The purpose of this study is to evaluate the short-term safety of a single intravitreal injection of autologous bone marrow stem cells in patients with retinitis pigmentosa.
A prospective phase I, nonrandomized open-label study of retinitis pigmentosa patients with best-corrected ETDRS visual acuity (BCVA) worse than 20/200. Standardized ophthalmic evaluation will be perform at baseline and at weeks 1, 4,12 and 24 (±1) following intravitreal injection of 10 x 106 bone marrow stem cells/ 0,1ml . Three measures will be used to evaluate the short-term safety of intravitreal of ABMDSC: 1) severe visual loss, defined as a drop in 15 letters on ETDRS visual acuity scale; 2) decrease in ERG response; 3) decrease in 5 square degrees on visual field; secondary safety outcomes : 1) increase in intra-ocular inflammation defined herein as anterior chamber cells and flare higher than 3+ for more than 1 month after injection according to a classification described elsewhere ; 2) decrease in CMT more than 50um; 3)genesis of abnormal tissues (teratomas) or tumors; 4) qualitative changes in retinal or choroidal perfusion, like macular nonperfusion. Secondary outcome measures will be used to evaluate the short-term efficiency of intravitreal of ABMDSC: 1) improvement in ERG response; 2) increase in visual field: 3) increase in CSMT > 50um and not related to macular edema; 4) increase > 5 letters on BCVA

The goal of this study is to determine the safety of giving a patient's own bone marrow-derived stem cells delivered with a catheter (tube) into the coronary arteries (blood vessels of the...
This study is conducted to assess whether implanting autologous, culture-expanded, mesenchymal stem cells obtained from the bone marrow of patients with early osteoarthritis, cartilage de...
Currently, There is no treatment for Premature ovarian insufficiency (POI). Very small embryonic-like stem cells (VSELs) are found in the ovary. VSELs are able to regenerate the affected o...
The secretome produced by cells within the bone marrow is significant to homeostasis. The bone marrow, a well-studied organ, has multiple niches with distinct roles for supporting stem cell functions....

Mesenchymal stem cells (MSCs) are pluripotent stem cells with the ability to differentiate into a variety of other connective tissue cells, such as chondral, bony, muscular, and tendon tissue. Bone ma...
Safety and Potential Therapeutic Effect of Two Intracavernous Autologous Bone Marrow Derived Mesenchymal Stem Cells injections in Diabetic Patients with Erectile Dysfunction: An Open Label Phase I Clinical Trial.
This open label, phase I clinical trial (NCT02945462) using 2 consecutive intracavernous autologous bone marrow-derived mesenchymal stem cells (BM-MSCs) for the first time in the treatment of diabetic...
The treatment options for diabetic retinopathy (DR) are limited. Mesenchymal stem cells (MSCs) are a promising treatment option for diabetes and its complications. In this pilot clinical trial, we eva...
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
A cell-separation technique where magnetizable microspheres or beads are first coated with monoclonal antibody, allowed to search and bind to target cells, and are then selectively removed when passed through a magnetic field. Among other applications, the technique is commonly used to remove tumor cells from the marrow (BONE MARROW PURGING) of patients who are to undergo autologous bone marrow transplantation.
Bone-marrow-derived, non-hematopoietic cells that support HEMATOPOETIC STEM CELLS. They have also been isolated from other organs and tissues such as UMBILICAL CORD BLOOD, umbilical vein subendothelium, and WHARTON JELLY. These cells are considered to be a source of multipotent stem cells because they include subpopulations of mesenchymal stem cells.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
