Abstract: Composition and methods are provided for the specific manipulation of protein tyrosine phosphatase (PTP) activity, including without limitation manipulation of protein tyrosine phosphatase receptor type gamma (PTPRG). The modulation of PTP activity can be performed in vitro or in vivo, and is useful for therapeutic and research purposes. In some embodiments, an effective dose of a PTP modulator is provided to an individual for preventing or treating disease involving dysregulated tyrosine kinase activity and/or signaling mechanisms involving tyrosine phosphorylation and/or tyrosine kinase activity. In other embodiments, a PTP modulator is utilized in the analysis and screening of phosphatase pathways in a cell.
Abstract: The present invention is in the field of stem cell biology, in particular in the field of developmental and regenerative biology. The invention generally relates to a method of generating cells capable of differentiating to a multicellular organoid unit that morphologically and/or functionally resembles the terminal ductal-lobular unit. More precisely, said cells are generated by dissociating mammary epithelial tissue, thereby gaining cells and culturing said cells in presence of a compound which elevates cAMP levels in a collagen gel. Under said culturing conditions said cells form a multicellular organoid unit facilitating to obtain a breast stem cell by isolating a single cell from said multicellular organoid unit. The present invention also relates to enriching said cells and differentiating them to a multicellular organoid that morphologically and/or functionally resembles the terminal ductal-lobular unit and use of said cells or said multicellular organoid in testing a compound.

Abstract: A method of creating a protein rich conditioned medium. The method includes culturing mesenchymal stem cells in a container utilizing a first growth medium, allowing a time period for proliferation of the mesenchymal stem cells until a desired level of confluence is achieved in the container, discarding a supernatant from the container, adding a second medium to the container, incubating the mesenchymal stem cells, and collecting the conditioned medium. The method produces significantly higher quantities of byproducts secreted by the mesenchymal stem cells. Byproducts are usable for wound healing, disease treatment, cosmetic, or other beneficial effects when applied or otherwise delivered to a patient.
Abstract: The invention provides methods and materials for resetting or sustaining a human stem cell in a “naïve” or “ground” state, based on the use of media including combinations of inhibitors. An example naïve culture medium comprises a PKC inhibitor, a MEK inhibitor. Also provided are methods of obtaining or propagating such cells, cells obtained using these methods, and novel culture media, which can be used in these methods.

Abstract: A method for detecting a presence or an absence of at least one zone of inhibition, the method including a step consisting in depositing a volume of the sample in liquid form along a deposition zone extending along an axis at the surface of the agar culture medium and a step consisting in depositing a determined amount of a chemical agent at the surface of the agar culture medium, the deposit defining a potential zone of inhibition, the axis of the zone of deposition of the sample intersecting the potential zone of inhibition.
Abstract: Provided is a method for efficiently and stably separating cells having a high biological activity from a biological tissue, by using a degrading-enzyme composition, which is prepared by adding an enzyme for degrading a major protein of the biological tissue in an amount determined depending on the composition of the major protein to a predetermined amount of a neutral protease and/or a protease derived from Clostridium sp. According to this method, the type and amount of protein-degrading enzyme to be used for isolating cells can be determined from the composition of a major protein of the biological tissue. Thus, cells having a high biological activity can be efficiently separated while reducing the amount of protein-degrading enzyme to be used.

Abstract: Provided is a hair growth-promoting composition comprising: 100 parts by weight of a stem cell culture solution obtained from a culture medium of mesenchymal stem cells which have been subcultured two or more times; 0.001 to 0.1 parts by weight of zinc; 5 to 50 parts by weight of a panthenol based compound; and 0.0001 to 0.1 parts by weight of a water-soluble vitamin, wherein it is sprayed or applied on the scalp to promote hair growth. Said hair growth-promoting composition may have an excellent effect and improve economical efficiency in treating alopecia due to a simple delivery method of the composition.
Abstract: The present invention relates to a composition for alcohol or acetaldehyde degradation, which comprises probiotics. The composition of the present invention has a significant synergistic effect on the degradation of alcohol or acetaldehyde, when the probiotics are administered alone or in combination or the composition further comprises excipients. In addition, the composition according to the present invention may effectively degrade alcohol and acetaldehyde, thereby not only treating or preventing alcohol-induced diseases, but also effectively relieving hangovers caused by excessive drinking.
Abstract: Herein is reported a feed mixing device for adding feed solutions with a non-physiologically pH value to a cell cultivation vessel comprising a chamber for mixing the feed solutions prior to their addition to the cell cultivation vessel as well as its use. With the feed mixing device as reported herein feed components can be provided in solution at a pH value at which they have good solubility and/or good stability whereby the pH value can be clearly different from the pH value of the cultivation medium, i.e. different from the physiological pH value. This allows performing the cultivation with more flexibility compared to a cultivation in which the pH value of the feed solution is limited to a small range around the pH value of the cultivation.
