UC-MSC Cell Therapy Study for Systemic Lupus Erythematosus (SLE) Patients

The goal of this clinical trial is to evaluate the safety and effectiveness of UC-MSCs in adults with systemic lupus erythematosus (SLE). The main questions this study aims to answer are: 1. Can UC-MSCs improve kidney function and reduce SLE disease activity? 2. Are UC-MSCs safe and well-tolerated in this patient population? Participants in this study will: * Receive UC-MSCs in a single dose in addition to standard of care treatment. * Provide blood and urine samples for laboratory assessments, including biomarkers and immune profiling (e.g., cytokines, complement proteins, and autoantibodies). * Attend regular clinic visits for physical exams, disease activity scoring, and imaging tests to monitor kidney health. * Complete assessments for safety, such as monitoring for adverse events and changes in laboratory values. This study aims to provide new insights into treatment options for SLE and lupus nephritis, addressing an unmet medical need in this population.
