Cell Therapy: Replacement

Cell therapy: replacement.

Not long ago, the ability of the brain to restore function through regeneration of neural elements was thought to be nonexistent. It is now known that not only does some regenerative capacity exist, but implanted cells can integrate into the host brain, survive, and reverse neurological deficits. Neural stem cells, fetal transplants, immortalized cell lines, and bone marrow stromal cells show p...

Metastasis inhibition by BRMS1 and miR-31 replacement therapy in claudin-low cell lines

Objective(s): The growing trend of research demonstrates that dynamic expression of two metastasis repressor classes (metastasis suppressor genes and anti-metastatic miRNA) has a close relationship with tumor invasion and metastasis. Using different strategies, it was revealed that cellular levels of miR-31 and Breast cancer Metastasis Suppressor1 (BRMS1) protein, whic...

Cell Replacement and Regeneration Therapy for Diabetes

Reduction of beta cell function and a beta cell mass is observed in both type 1 and type 2 diabetes. Therefore, restoration of this deficiency might be a therapeutic option for treatment of diabetes. Islet transplantation has benefits, such as reduced incidence of hypoglycemia and achievement of insulin independence. However, the major drawback is an insufficient supply of islet donors. Transpl...

Hematopoietic stem cell gene replacement therapy.

Human gene therapy trials have begun, and by early reports are a success [1]. The initial clinical trial which demonstrated the safety of infusing genetically marked lymphocytes into humans was reported in 1990 [2]. This paved the way for researchers at the National Institutes of Health (NIH) :o begin the first therapeutic trials of treating adenosine deaminase deficient patients with genetical...
