Recent evidence suggests the existence of progenitor cells in adult tissues that are capable of differentiating into vascular structures as well as
into all hematopoietic cell lineages.
Since then he has continued to investigate new strategies to overcome the major hurdles to safe and effective gene transfer, translate then into new therapeutic strategies for genetic disease and cancer, and allowed new insights
into hematopoietic stem cell function, induction of immunological tolerance and tumor angiogenesis.
Instead, they show the expression of certain genes and DNA methylations were better indicators of the efficiency at which a cell line could be differentiated
into the hematopoietic lineage.
The researchers show that higher expression of the growth hormone IFG2, or insulin - like growth factor 2, is indicative of iPS cells initiating their conversion
into hematopoietic cells.
