Cell type-specific expression profile and signaling requirements in early hematopoietic reprogramming.

ABSTRACT: Hematopoietic cells represent an attractive starting cell type for induced pluripotent stem (iPS) cells induction, yet the molecular mechanisms in hematopoietic reprogramming are poorly defined. In this study, we showed that long-term hematopoietic stem cells are more amenable for iPS cells induction among several hematopoietic stem and progenitor cell (HSPC) populations, and that this is accompanied by an earlier induction of the transcriptional program that is involved in the promotion of macromolecule metabolism and cell proliferation. Notably, we identified multiple signaling pathways that exhibited distinct expression patterns in HSPCs compared to that of fibroblasts, which is the most commonly used model for probing the somatic reprogramming process. We further experimentally confirm
