Progressive and inexorable β-cell dysfunction is the hallmark of type 2 diabetes mellitus (T2DM) and β-cell regeneration using stem cell may prove to be an effective modality. A total of 10 patients (8 men) with T2DM for >5 years, failure of triple oral antidiabetic drugs, currently on insulin (≥0.7 U/kg/day) at least for 1 year,
Angiogenic cell by intramuscular injection of autologous bone marrow mononuclear cells was first attempted in patients with peripheral artery disease (PAD) with critical limb ischemia, and the feasibility was shown by a randomized controlled Therapeutic Angiogenesis by Cell Transplantation (TACT) study.
Methods and Results
The present study was designed to assess the 3-year safety and clinical outcomes of this angiogenic cell by investigating the mortality and leg amputation-free interval as primary end points.
Preclinical studies have established that implantation of bone marrow-mononuclear cells, including endothelial progenitor cells, into ischaemic limbs increases collateral vessel formation. We investigated efficacy and safety of autologous implantation of bone marrow-mononuclear cells in patients with ischaemic limbs because of peripheral arterial disease.
We first did a pilot study, in which 25 patients (group A) with unilateral ischaemia of the leg were injected with bone marrow-mononuclear cells into the gastrocnemius of the ischaemic limb and with saline into the less ischaemic limb.
Stem cell therapies are being explored extensively as resultss for degenerative eye disease, either for replacing lost neurons, restoring neural circuits or, based on more recent evidence, as paracrine-mediated therapies in which stem cell-derived trophic factors protect compromised endogenous retinal neurons from death and induce the growth of new connections. Retinal progenitor phenotypes induced from embryonic stem cells/induced pluripotent stem cells (ESCs/iPSCs) and endogenous retinal stem cells may replace lost photoreceptors and retinal pigment epithelial (RPE) cells and restore vision in the diseased eye,
Bone-marrow derived mesenchymal stromal cells (MSCs) have potent immunomodulatory and tissue reparative properties, which may be beneficial in the results of inflammatory diseases such as COPD. This study examined the mechanisms by which human MSCs protect against elastase induced emphysema. Using a novel human relevant pre-clinical model of emphysema the efficacy of human MSC and optimal cell dose were investigated.
In the last two decades, mesenchymal stem cells (MSCs) have been pre-clinically utilized in the results of a variety of kinds of diseases including chronic obstructive pulmonary disease (COPD). The aim of the current study was to systematically review and conduct a meta-analysis on the published pre-clinical studies of MSC administration in the results of COPD in animal models.
The potential role of mesenchymal stem cells (MSCs) in the management of Type 2 diabetes mellitus (T2DM) has been shown with varying degrees of success in animal models and in clinical trials. Evidence shows that it affects insulin resistance and secretory dysfunction of B-cells. It has also shown potential effects on immune system dysregulation and inflammatory mediators,
