Intestinal ischemia is a devastating intraabdominal emergency that often necessitates surgical intervention. Mortality rates can be high, and patients who survive often have significant long-term morbidity. The implementation of traditional medical therapies to prevent or treat intestinal ischemia have been sparse over the last decade, and therefore, the use of novel therapies are becoming more prevalent. Cellular therapy using mesenchymal stromal cells is one such treatment modality that is attracting noteworthy attention in the scientific community...

BACKGROUND AIMS: We found defocused low-energy shock wave (DLSW) could be applied in regenerative medicine by activating mesenchymal stromal cells. However, the possible signaling pathways that participated in this process remain unknown. In the present study, DLSW was applied in cultured rat adipose tissue-derived stem cells (ADSCs) to explore its effect on ADSCs and the activated signaling pathways. METHODS: After treating with DLSW, the cellular morphology and cytoskeleton of ADSCs were observed...

BACKGROUND AIMS: Human Wharton's jelly-derived mesenchymal stromal cells (hWJMSCs) are possibly the most suitable allogeneic cell source for stromal cell therapy and tissue engineering applications because of their hypo-immunogenic and non-tumorigenic properties, easy availability and minimal ethical concerns. Furthermore, hWJMSCs possess unique properties of both adult mesenchymal stromal cells and embryonic stromal cells. The human umbilical cord (UC) is approximately 50-60 cm long and the existing studies in the literature have not provided information on which segment of the UC was studied...

BACKGROUND AIMS: There is a critical unmet need to develop regenerative therapies for the demyelinating disease multiple sclerosis (MS). We previously characterized the immunoregulatory and trophic properties of neural progenitors derived from bone marrow mesenchymal stromal cells (MSC-NPs) and established that cells derived from MS and non-MS patients alike were therapeutically viable. In an experimental model of MS, intrathecal MSC-NP injection resulted in disease amelioration with decreased T-cell infiltration, and less severe lesion pathology associated with recruitment of resident progenitors to inflammatory sites...

BACKGROUND AIMS: Few studies have examined the migration pattern of natural killer (NK) cells, especially after radiation treatment for cancer. We investigated whether irradiation can modulate the expression of chemokines in cancer cells and the migration of NK cells to irradiated tumor cells. METHODS: The expression of chemokine receptors (CXCR3, CXCR4 and CXCR6) on interleukin-2 (IL-2)/IL-15-activated NK cells was assessed using flow cytometry. Related chemokine ligands (CXCL11, CXCL12 and CXCL16) in human breast cancer cell lines (MCF7, SKBR3 and MDA-MB231) irradiated at various doses were assessed using reverse transcription-polymerase chain reaction (RT-PCR), fluorescence-activated cell sorting (FACS) and enzyme-linked immunosorbent assay (ELISA)...

BACKGROUND AIMS: Aberrant production of reactive oxygen species (ROS) and its impact on the integrity of genomic DNA have been considered one of the major risk factors for the loss of dopaminergic neurons in Parkinson's disease (PD). Stem cell transplantation as a strategy to replenish new functional neurons has great potential for PD treatment. However, limited survival of stem cells post-transplantation has always been an obstacle ascribed to the existence of neurotoxic environment in PD patients...

Intraspinal stem cell (SC) transplantation represents a new therapeutic approach for amyotrophic lateral sclerosis (ALS) clinical trials. There are considerable difficulties in designing future efficacy trials, some related to the field of ALS and some that are specific to SCs or the mode of delivery. In October 2015, the most controversial points on SC transplantation were addressed during an international workshop intended to bring together international SC and ALS researchers in a public discussion on a topic for which expertise is limited...

BACKGROUND AIMS: Human parainfluenza virus-3 (HPIV) is a common cause of respiratory infection in immunocompromised patients and currently has no effective therapies. Virus-specific T-cell therapy has been successful for the treatment or prevention of viral infections in immunocompromised patients but requires determination of T-cell antigens on targeted viruses. METHODS: HPIV3-specific T cells were expanded from peripheral blood of healthy donors using a rapid generation protocol targeting four HPIV3 proteins...

Survival of ex vivo expanded hematopoietic stem cells (HSC) and progenitor cells is low with the standard cryopreservation procedure. We recently showed that the efficiency of cryopreservation of these cells may be greatly enhanced by adding a serum-free xeno-free culture medium (HP01 Macopharma), which improves the antioxidant and biochemical properties of the cryopreservation solution. Here we present the clinical-scale validation of this cryopreservation procedure. The hematopoietic cells expanded in clinical-scale cultures were cryopreserved applying the new HP01-based procedure...

Dendritic cell (DC) vaccines are an immunotherapeutic approach to cancer treatment that use the antigen-presentation machinery of DCs to activate an endogenous anti-tumor response. In this treatment strategy, DCs are cultured ex vivo, exposed to tumor antigens and administered to the patient. The ex vivo culturing provides a unique and powerful opportunity to modify and enhance the DCs. As such, a variety of genetic engineering approaches have been employed to optimize DC vaccines, including the introduction of messenger RNA and small interfering RNA, viral gene transduction, and even fusion with whole tumor cells...

The cell therapy industry has grown rapidly over the past 3 decades, and multiple clinical trials have been performed to date covering a wide range of diseases. The most frequently used cell is mesenchymal stromal cells (MSCs), which have been used largely for their anti-inflammatory actions and in situations of tissue repair and although they have demonstrated a good safety profile, their therapeutic efficacy has been limited. In addition to these characteristics MSCs are being used for their homing and engraftment properties and have been genetically modified to enable targeted delivery of a variety of therapeutic agents in both malignant and nonmalignant conditions...

The battle with human immunodeficiency virus (HIV) has been ongoing for more than 30 years, and although progress has been made, there are still significant challenges remaining. A few unique features render HIV to be one of the toughest viruses to conquer in the modern medicine era, such as the ability to target the host immune system, persist by integrating into the host genome and adapt to a hostile environment such as a single anti-HIV medication by continuously evolving. The finding of combination anti-retroviral therapy (cART) about 2 decades ago has transformed the treatment options for HIV-infected patients and significantly improved patient outcomes...

Over the last two decades, harnessing the power of the immune system has shown substantial promise. Specifically, the successes that chimeric antigen receptor (CAR) T cells achieved in the treatment of hematologic malignancies provided a concrete platform for further development in solid tumors. Considering that the latter contribute more than three quarters of cancer-related deaths in humans makes it clear that solid tumors represent the larger medical challenge, but also the larger developmental promise in the market...

The past several years have been marked by extraordinary advances in clinical applications of immunotherapy. In particular, adoptive cellular therapy utilizing chimeric antigen receptor (CAR)-modified T cells targeted to CD19 has demonstrated substantial clinical efficacy in children and adults with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) and durable clinical benefit in a smaller subset of patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or B-cell non-Hodgkin lymphoma (B-NHL)...

The capacity of natural killer (NK) cells to recognize and kill transformed cells suggests that their infusion could be used to treat cancer. It is difficult to obtain large numbers of NK cells ex vivo by exposure to cytokines alone but the addition of stimulatory cells to the cultures can induce NK cell proliferation and long-term expansion. Some of these methods have been validated for clinical-grade application and support clinical trials testing feasibility and safety of NK cell administration. Early data indicate that ex vivo expansion of NK cells from healthy donors or from patients with cancer is robust, allowing multiple infusions from a single apheresis...
