The present invention relates to methods for producing an induced pluripotent stem (iPSC), the method comprising the following steps in order: culturing a somatic cell in a first culture condition adapted to promote the reprogramming of the cell towards a pluripotent state; culturing the cell in a second culture condition adapted to promote a hypomethylated DNA state in the cell; and culturing the cell in a third culture condition adapted to promote a primed pluripotent state, thereby producing an iPSC from a somatic cell. The invention also relates to cells and compositions resulting from those methods.

Disclosed are novel means, protocols, and compositions of matter for eliciting an immune response against blood vessels supplying neoplastic tissue. In one embodiment pluripotent stem cells are transfected with one or more genes capable of eliciting immunity. In some embodiments such genes are engineered under control of specific promoters to allow for various specificities of activity. In one specific embodiment pluripotent stem cells engineered to endow properties capable of inducing expression of the α-Gal epitope (Galα1,3Galα1,4G1cNAc-R).

Methods and compositions for rapid development of reporter lines utilizing safe harbor sites in iPSCS, as well as other progenitor cells, pluripotent and multipotent stem cells and differentiated cells, and multiple Lox sites are provided.

Methods are disclosed herein for producing human hepatocytes from human induced pluripotent stem cells. Also provided are transgenic rats for the expansion of human hepatocytes, such as those produced using the methods disclosed herein.

Compositions and methods for generating insulin-producing beta cells from pluripotent stem cells are provided. The compositions and methods of the present invention involve stepwise differentiation while the differentiating cells are cultured on a lung tissue-derived acellular scaffold.

This invention generally relates to a novel RNA composition and its production method useful for generating and expanding induced pluripotent stem cells (iPS cells; iPSC) as well as adult stem cells (ASC). The RNA composition so defined can be used for producing not only non-transgenic but also tumor-free iPS cells. The defined RNA composition contans at least two types of different RNA constructs; one is “miR-302 precursor RNA (pre-miR-302)” and the other is “RNA-dependent RNA polymerase (RdRp)” mRNA. Both of pre-miR-302 and RdRp mRNA contain highly structured RNA comformations, such as hairpin and stem-loop structures. To produce highly structured RNAs, a novel PCR-IVT methodology has been developed and used with a specially designed RNA polymerase-helicase mixture activity.

The present invention relates to a pharmaceutical composition for preventing or treating renal diseases, comprising, as an active ingredient, exosomes isolated from precursor cells of induced pluripotent stem cell-derived mesenchymal stem cells, the precursor cells having been treated or not having been treated with a pretreatment material. Exosomes of the present invention exhibit an effect of preventing or treating renal diseases that is more improved than that of exosomes isolated from conventional mesenchymal stem cells, thereby being effectively usable for relevant research and development and productization.

The present invention relates to methods for reprogramming somatic cells into pluripotent stem cell-like cells. Such cells may express pluripotency inducing genes including Oct4, Nanog and Sox2 without introducing exogeneous genes, proteins, or chemicals. The discovery that the inhibition of mechanosensitive and stretch-activated ion channels in somatic cells specifically activates pluripotency inducing factor genes inspired the cell reprogramming culture methods in which somatic cells were incubated with the inhibitor, GsMTX4, against mechanosensitive and stretch-activated ion channels, cultured on the soft hydrogel surface, or treated with cholesterol depletion substance, methyl-beta-cyclodextrin (MβCD). Described methods produce pluripotent stem cell-like cells and subsequently re-differentiated cells, which include adipocytes, osteocytes, neuronal cells. Methods may be combined to increase the efficiency of the somatic cell reprogramming A somatic cell reprogramming kit was also created with tissue culture dishes casted with hydrogel (dehydrated) and MβCD.

A method of treating medical conditions by stem cell therapy. Stem cells are transplanted into and onto a human or animal patient in need, Then stem cell proliferation is increased, activating migration to sites of inflammation and epigenetic effects, regenerating damaged tissues through inhibition of apoptosis, inhibition of inflammation and oxidative stress, and inducing angiogenesis and stem cell differentiation into various cells by administering substances that induce GSK-3 beta inhibition and HDAC inhibition.

A first terminal determines a collection date of a somatic cell based on a desired collection date and a collectable date transmitted by a second medium; and outputs the collection date to a first medium. A second terminal outputs the collectable date to the second medium; and determines an acceptance date based on the collection date transmitted by the first medium and a production period of an iPS cell transmitted by a third medium. A third terminal determines the production period based on the collection date and a producible period, and determines a shipment date based on the production period and stockable location and period transmitted by a fourth medium; and outputs the production period to the third medium. A fourth terminal outputs the stockable location and period to the fourth medium; and determines stock location and period based on the production period and the stockable location and period.
