  报告简介:

  Direct cell reprogramming or transdifferentiation, where adult cells are reprogrammed from one lineage to another without going through an intermediate stem cell-like stage, produces cells promising for regenerative medicine. It obviates the use of embryos and minimizes the risk of teratoma formation associated with the in vivo application of induced pluripotent stem cells. Direct reprogramming may offer advantages in tissue-chip development for disease modeling and drug screening because of savings in time and cost. I will discuss our recent effort to convert human endothelial progenitors (hEPC) into induced smooth muscle cells (iSMC), hEPC into induced skeletal myocytes (iSkM), human fibroblasts into induced cardiomyocyte-like cells (iSML), and murine fibroblasts into induced neurons (iN). I will describe various approaches of achieving direct cell reprogramming using transcription factor overexpression, microRNA delivery, molecular pathway manipulation, and CRISPR/dCas9-based transactivation either separately or in combination. This will be presented from the perspective of how biomaterials and biomedical engineering researchers can help advance this exciting field.
