The establishment of a biobank for stem cells, specifically umbilical cord (UC)-derived mesenchymal stromal cells (UCMSCs), is crucial for advancing medical research and regenerative therapies. A biobank provides a centralized and standardized repository of high-quality biological materials, which is essential for researchers and clinicians to explore disease mechanisms, test therapeutic approaches, and develop precision treatments. This study applied microbial testing protocols at Vinmec Hospital, including aerobic and anaerobic culture systems (BacT/ALERT® FA Plus and FN Plus), followed by bacterial identification with the VITEK® 2 Compact system, to ensure contamination-free UCMSC samples suitable for banking. A total of 1,336 UC samples were monitored at three check-points (CPs), including CP1 (UC transfer solution during collection), CP2 (cell washing buffer during isolation), and CP3 (cell culture media at P0 and P1 during expansion). Results showed that 29 cases (2.17 %) were contaminated at CP1, and only four cases (0.299 %) at CP2 showed contamination, which were identified as Candida albicans, Staphylococcus epidermidis, Escherichia coli, and Listeria monocytogenes, and were discarded. No contamination occurred at CP3, ensuring effective control during expansion. These results suggest that contamination primarily occurred during the UC collection and processing stages, while the culture and expansion procedures were not a significant source of microbial risk. Additionally, the careful implementation of these methodologies demonstrates the feasibility of generating a reliable UCMSC biobank, a cornerstone resource for personalized therapies, disease modeling, and drug discovery.</p>","PeriodicalId":9723,"journal":{"name":"Cell and Tissue Banking","volume":"27 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13102930/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147763502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were recruited using a non-probability convenience sampling method. Data were collected via an online questionnaire that assessed socio-demographic characteristics and knowledge and attitudes towards umbilical cord blood donation and banking. Awareness levels were categorized as \"no knowledge\", \"limited knowledge\", and \"sufficient knowledge\", and dichotomized as \"insufficient\" versus \"partial/sufficient\" for regression analysis. Descriptive statistics and the Chi-square test were used to analyze the data. In addition to descriptive statistics, binary logistic regression analysis was performed to identify independent factors associated with awareness of umbilical cord blood donation and banking. Statistical significance was set at p < 0.05. The average age of the pregnant women was 30.38 ± 4.48. Only 3.9% had sufficient knowledge about UCB donation and banking, while the majority (96.1%) had never received any information about UCB donation, and none had ever donated before. The main reason for not donating was a lack of information (89.7%). The income and education level of the pregnant women were significantly associated with their knowledge and attitudes towards UCB donation and banking (p < 0.05). A family history of disease positively influenced knowledge and attitudes (p < 0.05), whereas religious beliefs negatively influenced donation intentions. Again, most pregnant women (79.9%) stated that they wanted to receive education about UCB donation and banking. Binary logistic regression analysis identified education level as the strongest independent predictor of awareness. In light of these findings, education on UCB donation and banking should be included in prenatal care processes.

Furthermore, the protein levels of neuronal markers gamma-enolase (NSE), MAP-2, and β-tubulin III were assessed by immunocytochemistry (ICC) on days 7 and 14.

We applied a sol-gel method to fabricate the bioglass nanofibers and incorporated them into 3-D hydrogel (1%, 5%, and 10% wt.%). The fabricated scaffolds were characterized to determine their morphology, surface functional groups, porosity, swelling capacity, biodegradation profile, cytocompatibility, and hemocompatibility. Finally, the scaffolds were implanted in critical-size bone-defect models in the rabbit calvaria. The results showed that the calcination of precursor nanofibers to fabricate bioglass nanofibers reduced the nanofibers' diameter from around 981 nm to around 566 nm. Hydrogels containing 0%, 1%, and 5% BGNFs demonstrated no cytotoxicity, with viability percentages of 113%, 105.7%, and 112%, respectively. The 10% BGNF formulation exhibited a minor decrease in vitality (84.3%). Notably, the scaffolds promoted osteogenesis to a high degree, as evidenced by a concentration-dependent increase in mineral deposition under Alizarin Red staining. The animal studies showed that scaffold implantation supported new bone formation, as evidenced by histological analysis and micro-CT imaging. A denser, more interconnected bony network with superior mineralization (BMD) was the result of a remarkable rise in bone volume (BV/TV), trabecular thickness (Tb.Th), and trabecular number (Tb.N), as well as a decrease in trabecular separation (Tb.Sp).

Despite the clinical promise of adipose-derived mesenchymal stem cells (ADMSCs) for cartilage regeneration, whether distinct in vivo cartilage microenvironments can instruct ADMSC differentiation toward corresponding subtypes remains poorly defined. Green fluorescent protein-labeled human ADMSCs were encapsulated in a fibrin hydrogel and implanted into three representative cartilage sites-auricular (elastic), articular (hyaline), and meniscal (fibrocartilage)-in an immunodeficient rat model. Regenerated tissues were harvested at 4 weeks for histology (H&E), immunofluorescence analysis of hyaline (COL II, aggrecan), fibrocartilage (COL I, tenomodulin), and elastic (fibrillin-1, elastin) markers, and RT-PCR quantification of lineage-associated gene expression. ADMSCs survived and engrafted within all three microenvironments. Articular cartilage implants exhibited strong hyaline-like differentiation, characterized by intense COL II and aggrecan expression and upregulation of SOX9, COL2A1, and ACAN. Meniscal implants instead displayed a fibrocartilage-like profile with robust COL I and tenomodulin expression and elevated COL1A1, TNMD, and SCX transcripts. In contrast, auricular cartilage implants showed negligible expression of hyaline, fibrocartilage, or elastic markers, accompanied by global downregulation of chondrogenic and elastogenic genes. These results demonstrate that local cartilage niches exert distinct instructive effects on ADMSC fate: articular and meniscal environments effectively guide hyaline- and fibrocartilage-like differentiation, whereas the auricular niche under the tested conditions fails to support elastic or hyaline lineage commitment. Our findings highlight the decisive role of the tissue microenvironment in modulating ADMSC differentiation and underscore the need for bioengineered, niche-mimetic scaffolds to achieve subtype-specific cartilage regeneration-particularly for complex elastic tissues such as the auricle.</p>","PeriodicalId":9723,"journal":{"name":"Cell and Tissue Banking","volume":"27 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147455810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Willingness to donate and receive bone allografts in the surveyed sub-Saharan Africa settings was relatively high although marked heterogeneity existed between countries.
