Biobanks are storage places for biospecimens that can be used for current and future scientific research. Biospecimens are exceptional sources of biological data that can be potentially translated from molecular and genetic information to clinically relevant treatment modalities. Examples of such biospecimens include, but are not limited to, blood, skin, hair, saliva, stem cells, DNA, and RNA. The volume of biospecimens worldwide continues to grow at an extraordinary rate posing a challenge for biobanks to manage this growth...

Direct reprogramming of human somatic cells toward induced pluripotent stem cells holds great promise for regenerative medicine and basic biology. We used a high-throughput siRNA screening assay in the initiation phase of reprogramming for 784 genes belonging to kinase and phosphatase families and identified 68 repressors and 22 effectors. Six new candidates belonging to the family of the G protein-coupled receptors (GPCRs) were identified suggesting an important role for this key signalling pathway during somatic cell induced reprogramming...

Multiple system atrophy is a sporadic progressive degenerative disease which is characterized by multiple central nervous systems involved. So far, there is no effective medicine to cure MSA. The main research direction of treatment includes immunization transplantation and cytotherapy. Human umbilical cord blood is the residue of blood in the placenta and umbilical cord after fetal delivery. It is the most abundant cell bank and its usage is not limited to treat hematological diseases. The researches about hUCB-MNC treatment on MSA are increasing gradually...

Recent outstanding clinical results demonstrated by engineered T cells, including chimeric antigen receptors, have already facilitated further researches that broaden their applicability. One such direction is to explore new T cell sources for allogeneic "off-the-shelf" adoptive immunotherapy. Human pluripotent stem cells may serve as an alternative cell source for this purpose due to its unique features of infinite propagation ability and pluripotency. Here, we describe the current state of engineered T cell transfer with the focus on cell manufacturing processes and the potentials and challenges of induced-pluripotent stem cell-derived T cells as a starting material to construct off-the-shelf T cell bank...

Soldiers involved in combat operations worldwide may be subjected to a wide array of tissue-specific injuries of varying degrees, thereby undergoing complicated medical treatments and prolonged rehabilitations. In many cases involving inadequate recovery, soldiers are further mentally traumatized as they can no longer serve their beloved country. In addition, many severe injuries can lead to soldiers being incapacitated for life and unable to perform even the most basic day-to-day activities. Present therapy for combat injuries is majorly aimed at alleviating pain and limiting further tissue damage from secondary infections...

Corneal limbal epithelial stem cells (LESCs) are responsible for continuously renewing the corneal epithelium, and thus maintaining corneal homeostasis and visual clarity. Human pluripotent stem cell (hPSC)-derived LESCs provide a promising cell source for corneal cell replacement therapy. Undefined, xenogeneic culture and differentiation conditions cause variation in research results and impede the clinical translation of hPSC-derived therapeutics. This protocol provides a reproducible and efficient method for hPSC-LESC differentiation under xeno- and feeder cell-free conditions...

The genetic resources of aquatic biomedical model organisms are the products of millions of years of evolution, decades of scientific development, and hundreds of millions of dollars of research funding investment. Genetic resources (e.g., specific alleles, transgenes, or combinations) of each model organism can be considered a form of scientific wealth that can be accumulated and exchanged, typically in the form of live animals or germplasm. Large-scale maintenance of live aquatic organisms that carry these genetic resources is inefficient, costly, and risky...

Mesenchymal stem cells (MSCs) as a source for regenerative medicine are now the subject of much clinical attention. There are high expectations due to their safety, low tumorigenic risk, and low ethical concerns. MSC therapy has been approved for acute graft-versus host diseases since 2015. Tooth-derived MSCs are known to have a great potential in their proliferation and differentiation capacities, even when compared with bone-marrow-derived MSCs. In particular, stem cells from human exfoliated deciduous teeth (SHEDs) are the best candidates for personal cell banking (dental pulp cell bank), because they can be obtained less invasively in the natural process of individual growth...

