Method of de-differentiating and re-differentiating somatic cells using RNA

RNA prepared by in vitro transcription using a polymerase chain reaction (PCR)-generated template can be introduced into a cell to modulate cell activity. This method is useful in de-differentiating somatic cells to pluripotent, multipotent, or unipotent cells; re-differentiating stem cells into differentiated cells; or reprogramming of somatic cells to modulate cell activities such as metabolism. Cells can also be transfected with inhibitory RNAs, such as small interfering RNA (siRNA) or micro RNA (miRNA), or combinations thereof to induce reprogramming of somatic cells. For example, target cells are isolated from a donor, contacted with one or more RNA's causing the cells to be de-differentiated, re-differentiated, or reprogrammed in vitro, and administered to a patient in need thereof. The resulting cells are useful for treating one or more symptoms of a variety of diseases and disorders, for organ regeneration, and for restoration of the immune system.

Technologies, Methods, and Products of Small Molecule Directed Tissue and Organ Regeneration from Human Pluripotent Stem Cells

Pluripotent human embryonic stem cells (hESCs) hold great potential for restoring tissue and organ function, which has been hindered by inefficiency and instability of generating desired cell types through multi-lineage differentiation. This instant invention is based on the discovery that pluripotent hESCs maintained under defined culture conditions can be uniformly converted into a specific lineage by small molecule induction. Retinoic acid induces specification of neuroectoderm direct from the pluripotent state of hESCs and triggers progression to neuronal progenitors and neurons efficiently. Similarly, nicotinamide induces specification of cardiomesoderm direct from the pluripotent state of hESCs and triggers progression to cardiac precursors and cardiomyocytes efficiently. This technology provides a large supply of clinically-suitable human neuronal or cardiac therapeutic products for CNS or myocardium repair. This invention enables well-controlled efficient induction of pluripotent hESCs exclusively to a specific clinically-relevant lineage for tissue and organ engineering and regeneration, cell-based therapy, and drug discovery.
