Marrow-nucleated cells are used every day in regenerative orthopedics. The knee microfracture surgery technique relies on the release of these cells into a cartilage lesion to initiate fibrocartilage repair in osteochondral defects. [13] In addition, this cell population has also been shown to assist in the repair of non-union fractures. [14]
Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
A 2017 review described the evidence as moderate for knee osteoarthritis. [15] A 2016 review found benefit but there was a moderate degree of variability between trials and risk of bias. [16] In 2019, the American College of Rheumatology recommended against prolotherapy for knee osteoarthritis. [17]
In 2021, stem cell injections in the US have caused grave infections in at least 20 patients who received umbilical cord blood-derived products marketed as "stem cell treatment". [79] In 2023, the case of a woman who was infected with Mycobacterium abscessus and sustained meningitis after stem cell treatment for multiple sclerosis at a ...
Per the report, the Minnesota Timberwolves center received stem cell and platelet-rich plasma injections in both knees, his left wrist, left ankle and right finger on Friday.
Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
