BACKGROUND: Determining the distributive fate and retention of a cell therapy product after administration is an essential part of characterizing it's biosafety profile. Therefore, regulatory guidelines stipulate that biodistribution assays are a requirement prior to advancing a cell therapy to the clinic. Here the development of a highly sensitive quantitative polymerase chain reaction (qPCR)-based method of tracking the biodistribution and retention of human mesenchymal stromal cells (hMSCs) in mice, rats or rabbits is described...

Umang G Thakkar, Aruna V Vanikar, Hargovind L Trivedi
The kidney has been considered a highly terminally differentiated organ with low proliferative potential and thus unlikely to undergo regeneration. Glomerular disease progresses to end-stage renal disease (ESRD), which requires dialysis or renal transplantation for better quality of life for patients with ESRD. Because of the shortage of implantable kidneys and complications such as immune rejection, septicemia and toxicity of immunosuppression, kidney transplantation remains a challenge. Therapeutic options available for glomerular disease include symptomatic treatment and strategies to delay progression...

BACKGROUND AIMS: Chronic wounds are a common complication of diabetes. Fibroblast-myofibroblast differentiation is important for wound repair, which is commonly impaired in non-healing wounds, and the underlying mechanisms need to be further elucidated. METHODS: We used high glucose (HG) to simulated the diabetes microenvironment and explored its effects on the biological features of fibroblasts in vitro. RESULTS: The results showed that prolonged HG induced senescence in fibroblasts through activation of p21 and p16 in a reactive oxygen species (ROS)-dependent manner, further delayed the viability and migration in fibroblasts and also depressed fibroblast differentiation through the TGF-β/Smad signaling pathway...

BACKGROUND AIMS: The effect of cryopreservation on mesenchymal stromal cell (MSC) therapeutic properties has become highly controversial. However, data thus far have indiscriminately involved the assessment of different types of MSCs with distinct production processes. This study assumed that MSC-based products are affected differently depending on the tissue source and manufacturing process and analyzed the effect of cryopreservation on a specific population of umbilical cord tissue-derived MSCs (UC-MSCs), UCX(®)...

BACKGROUND: Adipose-derived mesenchymalstromal cells (ASC) are currently tested in regenerative medicine to promote tissue reconstruction after injury. Regardingautologous purpose, the possible loss of therapeutic function and cell properties during aging have been questioned in adults. To date no reliable information is available concerning ASC from pediatric patients and a better knowledge is required for clinical applications. METHODS: Subcutaneous adipose tissue was collected from 27 donors (0-1 years old) and 50 donors (1-12 years old) and compared with adult ASC for in vitro characteristics...

BACKGROUND AIMS: Umbilical cord blood (CB) is being used as a source of hematopoietic stem cells (HSCs) and immune cells to treat many disorders. Because these cells are present in low numbers in CB, investigators have developed strategies to expand HSCs and other immune cells such as natural killer (NK) cells. The initial step in this process is to enrich mononuclear cells (MNCs) while depleting unwanted cells. The manual method of MNC enrichment is routinely used by many centers; however, it is an open system, time-consuming and operator dependent...

Large numbers of human mesenchymal stromal cells (MSCs) used for a variety of applications in tissue engineering and cell therapy can be generated by scalable expansion in a bioreactor using microcarriers (MCs) systems. However, the enzymatic digestion process needed to detach cells from the growth surface can affect cell viability and potentially the potency and differentiation efficiency. Thus, the main aim of our study was to develop biocompatible and biodegradable MCs that can support high MSC yields while maintaining their differentiation capability and potency...

BACKGROUND AIMS: The microenvironment of the chronically injured spinal cord does not allow for axonal regeneration due to glial scarring. To ameliorate this, several therapeutic strategies have been used. We investigated whether combined transplantation of chondroitinase ABC (chABC) and mesenchymal stromal cells (MSCs) genetically modified to secrete brain-derived neurotrophic factor (BDNF) with intravenous (IV) administration of MSCs can promote recovery of hindlimb function after chronic spinal cord injury (SCI)...

BACKGROUND AIMS: Primary hematopoietic stem and progenitor cells (HSPCs) are key components of cell-based therapies for blood disorders and are thus the authentic substrate for related research. We propose that ubiquitous small-volume diagnostic samples represent a readily available and as yet untapped resource of primary patient-derived cells for cell- and gene-therapy studies. METHODS: In the present study we compare isolation and storage methods for HSPCs from normal and thalassemic small-volume blood samples, considering genotype, density-gradient versus lysis-based cell isolation and cryostorage media with different serum contents...

The cell therapy industry is a fast-growing industry targeted toward a myriad of clinical indications. As the cell therapy industry matures and clinical trials hit their pivotal Phase 3 studies, there will be a significant need for scale-up, process validation, and critical raw material quality assurance. Part of the well discussed challenges of upscaling manufacturing processes there is a less discussed issue relating to the availability of raw materials in the needed quality and quantities. The FDA recently noted that over 80% of the 66 investigational new drug (IND) applications for mesenchymal stem cell (MSC) products analyzed described the use of FBS during manufacturing...

BACKGROUND AIMS: Synovial mesenchymal stem cells (MSCs) are an attractive cell source for cartilage regeneration because of their high proliferative ability and chondrogenic potential. We have performed clinical trials using synovial MSCs to regenerate articular cartilage. To achieve good clinical outcomes for cell transplantation therapy, it is important to control both quantity (cell number) and quality (pluripotency or chondrogenic potential) of the cells for transplantation. Interleukin (IL)-1β is a pro-inflammatory cytokine with significant pro-proliferative potential for mesenchymal cells...

BACKGROUND: Mesenchymal stromal cells (MSCs) are multipotent cells characterized by broad immunomodulatory properties exploited for the treatment of inflammatory disorders. However, the efficacy of MSC-based therapy is highly variable and tightly linked to MSC culture conditions and treatment schedule. Thus, the identification of novel key molecules regulating MSC immunomodulatory activities in vivo might constitute a crucial step toward the optimization of currently available clinical protocols...

BACKGROUND AIMS: Despite widespread use of umbilical cord blood (UCB) transplantation and distinct practice preferences displayed by individual UCB banks and transplant centers, little information exists on how processing variations affect patient outcomes. METHODS: We reviewed 133 adult double UCB transplants performed at a single center: 98 after reduced-intensity and 35 after myeloablative conditioning. Processing associated with contributing UCB banks and units was surveyed to identify differences in practice...

BACKGROUND AIMS: Despite ethnic diversity and ready availability of cryopreserved, human leukocyte antigen-typed cord blood (CB), delayed engraftment remains a significant hurdle to successful CB transplantation. Suboptimal homing of CB hematopoietic stem and progenitor cells (HSPCs) to the hematopoietic microenvironment (HM) is thought to be responsible and due to low levels of HSPC fucosylation. Fucosylation (decoration with sialyl-Lewis(X)) may improve HSPC homing to HM by increasing the strength of HSPC/E-selectin interactions, where E-selectin is constitutively expressed by HM microvasculature...
