Cell therapy products are frequently developed and produced without incorporating cost considerations into process development, contributing to prohibitively costly products. Herein we contextualize individual process development decisions within a broad framework for cost-efficient therapeutic manufacturing. This roadmap guides the analysis of cost of goods (COG) arising from tissue procurement, material acquisition, facility operation, production, and storage. We present the specific COG considerations related to each of these elements as identified through a 2013 International Society for Cellular Therapy COG survey, highlighting the differences between autologous and allogeneic products...

Hematopoietic stem cell transplantation (HSCT) represents the only crative treatment option for many hematological conditions but results in a profound T-cell deficiency in the post-HSCT period. Infections account for a significant proportion of non-relapse morbidity and mortality, and infections with multiple organisms either simultaneously or at different times after transplant are common. Adoptive cellular therapy (ACT) with prophylactic or therapeutic infusion of donor derived or third-party, pathogen-specific T-cells represents a novel methodology to rapidly reconstitute T-cell mediated immunity in this context...

REVIEW
Sarah I Davies, Pawel Muranski
Rapid restoration of virus-specific T immunity via adoptive transfer of ex vivo generated T cells has been proven as a powerful therapy for patients with advanced cancers and refractory viral infections such as cytomegalovirus (CMV) and Epstein-Barr virus (EBV). BK virus (BKV), John Cunningham virus (JCV), and Merkel cell carcinoma virus (MCV) are the members of the rapidly growing human polyomavirus (hPyV) family that commonly infects most healthy humans. These viruses have a clearly established potential for causing severe end-organ damage or malignant transformation, especially in individuals with weakened immunity who are unable to mount or regain endogenous T-cell responses as a result of underlying leukemia or iatrogenic immunosuppression in autoimmunity, bone marrow and solid organ transplant settings...

BACKGROUND AIMS: Cell transplants offer a new opportunity to deliver therapies with novel and complex mechanisms of action. Understanding the pharmacology of cell transplants is important to deliver this new therapy effectively. Currently, however, there are limited techniques to easily track cells after intravenous administration due to the dispersion of the graft throughout the entire body. METHODS: We herein developed an engineered cell system that secretes a luciferase enzyme to sensitively detect cell transplants independent of their locale by a simple blood test...

BACKGROUND AIMS: Growing evidence supports the therapeutic potential of bone marrow (BM)-derived stem/progenitor cells for end-stage liver disease (ESLD). We recently demonstrated that CD133(+) stem/progenitor cell (SPC) reinfusion in patients with ESLD is feasible and safe and improve, albeit transiently, liver function. However, the mechanism(s) through which BM-derived SPCs may improve liver function are not fully elucidated. METHODS: Here, we characterized the circulating SPCs compartment of patients with ESLD undergoing CD133(+) cell therapy...

BACKGROUND AIMS: Regenerative medicine employs human mesenchymal stromal cells (MSCs) for their multi-lineage plasticity and their pro-regenerative cytokine secretome. Adipose-derived mesenchymal stromal cells (ASCs) are concentrated in fat tissue, and the ease of harvest via liposuction makes them a particularly interesting cell source. However, there are various liposuction methods, and few have been assessed regarding their impact on ASC functionality. Here we study the impact of the two most popular ultrasound-assisted liposuction (UAL) devices currently in clinical use, VASER (Solta Medical) and Lysonix 3000 (Mentor) on ASCs...

BACKGROUND: Clinical trials using ex vivo expansion of autologous mesenchymal stromal cells (MSCs) are in progress for several neurological diseases including multiple sclerosis (MS). Given that environment alters MSC function, we examined whether in vitro expansion, increasing donor age and progressive MS affect the neuroprotective properties of the MSC secretome. METHODS: Comparative analyses of neuronal survival in the presence of MSC-conditioned medium (MSCcm) isolated from control subjects (C-MSCcm) and those with MS (MS-MSCcm) were performed following (1) trophic factor withdrawal and (2) nitric oxide-induced neurotoxicity...

