested PCR showed 11 (11%) samples containing Toxoplasma DNA from which, 6 (55%) samples were IgM positive. There was no significant association between the risk of Toxoplasma transmission and cord blood positivity for toxoplasmosis. CONCLUSION Owing to the prevalence of toxoplasmosis, its rapid progression and its fatal outcome in immunocompromised patients, cord blood screening for toxoplasmosis with nested PCR should be incorporated into cord blood bank screening protocols.

To determine which assay was useful for predicting the successful outcome of CB transplantation, CBs were grouped according to the temperature (4 °C, 24 °C, and 37 °C) and time (24, 48, and 72 h) after collection. The viability, early apoptosis, and colony forming units (CFUs) were ascertained for the total nucleated cells (TNCs) and CD34+ cells; in addition, the engraftment of infused CD34+ cells in NSG mice was determined. The viability of the TNCs and CD34+ cells and total CFUs were significantly decreased whereas the early apoptosis was significantly increased in the 72 h group at 37 °C compared to that of the 24 h group at 24 °C. The viability and early apoptosis of the TNCs correlated with those of CD34+ cells. In addition, the viability and early apoptosis correlated with the number of granulocyte/monocyte progenitor CFUs. In transplanted NSG mice, the frequency of human CD45+ cells decreased in the 72 h group at 24 °C compared to that of the 24 h group at 24 °C and was negatively correlated with early apoptosis of TNCs and CD34+ cells. This study demonstrated that the early apoptosis of TNCs and CD34+ cells constitutes a useful marker for predicting the engraftment of HSCs and may provide helpful data for standard assessment regarding CB quality by analyzing the correlation between in vitro and in vivo assays using NSG mice.

[PMID: 30537299 DOI: 10.1111/trf.15080] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Revised: 09/15/2018] [Accepted: 10/22/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Umbilical cord blood (UCB) has become an important source of transplantable CD34+ hematopoietic progenitor cells. Cord blood banks (CBBs) can increase their efficiency by minimizing the processing of UCB units with low CD34+ content, which have a lower likelihood of transplant utilization. We sought to identify a readily available preprocessing metric that would correlate with CD34+ cell counts, without the cost of additional analysis. STUDY DESIGN AND METHODS Data were compiled for 131 UCB units processed at the regional CBB. Preprocessing hematologic metrics, including complete blood count and differential, were compared to postprocessing CD34+ cell quantities. The data were divided into six groups of varying preprocessing metrics, then compared for significant differences in postprocessing CD34+ cell quantities to develop a screening guidance. RESULTS UCB units with nucleated RBC (nRBC) content of 15% or greater were found to have a significant increase in CD34+ cell percentage (p < 0.00001) and total CD34+ cell content (p < 0.0001). Units with preprocessing total nucleated cell count (TNC) of ≥ 1.50 × 109 with nRBC content of 15% or greater, and for TNC ≥ of 2.00 × 109 with nRBC content less than15%, had a significant increase in CD34+ content (p < 0.05 and p < 0.001, respectively). Applied as a screening guideline, these units had an increase in mean CD34+ content from 6.24 × 106 to 9.27 × 106 . Units originally in the bottom and top quartiles of CD34+ content constitute 5% and 53% of processed units meeting these TNC/nRBC criteria, respectively. CONCLUSION These screening criteria utilizing nRBC provides a guideline that public CBBs may use to increase their efficiency by minimizing the processing of UCB units with lower CD34+ cell content.

