Stem Cells Reported to Improve Vision

Two patients receiving embryonic stem cells for their blinding retinal diseases reported improvement in their vision. The results were released just last week online in the medical journal Lancet. Each patient received retinal epithelial pigment cells (aka RPE cells) grown from human embryonic stem cells. RPE cells are the faulty cells in macular diseases such as ARMD … [Read more...]

Stem Cells for Stargardt’s Macular Dystrophy and Macular Degeneration

RPE Transplantation for Stargardts Disease

  Advanced Cell Technology recently announced the beginning of their landmark trial where stem cells are transplanted into patients with Stargardt's Macular Dystrophy (aka Stargardt's Disease) and dry macular degeneration. Clinical Trials for Stargardt's Begin The company announced that their phase I/II clinical trials started in mid-July with one patient each of … [Read more...]

Part 2: Transplanting Stem Cells to Treat Macular Degeneration

In the last post, we identified the Retinal Pigment Epithelium as the layer in the retina that becomes diseased in macular degeneration.  The cells, once damaged, do not have the ability to divide, regenerate or regrow.  Thus, permanent damage (i.e. loss of vision) ensues. By The Way. There are two basic types of stem cells;  embryonic stem cells and adult (or somatic) … [Read more...]

Part 1: Introduction to Stem Cells and Retinal Disease

This is the first of a small series regarding stem cells and their potential benefits to retinal diseases; principally macular degeneration and retinitis pigmentosa. As diabetic retinopathy is primarily a disease of blood vessels, i.e.poor blood flow, loss of blood flow, leaking vessels, etc., macular degeneration is actually a disease of one of the layers of the … [Read more...]
