Caution urged over ‘miracle’ of equine stem cell therapy
Clinical credence of stalk prison theatre cellular telephone therapy has greatly outpaced the scientific evidence, an skillful suggests.
Dr Wesley Sutter, a surgical orthopedic specialist at Lexington Equine Surgery & Sports Medicine, in Kentucky, was commenting on the ascension of equine stalk prison theatre cellular telephone therapy inward the July number of Gluck Equine Disease Quarterly.
Sutter, whose expertise has seen him speak nationally in addition to internationally on regenerative medicine therapies inward the equine athlete, referred to a recent idiot box documentary nearly stalk prison theatre cellular telephone fraud inward human medicine.
It posed the question: “Are stalk cells the ‘snake oil’ of the 21st century?”
“The documentary focused on the growing, highly lucrative job organisation of simulated stalk prison theatre cellular telephone cures that reportedly resulted inward a federal investigation,” Sutter noted.
“With world awareness of failures inward stalk prison theatre cellular telephone therapy newly heightened, it is of import to reverberate on our province of affairs inward equine medicine.”
Sutter said stalk prison theatre cellular telephone treatments for horses remove maintain been available since at to the lowest degree 2005.
“They remove maintain locomote a relatively mutual handling for many equine musculoskeletal injuries, oft promoted equally a panacea for bone, cartilage, in addition to tendon healing.
“Internet testimonials in addition to videos claiming miraculous cures inward private patients with neurologic in addition to laminitic weather remove maintain fueled oft irrational exuberance in addition to extravagant expectations.
“To date, no published controlled clinical studies present efficacy inward operate of stalk prison theatre cellular telephone handling for whatsoever of the weather beingness treated.
“In fact, the ii most recent studies evaluating stalk cells, 1 inward a tendonitis model in addition to the other inward a cartilage defect model, showed no pregnant divergence with their use, either clinically or histologically, equally compared to controls inward which stems cells were non used.
“Papers remove maintain touted stalk cells’ miraculous mightiness inward the laboratory; however, 1 time administered to the patient, the province of affairs changes dramatically. H5N1 multitude of poorly understood factors probable mitigate the action of stalk cells 1 time administered.
“Patients remove maintain their ain stalk cells, in addition to injure healing is modulated through a complex array of molecular events, including cytokine signaling. Equally important, stalk prison theatre cellular telephone culturing methods in addition to rootage tissues (bone marrow, adipose, fetal cells, in addition to cord blood) vary alongside laboratories.
“Are stalk cells from whatsoever rootage goodness for everything? Most scientists would concur this is unlikely, in addition to hereafter handling volition probable involve pick of stalk cells with a item phenotype or genetic modification inward social club to process a specific disease.
“The most basic questions remain. How produce nosotros know that the stalk cells from a item laboratory or procedure are non terminally differentiated fibroblasts that remove maintain absolutely no biologic effect? How produce nosotros know they volition persist inward the injure surroundings long plenty to remove maintain a biologic effect? How produce nosotros know they are of the right phenotype?
“Plasticity, differentiation into the desired tissue type, and/or feeder effects may live acquaint inward the petri dish; however, mechanisms 1 time injected into the patient remove maintain yet to live elucidated.
“With a virtual absence of oversight in addition to regulations, equine veterinarian operate of stalk cells has dramatically increased, resulting inward over a dozen university, private enterprise, in addition to private practices culturing allogeneic and/or autologous stalk cells for operate inward horses,” Sutter said.
“Expert opinion, testimonials, in addition to anecdotal prove are non inward brusk supply.
“When coupled with a lack of goodness clinical prove or fifty-fifty a goodness agreement of potential mechanisms, they threaten to draw stalk prison theatre cellular telephone therapies into the abyss oft occupied past times nutraceuticals in addition to supplements.
“Stem cells handgrip promise. However, clinical credence has greatly outpaced the scientific evidence. That prove needs to live supplied, with both professional person organizations in addition to those producing stalk cells taking the lead.
“Practitioners using stalk cells also remove maintain a responsibleness to accurately correspond these therapies to their clients.”