Abstract
OBJECTIVES There is a correlation between the success of the cord blood transplant and the numbers of HSC found in the unit of cord blood donation. The purpose of this analysis is to identify obstetric factors that may influence the quality of a cord blood unit taken during delivery. METHODS A retrospective study was carried out at the Liège cord blood bank on a sample of 7.463 cord blood units collected between 2000 and 2016. Eight obstetric factors were analyzed in relation to two dependent variables; the total nucleated cells (TNC) and the volume of one unit of cord blood. The Welch test, the percentiles 25 and 75 and the non-parametric Mann-Whitney Wilcoxon test were used. RESULTS Several obstetric parameters were found to influence (P<0.05) the quality of the cord blood unit are: cord clamping (>15 seconds), the use of oxytocin during labor, a more advanced gestational age (38-41 weeks), a higher birth weight (>3300 gr), and a higher weight of the placenta (>500 gr). A female newborn and the use of epidural, influence (P<0.05) the number of TNC but not the volume of the cord blood unit. CONCLUSION We can conclude that the birth weight, the weight of the placenta, the gestational age and cord clamping are parameters that could be used by maternity hospitals to identify births that enable more voluminous grafts which are richer in total nucleated cells.

Abstract
After 30 years of hematopoietic stem cell use for various indications, umbilical cord blood is considered as an established source of cells with marrow and postmobilization peripheral blood. The limited number of cells still remains a problematic element restricting their use, especially in adults who require to be grafted with a higher cell number. Improving the quality of harvested cord blood, at least in terms of volume and amount of cells, is essential to decrease the number of discarded units. In this review, we examine several variables related to parturient, pregnancy, labor, delivery, collection, the newborn, umbilical cord, and placenta. We aim to understand the biologic mechanisms that can impact cord blood quality. This knowledge will ultimately allow targeting donors, which could provide a rich graft and improve the efficiency of the collection.

Abstract
BACKGROUND The total nucleated cell dosage of umbilical cord blood (UCB) is an important factor in determining successful allogeneic hematopoietic stem cell transplantation after a minimum human leukocyte antigen donor-recipient match. The northern South American population is in need of a new-generation cord blood bank that cryopreserves only units with high total nucleated cell content, thereby increasing the likelihood of use. Colombia set up a public cord blood bank in 2014; and, as a result of its research for improving high total nucleated cell content, a new strategy for UCB collection was developed. STUDY DESIGN AND METHODS Data from 2933 collected and 759 cryopreserved cord blood units between 2014 and 2015 were analyzed. The correlation of donor and collection variables with cellularity was evaluated. Moreover, blood volume, cell content, CD34+ count, clonogenic capacity, and microbial contamination were assessed comparing the new method, which combines in utero and ex utero techniques, with the conventional strategies. RESULTS Multivariate analysis confirmed a correlation between neonatal birth weight and cell content. The new collection method increased total nucleated cell content in approximately 26% and did not alter pre-cryopreservation and post-thaw cell recovery, viability, or clonogenic ability. Furthermore, it showed a remarkably low microbial contamination rate (1.2%). CONCLUSION The strategy for UCB collection developed at the first Colombian public cord blood bank increases total nucleated cell content and does not affect unit quality. The existence of this bank is a remarkable breakthrough for Latin-American patients in need of this kind of transplantation.

Abstract
Umbilical cord blood (CB) can be used as an alternative hematopoietic stem cell source for transplantation in hematological malignancy and blood disorders. The success of transplantation is highly related to the levels of total nucleated cell and CD34+ cell counts. The evaluation of optimal conditions can decrease the rate of graft rejection due to low cell count and increases the quality of CB units (CBUs) in the blood bank and the success rate of engraftment. To this end, we review the maternal and infant parameters affecting the quality and quantity of CBUs.

Abstract
Umbilical cord blood (UCB) contains hematopoietic stem cells and multipotent
mesenchymal cells useful for treatment in malignant/nonmalignant
hematologic-immunologic diseases and regenerative medicine. Transplantation outcome
is correlated with cord blood volume (CBV), number of total nucleated cells (TNC),
CD34+ progenitor cells and colony forming units in UCB donations. Several studies
have addressed the role of maternal/neonatal factors associated with the
hematopoietic reconstruction potential of UCB, including: gestational age, maternal
parity, newborn sex and birth weight, placental weight, labor duration and mode of
delivery. Few data exist regarding as to how time influences UCB collection and
banking patterns. We retrospectively analyzed 17.936 cord blood donations collected
from 1999 to 2011 from Tuscany and Apulia Cord Blood Banks. Results from generalized
multivariable linear mixed models showed that CBV, TNC and CD34+ cell were
associated with known obstetric and neonatal parameters and showed rhythmic patterns
in different time domains and frequency ranges. The present findings confirm that
volume, total nucleated cells and stem cells of the UCB donations are hallmarked by
rhythmic patterns in different time domains and frequency ranges and suggest that
temporal rhythms in addition to known obstetric and neonatal parameters influence
CBV, TNC and CD34+ cell content in UBC units.