Cell therapy is emerging as a very promising therapeutic modality against cancer, spearheaded by the clinical success of chimeric antigen receptor (CAR) modified T cells for B cell malignancies. Currently, FDA-approved CAR-T cell products are based on engineering of autologous T cells harvested from the patient, typically using a central manufacturing facility for gene editing before the product can be delivered to the clinic and infused to the patients. For a broader implementation of advanced cell therapy and to reduce costs, it would be advantageous to use allogeneic "universal" cell therapy products that can be stored in cell banks and provided upon request, in a manner analogous to biopharmaceutical drug products...

BACKGROUND/PURPOSE: Exosomes may constitute a more practical alternative to live cells in select stem cell-based therapies. We sought to compare exosomes from two mesenchymal stem cell (MSC) sources relevant to perinatal and pediatric diseases. METHODS: Exosomes were isolated by reagent-enhanced centrifugation from cell culture media of banked human bone marrow (bm) and amniotic fluid (af) MSCs after serum starvation. Characterization was by flow exometry for tetraspanin markers CD9, CD63, and CD81, transmission electron microscopy for size and morphology, and tunable resistive pulse sensing for size distribution and concentration...

Mesenchymal stem cells (MSCs) are well known for their great potential in clinical applications. In fact, MSCs can differentiate into several cell lineages and show paracrine behavior by releasing endogenous factors that stimulate tissue repair and modulate local immune response. Each MSC type is affected by specific biobanking issues-technical issues as well as regulatory and ethical concerns-thus making it quite tricky to safely and commonly use MSC banking for swift regenerative applications. Extracellular vesicles (EVs) include a group of 150⁻1000 nm vesicles that are released by budding from the plasma membrane into biological fluids and/or in the culture medium from varied and heterogenic cell types...

Constructs of magnetic nanocomposite hydrogels microencapsulated with stem cells are of great interest as smart materials for tissue engineering and regenerative medicine. Due to the short shelf life of such biocomposites at an ambient temperature, their long-term storage and banking at cryogenic temperatures are essential for the "off-the-shelf" availability of such biocomposites for widespread clinical applications. However, high-quality cryogenic recovery of stem cell-nanocomposite hydrogel constructs has not yet been achieved due to the damage to cells and/or microstructures of hydrogel constructs caused by ice formation, particularly during warming from cryogenic temperatures...

Recipients of hematopoietic stem cell transplantation suffering from severe immunosuppression and immune dysregulation because of GVHD or other causes are at higher risk of viral infection. Often, cytomegalovirus and EB virus are reactivated from their latent state in these patients ; viral infections thus remain a primary cause of severe morbidity and mortality. Since the 1990s, virus-specific T cells have been generated by different methods using immunogenic epitope peptides or EBV-LCL from transplant donors, and studies have demonstrated the efficacy of these methods...

BACKGROUND: For over 25 years cord blood has been used as an alternative to bone marrow for therapeutic use in conditions of the blood, immune system and metabolic disorders. Parents can decide if they would like to privately store their infant's cord blood for later use if needed or to publicly donate it. Parents need to be aware of the options that exist for their infant's cord blood and have access to the relevant information to inform their choice. The aim of this paper is to identify parent's knowledge and awareness of cord blood donation, private banking options and stem cell use, and parent sources and preferred sources of this information...

The development of induced pluripotent stem cells (iPS cells) has raised the prospect of patient-specific treatments for various diseases. Theoretically, iPS cell technology avoids the limitations of human embryonic stem cells (ES cells), including poor establishment, ethical issues, and immune rejection of allogeneic transplantation. However, the immunogenicity of iPS cells has attracted the attention of researchers, and it remains unclear whether iPS cells and their derivatives will be recognized as a patient's own cells...

The probability of a Black African finding a matched unrelated donor for a hematopoietic stem cell transplant is minimal due to the high degree of genetic diversity amongst individuals of African origin. This problem could be resolved in part by the establishment of a public cord blood (CB) stem cell bank. The high prevalence of human immunodeficiency virus (HIV) amongst women attending antenatal clinics in sub-Saharan Africa together with the risk of mother-to-child transmission increases the risk of transplant transmissible infection...
