Abstract

Disclosed in the present application are a polypeptide having a novel sequence and a composition and method for culturing feeder-free embryonic stem cells, using the same. The composition and method according to the present application allows for xeno-free cultivation and for long proliferation of embryonic stem cells in an undifferentiated state with differentiation potency retained therein.

Abstract

The present invention provides a method for improving traits in a plant, like e.g. improving yield-related traits like number of flowers, number of siliques, seed yield, stem growth in a plant, the method comprising disruption of endogenous ROCK1 gene in a plant cell, wherein said disruption inhibits expression and/or activity of a product of said endogenous ROCK1 gene compared to a corresponding control plant cell lacking such a disruption.


Abstract

The presently disclosed subject matter focuses on recapitulating the heterotypic interactions needed to maximize the co-development of vasculature and bone. More particularly, the presently disclosed subject matter explores the potential of cellular aggregation and temporal presentation of factors to induce the cell-cell signaling events required to stimulate ASCs to self-organize into vascularized bone. Further, exogenous PDGF-BB synergizes complex tissue formation in ASC cultures by enhancing vascular stability and osteogenic differentiation. The presently disclosed approach provides a robust protocol to engineer vascularized bone with ASCs in vitro.

Abstract

A set of target peptides are presented by HLA A* 0201 on the surface of ovarian cancer cells. They are envisioned to among other things (a) stimulate an immune response to the proliferative disease, e.g., ovarian cancer, (b) function as immunotherapeutics in adoptive T-cell therapy or as a vaccine, (c) facilitate antibody recognition of tumor boundaries in surgical pathology samples, (d) act as biomarkers for early detection and/or diagnosis of the disease, and (e) act as targets in the generation antibody-like molecules which recognize the target-peptide/MHC complex.


Abstract

Coronatine has been found to enhance binding of the JAZ1 degron to the Arabidopsis F-box protein COI1, and analysis of the JAZ1 degron sequence has resulted in the identification of specific peptide sequences that bind COI1 with high affinity in the presence of coronatine. Crystal structure analysis has determined that coronatine and JA-Ile enhance the interaction between COI1 and JAZ1 via binding to a specific binding pocket on COI1. Attachment of one or more JAZ1 peptide tags as disclosed herein to a target protein in a non-plant cell expressing Arabidopsis COI1 or a homolog thereof results in degradation of the target protein following addition of a molecule that binds the coronatine/JA-Ile binding pocket on COI1. Therefore, provided herein are compositions, methods, and kits for targeted protein degradation.


Abstract

The present invention provides a ceramic porous body for in-vitro and in-vivo use comprising a composition comprising a calcium aluminate (CA) containing phase and optionally at least one of an accelerator, a retarder, a surfactant, a foaming agent, a reactive alumina, water, a fiber, and a biologically active material, and combinations thereof. Ceramic compositions are provides as well as method of using the ceramic compositions and methods of manufacturing a ceramic porous body. The ceramic porous bodies of this invention may be used as artificial bones, joints, in-vitro support structures, and in-vivo support structures for cells, tissues, organs, and nerve growth and regeneration.

Abstract

Methods for enhancing the generation of primordial germ cells in pluripotent embryonic cells by contacting the pluripotent cells with at least one 60A class BMP protein and at least one DPP class BMP protein are provided. Also provided are methods for treating sterility and for the introduction of at least one transgene into the germ line of an animal.


Abstract

The present invention relates to a composition including Otx2 protein as an active ingredient for preventing and treating mitochondria dysfunction diseases. In particular, a single defect of the Otx2 gene reduces the visual function and electroretinogram (ERG) reaction, causes degeneration and decline of development of a cone photoreceptor and bipolar cells, and causes serious degeneration of type-II off-cone bipolar cells in particular. Also, the composition including Otx2 protein as an active ingredient of the present invention is confirmed to be usefully used for preventing and treating mitochondria dysfunction diseases by confirming that the Otx2 protein injected into an eyeball of Otx2 anisogamy mutant mouse passes through retinal nerve cells and significantly controls the activity of mitochondria.