Abstract
OBJECTIVE To characterize the primitive stem cell content of cord blood with regard to neonatal parameters. METHODS In this cross-sectional study, CD34+ and CD90+ cells content were enumerated by flow-cytometry method. Their associations with various neonatal parameters like birth weight, gender, gestational age and mode of delivery were analyzed by univariate analysis. Multivariable linear regression model was then developed to further explain the effect of neonatal factors on these primitive cell counts. RESULTS From a total of 106 recruited subjects, gender of the neonate did not have any influence on the expression of these proteins (CD34 and CD90) of cord blood stem cells or progenitors. Multi variable linear regression analysis using CD34+ and CD90+ cell counts as dependent variables revealed that birth weight and the mode of delivery were significant predictors of these cell counts. CONCLUSIONS The present study suggests that birth weight and mode of delivery of the neonates influences cord blood stem cell yield.

Abstract
BACKGROUND One of the major limitations of umbilical cord blood (UCB) as hematopoietic stem cell source is its restricted cell number. In mothers who are candidates for stem cell donation, there are variables that affect the quantity and quality of UCB units. The aim of this study was to determine if obstetric, maternal, and fetal factors modify the number of lymphocyte subsets in UCB units. STUDY DESIGN AND METHODS This was a prospective, observational study. In UCB units, the numbers of CD34, NK, NKT, iNKT, Type 1 dendritic cells (DCs), Type 2 DCs, T γδ, T CD4+, T CD8+ lymphocytes, CD4+CD25+FoxP3+, and CD8+CD25+FoxP3+ T regulatory (Treg) cells were quantified by flow cytometry. RESULTS Fifty-four UCB units were included; the donors' mean weight was 75 kg (range, 52 to 102 kg) and they had a mean body mass index (BMI) of 30 kg/m(2) (range 22 to 40 kg/m(2) ), of which 12 (22%) had a normal BMI, 14 (26%) were overweight, and 28 (52%) were obese. The mean number of CD34+ cells was 4.45 × 10(6) (range, 0.7 × 10(6) to 20.5 × 10(6) ). The number of NKT, CD3+, CD4+, CD8+, and CD8+CD25+FoxP3+ Treg cells was significantly higher in overweight or obese mothers; CD34+ cells were decreased in the same group. The number of iNKT and CD34+ cells was decreased in newborns weighing above the average. CONCLUSIONS Maternal factors such as BMI, and fetal factors such as weight at birth, should be added to the selection criteria of UCB donors.

Abstract
BACKGROUND As processing and cryopreservation of cord blood is time consuming and costly, it is essential to select units with optimal CD34+ cells, total nucleated cell (TNC) number and colony forming units (CFUs). These are the most important factors affecting outcome of UCB transplantation and are influenced by various maternal and neonatal factors. AIM AND OBJECTIVES To determine the maternal and neonatal factors affecting TNC and CD34+ cell counts in cord blood so as to aid in proper selection of cord blood units for cryopreservation. MATERIALS AND METHODS A total of 100 UCB units were collected from normal vaginal deliveries, processed and assessed for volume, TNC, CD34+ cell count and CFU-GM. These parameters were then analyzed to find out whether they correlated with maternal and neonatal characteristics such as mother's age, parity, gestational age, baby's birth weight, and sex. RESULTS The volume of CB collected significantly correlated with the TNC, CD34+ cell, and CFU-GM yields (P < 0.02). A heavier placenta (P < 0.05), and a heavier baby (P < 0.002) were associated with a significantly greater volume of CB whereas the age, parity of mother and the sex of the baby had no significant effect. CONCLUSION The only factors found to affect the TNC and CD34+ cell counts significantly were weight of the baby and placenta and the volume of cord blood collected. Since these factors are of prognostic significance, their analysis will aid in deciding which UCB unit should be processed and cryopreserved for UCB banking and subsequent transplantation.

