CT is genetic correction of autologous HSCs, to overcome donor availability & immune side effects. This Book reviews the progress made on additive gene therapy approaches & the current state of the field. Finally, targeted genetic correction is emerging as a novel therapeutic strategy in the hemoglobinopathies. Although ideal, the inefficiency of targeted correction was rate limiting for translation of this technology to the clinic. With advancements in zinc finger nucleases and TALE endonuclease mediated targeted correction, correction frequencies in hematopoietic stem cells is now reaching levels that may become clinically relevant. Furthermore, the ability to generate autologous embryonic stem cell like cells from primary somatic cells (skin fibroblasts or hematopoietic cells) of the affected individual has allowed for the potential application of genetic correction strategies.This Book reviews upcoming genetic strategies to reactivate fetal hemoglobin production and research advances. weiterlesen
