Episomal vector-based generation of human induced pluripotent stem cell line MUSIi020-A from peripheral blood T-cells.

Human induced pluripotent stem cell (iPSC) line MUSIi020-A was generated from T cells isolated from peripheral blood of a healthy 37-year-old female and reprogrammed using episomal plasmid vectors. The established transgene-free MUSIi020-A, which retained a normal karyotype, displayed pluripotency as characterized by expression of pluripotency markers and by in vitro spontaneous differentiation toward three embryonic germ layers. This cell line may represent a valuable tool for studying T cell development and a potential cell source for cancer immunotherapy.

Induced Pluripotent Stem Cells as a Tool for Modeling Hematologic Disorders and as a Potential Source for Cell-Based Therapies.

The breakthrough in human induced pluripotent stem cells (hiPSCs) has revolutionized the field of biomedical and pharmaceutical research and opened up vast opportunities for drug discovery and regenerative medicine, especially when combined with gene-editing technology. Numerous healthy and patient-derived hiPSCs for human disease modeling have been established, enabling mechanistic studies of pathogenesis, platforms for preclinical drug screening, and the development of novel therapeutic targets/approaches. Additionally, hiPSCs hold great promise for cell-based therapy, serving as an attractive cell source for generating stem/progenitor cells or functional differentiated cells for degenerative diseases, due to their unlimited proliferative capacity, pluripotency, and ethical acceptability. In this review, we provide an overview of hiPSCs and their utility in the study of hematologic disorders through hematopoietic differentiation. We highlight recent hereditary and acquired genetic hematologic disease modeling with patient-specific iPSCs, and discuss their applications as instrumental drug screening tools. The clinical applications of hiPSCs in cell-based therapy, including the next-generation cancer immunotherapy, are provided. Lastly, we discuss the current challenges that need to be addressed to fulfill the validity of hiPSC-based disease modeling and future perspectives of hiPSCs in the field of hematology.