Abstract
BACKGROUND Umbilical cord blood (UCB) has rapidly become a clinically useful alternative stem cell source. Many variables have been used to evaluate a UCB unit and predict transplant outcomes. The objective of this study was to measure the expression of hematopoietic stem cells in UCB and its relation to certain maternal and neonatal physiologic factors to establish optimum criteria for UCB donor selection. STUDY DESIGN AND METHODS Two hundred UCB units were collected from normal uncomplicated vaginal and cesarean deliveries. Total volume was noted and immediately assessed for total nucleated cell (TNC) count and CD34+ cell concentration. Assessment of maternal and neonatal variables such as mode of delivery, placental weight, baby's birthweight, and sex was made. RESULTS The volume of the donations ranged from 42.0 to 126 mL, the TNC count ranged from 5 × 10(9) to 28.7 × 10(9) cells/L, and CD34+ cells ranged from 0.03% to 0.62%. There was a significant positive correlation between cord blood volume and cesarean section (p = 0.01) and placental weight (p = 0.02). There was a significant positive correlation with a p value of less than 0.05 between the number of CD34+ cells and UCB volume and TNC. There was no significant difference between the variables and the TNC count. CONCLUSION Our study concludes that cord units collected for banking should be obtained by selecting units of larger volumes, of higher TNCs, from female babies with heavy placenta, and from babies delivered via cesarean section.

Abstract
Hematopoietic stem and progenitor cell (HSPC) transplantations require prior harvesting of allogeneic or autologous HSPCs. HSPCs are usually present in bone marrow (BM) during the entire life, in cord blood (CB) at birth, or in peripheral blood (PB) under particular circumstances. HSPCs were first harvested in BM and later in CB and PB, as studies showed interesting features of such grafts. All harvesting methods were in use throughout the years, except BM harvesting for HSPC autologous transplantation, which was replaced by PB harvesting. BM, CB, and PB harvesting methods have been developed, and materials and devices technically improved to increase the number of HSPCs harvested. In parallel, knowing the features of the donors or patients associated with successful numbers of HSPCs allows the adaptation of appropriate harvesting methods. Moreover, it is important to ensure the safety of donors or patients while harvesting. This review describes the methods used for harvesting based on recent studies or developments around these methods, and more particularly, the means developed to increase the numbers of HSPCs harvested in each method. It also explains briefly the influence of technical improvements in HSPC harvesting on potential changes in HSPC graft composition.

Abstract
OBJECTIVES To comparatively analyze maternal and fetal factors and quality markers of blood samples in a public umbilical cord blood bank. METHOD This is a cross-sectional descriptive study that revisited 458 records of donations from September 2009 to March 2013 at the Hemocentro de Santa Catarina. The means of markers were used to define cutoff points for the quality of cord blood. RESULTS Most donations came from women with ages between 18 and 29 years (62.8%), gestational age≥40 weeks (55.2%), vaginal delivery (51.3%), primiparous (41.4%), and with male newborns (54.4%) weighing between 3000 and 3499g (41.8%). The volume of the donations ranged from 71.6 to 275.2mL, the total nucleated cell count ranged from 4.77×10(8) to 31.0×10(8) cells and CD34(+) cells ranged from 0.05 to 1.23%. There were statistically significant differences in the volume with respect to gestation age>38 weeks (p-value=0.001), cesarean section (p-value<0.001) and birth weight>3500g (p-value<0.001). The total nucleated cell count was positively affected by cesarean section (p-value=0.022) and birth weight>3500g (p-value<0.001). There was no statistically significant difference between the variables and the percentage of CD34(+) cells. CONCLUSIONS Delivery route and birth weight influence the volume of cord blood and the total nucleated cell count. Gestational age influences only the volume of cord blood.