REVIEW
Juan Gea-Banacloche
Granulocyte transfusions (GTXs) have been used to treat and prevent infections in neutropenic patients for more than 40 years, despite persistent controversy regarding their efficacy. This narrative review attempts to complement recent systematic reviews by the Cochrane Collaboration and provide both historical context and critical assessment of the most significant clinical studies published over the years. The data suggest that properly collected and promptly infused granulocytes are active against infections, both bacterial and fungal...

BACKGROUND AIMS: We have confirmed that aortic aneurysm (AA) can be regressed by the administration of bone marrow-derived mesenchymal stem cells (BM-MSCs). We investigated the kinetics of signaling pathways in AA following treatment with BM-MSCs. METHODS: Angiotensin II-infused apolipoprotein E-deficient mice were treated by intravenous injection of 1 × 10(6) BM-MSCs in 0.2 mL saline (BM-MSCs group, n = 5) or 0.2 mL saline (saline group, n = 5)...

Diabetic neuropathy (DN) is among the most debilitating complications of diabetes. Here, we investigated the effects of human dental pulp stem cell (DPSC) transplantation in Streptozotocin (STZ)-induced neuropathic rats. Six weeks after STZ injection, DPSCs were transplanted through two routes, intravenous (IV) or intramuscular (IM), in single or two repeat doses. Two weeks after transplantation, a significant improvement in hyperalgesia, grip-strength, motor coordination and nerve conduction velocity was observed in comparison with controls...

BACKGROUND AIMS: Activated NK cells (aNK) generated by expansion of a human interleukin-2-dependent NK cell line (NK-92) were shown to mediate strong anti-leukemia activity. This phase 1 study evaluated feasibility, safety, and activity of aNK cells adoptively transferred to patients with refractory/relapsed acute myeloid leukemia (AML). In addition, effects of these aNK cells on the patient's immune system were evaluated. METHODS: Two cell-dose levels (1 × 10(9) cells/m(2) and 3 × 10(9) cells/m(2)) were used...

Although therapy for chronic hepatitis C virus infection has delivered remarkable cure rates, curative therapies for hepatitis B virus (HBV) may only be available in the distant future. The possibility to eliminate or at least stably maintain low levels of HBV replication under the control of a functional anti-host response has stimulated the development of specific immunotherapies for HBV infection. We reviewed the development of T-cell therapy for HBV, highlighting its potential antiviral efficiency but also its potential toxicities in different groups of chronic HBV patients...

Adult multipotent mesenchymal stromal cells (MSCs) are considered one of the key players in physiological remodeling and tissue reparation. Elucidation of MSC functions is one of the most intriguing issues in modern cell physiology. In the present review, the interaction of MSCs and immune cells is discussed in terms of reciprocal effects, which modifies the properties of "partner" cells with special focus on the contribution of direct cell-to-cell contacts, soluble mediators and local microenvironmental factors, the most important of which is oxygen tension...

BACKGROUND: A cochlear implant (CI) is an electronic prosthesis that can partially restore speech perception capabilities. Optimum information transfer from the cochlea to the central auditory system requires a proper functioning auditory nerve (AN) that is electrically stimulated by the device. In deafness, the lack of neurotrophic support, normally provided by the sensory cells of the inner ear, however, leads to gradual degeneration of auditory neurons with undesirable consequences for CI performance...

BACKGROUND AIMS: Urothelial bladder cancer (UBC) is the second most common cancer of the genitourinary tract and for advanced forms of the disease it has a high mortality rate. There are no approved new molecularly targeted agents or chemotherapeutics for advanced UBC beyond cisplatin-based chemotherapy except the recently approved anti-programmed death ligand 1 (anti-PD-1/PD-L1) antibody. With complex genetic and epigenetic alterations in tumors, despite several druggable targets identified, to cure UBC is still a challenging unmet medical need...

Treatments based on stem cells have long been heralded for their potential to drive the future of regenerative medicine and have inspired increasing medical and business interest. The stem cell therapy market has been expanding since 2012, but earnings and profitability still lag the broader health care sector (compounded annual growth rate in annual financing of 31.5% versus 13.4%, respectively). On the basis of historical financial data, approximately $23 billion has been invested in stem cell companies since 1994, with more than 80% of this raised from 2011 through 2016...
