Osaka Metropolitan University researchers have pioneered a novel technique to generate high-quality mesenchymal stem cells (MSCs) from canine induced pluripotent stem cells (iPSCs). By reprogramming diverse canine somatic cell types—including urine-derived cells—into iPSCs and differentiating them into MSCs, the method circumvents limitations of traditional MSC sources, which suffer from donor variability and restricted proliferation. This advancement promises more consistent regenerative therapies in veterinary medicine and translational models, expanding the potential for treating canine diseases through immunomodulation and tissue repair with standardized stem cell populations.
