Bone marrow is categorized as a biological treatment that can be autologous (from self) or allogenic (from others). We use bone marrow from your own body. Bone marrow is full of many growth factors and bioactive proteins that are intimately involved in the healing process. Bone marrow also contains stem cells, which have the unique ability to divide into other cell types. The stem cells of most interest to us are the medicinal signaling cells (MSCs) in the bone marrow that possess the potential to guide and direct the healing process in a way that would be similar to how a head football coach leads his team. The stem cells can secrete bioactive proteins and also stimulate neighboring cells to participate in the healing process.
