Good afternoon. I wanted to learn more about stem cells. Tell me where I can read about it

My uncle was fishing by the lake, and my knee ached walking over. Wanted to look up new ways to handle knee pain. Found https://ways2well.com/blog/revolutionizing-knee-pain-treatment-with-stem-cell-therapy-advances and it’s got stem cell stuff. It dives into how it helps, plus things like single doses or longer therapy that can cut swelling and fix joints, written real clear. I liked how it opened my eyes to something different.
