Study of Umbilical Cord Mesenchymal Stem Cell-Derived Exosomes in Vitiligo

This study evaluates whether exosomes derived from human umbilical cord mesenchymal stem cells (hUMSCs-Exo) are safe and effective for treating vitiligo in adults. Vitiligo is a skin condition that causes white patches due to loss of pigment-producing cells. Current treatments have limitations, especially for patients with active disease who require oral steroids with significant side effects. This study is a single-center, randomized, controlled trial enrolling 96 adults aged 18 to 65 years with non-segmental vitiligo. Participants are divided into two groups based on disease activity: progressive vitiligo (new patches appearing or existing patches expanding in the past 3 months) and stable vitiligo (no changes in the past year). For progressive vitiligo, participants are randomly assigned to either: Experimental group: hUMSCs-Exo given by intravenous infusion every 2 weeks for 5 sessions, plus tacrolimus ointment and narrowband UVB light therapy, or Control group: oral prednisone (a standard steroid treatment) plus tacrolimus ointment and narrowband UVB light therapy For stable vitiligo, participants are randomly assigned to either: Experimental group: hUMSCs-Exo given by local injection into the white patches every 2 weeks for 5 sessions, plus tacrolimus ointment and narrowband UVB light therapy, or Control group: tacrolimus ointment plus narrowband UVB light therapy alone The treatment period lasts 12 weeks, with follow-up visits continuing to 24 weeks. The main outcome measures include improvement in skin repigmentation measured by the Vitiligo Area Scoring Index (VASI), changes in quality of life, and safety monitoring throughout the study. This study aims to establish a standardized approach for using hUMSCs-Exo in vitiligo treatment and to explore how exosomes may work by reducing oxidative stress and regulating immune responses.

Autologous Mesenchymal Stromal Cells and Islet Co-transplantation in TP-IAT

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.

Treatment With Human Umbilical Cord-derived Mesenchymal Stromal Cells in Systemic Sclerosis

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).

Mesenchymal Stromal Cells in Living Donor Kidney Transplantation

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.
