Abstract
Embodiments provide methods and apparatus for fabricating blood products, such as platelet-rich plasma, containing elevated concentrations of growth factors such as platelet derived growth factor. The platelet-rich plasma can be autologous, and the concentration of growth factors (e.g., platelet derived growth factor) is elevated relative to other samples isolated from the same subject. The platelet-rich plasma can be used to promote tissue regeneration, including wound healing, joint repair, hair growth, and the like. The compositions can be combined with stem cells and used to treat disorders otherwise treated with stem cells. The growth factors present in the samples can direct the differentiation of the stem cells.
