Filter by:Chronic graft-versus-host disease (cGVHD) is a clinicopathological syndrome caused by donor lymphocytes attacking the recipient's organs during the process of reestablishing donor immunity after allogeneic hematopoietic stem cell transplantation (allo-HSCT), with an incidence of about 30%-70%. The clinical manifestations of cGVHD are varied, the course of the disease is prolonged, and the quality of life of patients is affected, and the long-term survival is affected. Among them, oral cGVHD is the most common type, which mainly presents with lichen planus, oral ulcers, mucosal atrophy, erythema and pain. At present, the treatment of oral cGVHD is based on systemic treatment and local hormone-containing gargling solution and local photochemotherapy. The former is easy to be complicated by oral local fungal infection, while the latter has no such equipment in China. Therefore, it is urgent to establish a simple, effective and low-toxicity local treatment for oral cGVHD. Mesenchymal stem cells (MSCs) are one of the most widely used cell products in clinic. The combination of MSCS and hematopoietic stem cells can improve the success rate of transplantation and accelerate hematopoietic reconstruction. The applicant team previously completed a national multi-center clinical study on MSCs prevention of cGVHD, which proved that sequential infusion of MSCs can effectively reduce the incidence of cGVHD, and the mechanism is that MSCs regulate Th1: Th2 balance and promote the differentiation of T cells to Th1 direction. Our previous mechanism study provides an important theoretical basis for MSCs treatment of oral cGVHD. According to the clinical needs and the rich experience of our research group in the field of MSCs clinical research, we plan to use dressing containing MSCs for the local treatment of oral cGVHD, so as to improve the lesion degree of oral cGVHD and improve the quality of life of allo-HSCT patients, and provide clinical experience for reference for the local treatment of MSCs graft-versus-host disease.
To evaluate the efficacy and safety of Cytori Celution System in Hungarian patients with diabetic leg ulcers.
To evaluate the efficacy and safety of Cytori Celution System in Hungarian patients with chronic non-healing venous leg ulcers.
This is a clinical trial for chronic pancreatitis (CP) patients undergoing total pancreatectomy with islet autotransplantation (TP-IAT). Participants will be randomized to either bone marrow-derived mesenchymal stem cells (MSCs) or control with the standard of care. Participants will be followed for one-year post-transplant.
This study is a 24-week single-center, randomized, double-blind, placebo-controlled trial. The trial includes a 3-week early screening and lifestyle education period, 6-week treatment period, and 18-week follow-up period. Chinese type 2 diabetic subjects receiving traditional hypoglycemic treatment were randomly assigned to umbilical cord mesenchymal stem cell or placebo infusion therapy to observe the efficacy and safety of umbilical cord mesenchymal stem cell infusion therapy.
The purpose of this study is to test the safety and efficacy of Umbilical Cord-derived Mesenchymal Stromal Cells (UCMSC) for the treatment of Systemic Sclerosis (SSc).
This clinical trial assessed the safety of human umbilical cord mesenchymal stem cell therapy in 15 patients with diabetic nephropathy. Fifteen subjects received umbilical cord mesenchymal stem cell therapy 3 times. Approximately 1 × 106/kg of human umbilical cord mesenchymal stem cells were administered by peripheral intravenous infusion once a month .Endpoints:Primary endpoint: Safety and adverse events (safety and tolerability of umbilical cord mesenchymal stem cell therapy within 60 weeks).Secondary endpoint indicators:Efficacy measures: eGFR, urinary albumin-to-creatinine ratio, and percentage changes of 24-h urinary protein quantities from baseline to 60 weeks.
Kidney transplantation is a good treatment option for people with kidney disease. However, there is still much to learn about how to best care for the transplanted kidney and keep it functioning for a long time. Transplant recipients receive induction therapy and immunosuppression (anti-rejection) drugs to prevent their body from rejecting the new kidney. These drugs are used to prevent the immune system from attacking the transplanted kidney. This research study will evaluate the safety and activity of mesenchymal stromal stem cells (MSCs) infusion compared to saline-only infusion in reducing the immune suppression necessary to achieve optimal renal function in renal transplant recipients. All participants will receive routine care: basiliximab, tacrolimus, mycophenolate mofetil, and corticosteroids.
To investigate the biological characteristics of adipose tissue-derived mesenchymal stem cells(AMSCs) and its treatment effects on chronic renal failure.
The purpose of this study is to evaluate the utility of treating patients experiencing graft failure after autologous hematopoietic stem cell transplantation with ex-vivo-expanded BM-drived mesenchymal stem cells from third-party donors or mesenchymal stem cells combined with cord blood. The first objective of this study was to evaluate the effect of such treatment on graft failure, and second object was to investigate the safety of such treatment.