Optimizing donor selection for public cord blood banking: influence of maternal, infant, and collection characteristics on cord blood unit quality. Transfusion 2014; 54:340-52. [PMID: 23711284 PMCID: PMC3766489 DOI: 10.1111/trf.12257] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2013] [Revised: 04/07/2013] [Accepted: 04/09/2013] [Indexed: 01/18/2023]
Abstract
BACKGROUND Banked unrelated donor umbilical cord blood (CB) has improved access to hematopoietic stem cell transplantation for patients without a suitably matched donor. In a resource-limited environment, ensuring that the public inventory is enriched with high-quality cord blood units (CBUs) addressing the needs of a diverse group of patients is a priority. Identification of donor characteristics correlating with higher CBU quality could guide operational strategies to increase the yield of banked high-quality CBUs. STUDY DESIGN AND METHODS Characteristics of 5267 CBUs donated to the Carolinas Cord Blood Bank, a public bank participating in the National Cord Blood Inventory, were retrospectively analyzed. Eligible CBUs, collected by trained personnel, were processed using standard procedures. Routine quality and potency metrics (postprocessing total nucleated cell count [post-TNCC], CD34+, colony-forming units [CFUs]) were correlated with maternal, infant, and collection characteristics. RESULTS High-quality CBUs were defined as those with higher post-TNCC (>1.25 × 10(9)) with CD34+ and CFUs in the upper quartile. Factors associated with higher CD34+ or CFU content included a shorter interval from collection to processing (<10 hr), younger gestational age (34-37 weeks; CD34+ and CFUs), Caucasian race, higher birthweight (>3500 g), and larger collection volumes (>80 mL). CONCLUSIONS We describe characteristics identifying high-quality CBUs, which can be used to inform strategies for CBU collection for public banks. Efforts should be made to prioritize collections from larger babies born before 38 weeks of gestation. CBUs should be rapidly transported to the processing laboratory. The lower quality of CBUs from non-Caucasian donors highlights the challenges of building a racially diverse public CB inventory.

Abstract
BACKGROUND The greatest limiting factor in the use of umbilical cord blood (UCB) for transplantations is the number of stem cells available in any given collected unit. This study examines maternal, neonatal, and obstetric factors that influence the suitability for banking and transplantation of UCB units collected in utero. STUDY DESIGN AND METHODS This study examined 7839 UCB units collected in utero at two hospitals from August 1, 2008, to August 31, 2011. The variables were collected from cord blood records, patient charts, delivery records, and data processed by StemCyte, Inc. (Covina, CA), our parent bank. The mean total nucleated cell (TNC) count between units selected for transplant and those banked but not selected for transplant were also compared. RESULTS Of the 11 variables evaluated, six had a significant influence on the acceptable banking TNC count of at least 90 × 10(7) . Of these, cord blood volume was the best predictor. The other variables that were predictors of the acceptable TNC count of significance were gestational age, infant race, parity, birthweight, and infant sex. The minimal bankable TNC count for banking is considerably lower than the mean TNC count of units actually selected for transplantation. CONCLUSION Maternal, neonatal, and obstetric factors can all influence the acceptability of a cord blood unit collected in utero for banking. Furthermore, units with high TNC counts are more likely to be selected for banking. Identifying these variables in potential donors can likely increase the number of adequate collections.

