Abstract: The shortage of bone marrow donors and the high risk of allogenic
transplant rejection have prompted investigation into alternative therapeutic
approaches for patients with aplastic anemia. Reconstitution of hematopoietic
function using stem cells derived from cord blood is a promising alternative
which however, the limited number of stem cells obtained restricts clinical
application. In the earlier study, researchers demonstrated the epigenetic reprogramming
of mouse skin fibroblasts into multipotent cells using a transient in vitro
method. After transient reprogramming, cells expressed reprogramming factors
(Oct-3/4, Nanog and Sox-2) and formed teratomas in nude mice. In this study,
PBMCs from aplastic anemia patients were reprogrammed using the transient in
vitro method. Reprogrammed cells (iMS cells) were capable of differentiating
into hematopoietic cells; iMS cells transplanted into lethally irradiated mice
differentiated into bone marrow and splenic cells. Results indicate that reprogrammed
PBMCs are multipotent and can restore hematopoietic function.
