Autologous cells are considered to be the best choice for use in transplantation therapy. However, the challenges and risks associated with the harvest of transplantable autologous cells limit their successful therapeutic application. The current study explores the possibility of isolating neural progenitor cells from circulating multipotent adult progenitor cells for potential use in cell-based and patient-specific therapy for neurological diseases. To enable the selection of neural progenitor cells from human peripheral blood mononuclear cells, and to support their lineage maintenance, the composition of a fibrin-based niche was optimized. Morphological examination and specific marker analysis were carried out, employing a qualitative/quantitative polymerase chain reaction followed by immunocytochemistry to:(i) characterize neural progenitor cells in culture;(ii) monitor proliferation/survival; and (iii …
