Stem Cell Therapy News
Since 1995, University of California, Irvine stem cell researcher Magdalene J. Seiler, PhD has pursued promising research into the development and usage of retinal sheet transplantation. The treatment is based on transplanting sheets of stem cell-derived retina, called retina organoids to the back of the eye with hopes of re-establishing the neural circuity within the eye. Recently, Seiler has received a $4.8 million grant from the California Institute of Regenerative Medicine (CIRM) to continue to develop a stem cell-based therapy for retinal diseases such as retinitis pigmentosa.
A group of research physicians have discovered that using stem cells from a person’s own bone marrow has reported success in improving vision for patients with Retinitis Pigmentosa. The bone marrow stem cells come from the same person; therefore, there can be no rejection. Of the 33 eyes studied, 45.5% of individual eyes improved and 45.5% remained stable over the follow-up period when they typically have been worsening. Vision improvement is 98.4% likely to be a consequence of this treatment.
A retinal implant allowed a 69 year old woman with macular degeneration to see more than double the usual number of letters on the vision chart. Luxturna, the gene therapy was approved by the FDA in 2017, corrects a mutation found in Leber congential amaurosis (LCA).
This story is designed to help you find an answer to the question: will a stem cell therapy work for me? To get an answer, Dr. Mary Sunderland of the Foundation Fighting Blindness Canada, suggests that you pay attention to three key points when you read new stories about stem cell discoveries or clinical trials...
A French biopharma company has announced their plans to carry out human trials of a new treatment that would insert genes from light-seeking algae into the eyes of patients with inherited blindness in order to help them regain sight. The treatment involves optogenetics, a technique that converts nerve cells into light sensitive cells.
jCyte, one of the leaders in developing cell-based therapies for RP, announces positive 12-month results from its Phase 1/2a clinical trial to treat retinitis pigmentosa with stem cells.
Encouraging signs this week that the FDA is serious when it granted Regenerative Medicine Advanced Therapy (RMAT) status to the CIRM-funded jCyte clinical trial for a rare form of blindness. This is a big deal because RMAT seeks to accelerate approval for stem cell therapies that demonstrate they can help patients with unmet medical needs.
Foundation Fighting Blindness Press Release (Columbia, MD) - A Cautionary Tale About the Need to Educate Patients and Advance Research to Produce Treatments with Proven Efficacy, Says Foundation Fighting Blindness
Chimeras are incredibly useful for understanding how animals grow and develop. They might one day be used to grow life-saving organs that can be transplanted into humans.
Foundation Fighting Blindness' deputy chief research officer, Dr. Brian Mansfield, explains how retinal researchers are working with induced pluripotent stem cells (iPSC), a patient's own skin cells, to gain a better understanding of the RP caused by defects in the gene USH2A. This basic research provides critical information for developing future treatments.
Researchers at the University of Wisconsin-Madison developed an innovative process to transform skin cells into retinal cells — cells that hold great promise for restoring vision.
ReNeuron, a stem cell development company in the United Kingdom, is planning to file for regulatory approval in late 2013 to launch a clinical trial of a stem cell treatment for people with retinitis pigmentosa
Researchers in Japan have discovered a way to coax mouse embryonic stem cells into forming an eyelike structure.
For only the second time, the Food and Drug Administration approved a company’s request to test an embryonic stem cell-based therapy on human patients. Advanced Cell Technology (ACT), based in Marlborough, Mass., will begin testing its retinal cell treatment this year in a dozen patients with Stargardt’s macular dystrophy, an inherited degenerative eye disease that leads to blindness in children.
A new stem cell therapy is now available to eye patients using subretinal placement of adult stem cells. Initial patients included an individual with Stargardts Disease and a patient with Age Related Macular Degeneration.
UC Irvine researchers have created a retina from human embryonic stem cells, the first time they've been used to create a three-dimensional tissue structure. The eight-layer, early stage retina could be the first step towards the development of transplant-ready retinas to treat eye disorders, such as retinitis pigmentosa and macular degeneration.
A research team funded by the Foundation Fighting Blindness has used cell transplantation to restore vision in a mouse model of Usher syndrome type 2A. . Never before has a cell-based treatment been used to save vision in an Usher syndrome study, in large part because no other Usher syndrome animal models have exhibited vision loss or retinal degeneration. The advancement is a critical step forward in developing a vision treatment for humans with the condition.
An international research team led by Columbia Univ. Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa.
The man had Limbal Stem Cell Deficiency, which is not genetic, but the technology may be applicable to Usher patients in the future.
The transplantation of stem cells that are capable of producing functional cell types might be a promising treatment for hearing impairment.
This handbook on stem cell therapies was published in 2008 but is still very relevant today.
According to Reuters, stem cells from tiny embryos can be used to restore lost hearing and vision in animals. This research holds promise for humans.