Abstract
BACKGROUND Umbilical cord blood (UCB) represents an alternative source of stem cells for transplantation for the treatment of hematologic malignancies and genetic disorders. There is scarce information detailing cord blood bank (CBB) collection and transplantation activities from developing countries. We documented our experience at a public university hospital in northeast Mexico. STUDY DESIGN AND METHODS We carried out a retrospective and descriptive analysis of our CBB activity during an 8-year period from May 2002 to September 2010. Collection, processing, and cryopreservation of CB were carried out following standard operating procedures. The minimum volume and total nucleated cell (TNC) content for cryopreservation were 80 mL and 8.0 × 10(8) , respectively. RESULTS A total of 1256 UCB units were collected; 428 (34%) were banked and 828 (66%) were discarded. The main reason for exclusion was biologic: low volume and/or low number of TNC accounted for 84% of the total discarded units. Cryopreserved cord blood units (CBUs) had a median volume of 113.8 mL (range, 80-213.2 mL) and 13.0 × 10(8) (range, 8 × 10(8) -36.6 × 10(8) ) TNCs. Cell viability was 99.3% (88-100%). The median CD34+ cell content was 4.0 × 10(6) (0.46 × 10(6) -19.38 × 10(6) ). Sixteen units have been released for transplantation, leading to a utilization rate of 3.7%. CONCLUSION CBB demands considerable human and financial resources; it is then essential for centers at developing countries to share their experience, results, and databases to increase the probability of finding matching units for their patients. Efforts to create and maintain CBBs allow to offer this therapeutic option at an affordable cost.

Abstract
Stem cells, both embryonic and adult, due to the potential for application in tissue regeneration have been the target of interest to the world scientific community. In fact, stem cells can be considered revolutionary in the field of medicine, especially in the treatment of a wide range of human diseases. However, caution is needed in the clinical application of such cells and this is an issue that demands more studies. This paper will discuss some controversial issues of importance for achieving cell therapy safety and success. Particularly, the following aspects of stem cell biology will be presented: methods for stem cells culture, teratogenic or tumorigenic potential, cellular dose, proliferation, senescence, karyotyping, and immunosuppressive activity.

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
The objective of the study was to evaluate the current standard practice of using volume and total nucleated cell (TNC) count for the selection of cord blood (CB) units for cryopreservation and further transplantation. Data on 794 CB units whose CD34+ cell content was determined by flow cytometry were analyzed by using a receiver operating characteristic (ROC) curve model to validate the performance of volume and TNC count for the selection of CB units with grafting purposes. The TNC count was the best parameter to identify CB units having 2 × 10(6) or more CD34+ cells, with an area under the ROC curve of 0.828 (95% confidence interval, 0.800-0.856; P < .01) and an efficiency of 75.4%. Combination of parameters (TNC/mononuclear cells [MNCs], efficiency 74.7%; TNC/volume, efficiency 68.9%; and volume/MNCs, efficiency 68.3%) did not lead to improvement in CB selection. All CB units having a TNC count of 8 × 10(8) or more had the required CD34+ cell dose for patients weighing 10 kg or less.

Abstract
Birthweight and the hematopoietic progenitor cell content in cord blood affect and reflect fetal development, and MHC has been reported to play an important role in intrauterine growth. In this study, we assessed HLA-A, -B and -DRB1 polymorphisms, birthweight and cord blood CD34(+) cell content in 1628 full-term healthy neonates to identify the HLA alleles that are associated with fetal growth in Koreans. HLA-A*31, B*47, B*51, DRB1*04 showed positive association and HLA-A*03, A*24, A*30, B*07, B*52, B*58, DRB1*03 showed negative association with birthweight and/or CD34(+) cell content; additionally, there was a greater association in homozygotes than heterozygotes revealed in the trend analysis of birthweight centile with candidate allele zygosity (A*24, P= 0.018; DRB1*04, P= 0.047). Among these alleles, HLA-A*24 and DRB1*03 showed significant negative association with birthweight and/or CD34(+) cell content after Bonferroni correction, suggesting a significant association of these alleles with fetal growth in late pregnancy (A*24, P= 0.002, P(c) = 0.026; DRB1*03, P < 0.001, P(c) < 0.001). Various populations should be analyzed to identify different or consistent factors among ethnicities. Furthermore, a larger scale study that includes pre-terms will aid in the comprehensive understanding of these associations.
