Regenerative Medicine

Implanted materials may eventually help injuries heal more completely with less scarring. Exosomes are distinguished from stem cells, though their biological differences are not deeply explained. The rotator cuff stem-cell recovery story is presented as anecdotal rather than controlled evidence. Regenerative therapies can slow tissue degradation and support restoration, but additional research is needed to fully characterize safety and durability. Underwater treadmill therapy supports gait retraining by reducing load while preserving walking practice. Dr. Kaitlin Sadler has worked on materials intended to guide the immune system toward regeneration. PRP therapy uses concentrated growth factors from the patient's own blood to stimulate tissue healing. Helper T cells are highlighted as important immune cells for wound healing. Electroacupuncture is proposed to reduce inflammation, improve blood flow, decrease spasm, and reduce pressure around the spinal cord. Intrathecal delivery is described as a way for cells or signals to circulate through cerebrospinal fluid and potentially reach the brain and spinal cord. Regenerative substances may modulate inflammation in neurodegenerative di…
