The answer is… not exactly. 🧠 Mesenchymal stem cells (MSCs)—which are commonly derived from bone marrow or fat tissue—may help reduce inflammation and improve pain/function in arthritic joints. That part is supported by some human research. 💡 But here’s the important distinction: ❌ We do NOT currently have strong evidence that MSC injections reliably regrow normal, native hyaline cartilage in humans. 📕In some studies, patients may form small amounts of “cartilage-like” tissue, but it’s often fibrocartilage—which is not the same durable cartilage you were born with. So while mesenchymal stem cells may help “calm down” a joint environment… 👉 they are not a proven way to fully reverse arthritis or rebuild a worn-out knee. 👉 The science is promising….but we’re not there yet. #stemcells #cartilage #osteoarthrit...
