摘要:
The present disclosure relates to methods and compositions using RAP, a derivative of RAP, a variant of RAP, or a fragment of RAP to inhibit LRP1, a myelin debris receptor. The methods and compositions involve increasing, promoting, restoring, and/or enhancing differentiation of oligodendrocyte progenitor cells, myelin protein expression, mature oligodendrocyte marker expression, and/or myelination. The methods and compositions disclosed herein inhibit or block pathological activation of RhoA in OPCs. The methods and compositions also involve alleviating one or more symptoms of MS and treating MS, including slowing or stopping MS progression.
摘要:
The invention provides a differentiation protocol to generate retinal pigmented epithelial cells (RPECs) for the in vitro differentiation of mammalian pluripotent stem cells to mature, functional retinal pigment epithelial cells (RPEC). A culture system is described that uses defined medium comprising xeno-free optimal combinations of small molecule agonists and antagonists where: (a) pluripotent stem cells are cultured in the absence of feeder cells, serum, or conditioned medium; (b) defined culture conditions is used to obtain an eye-field cell (EFC) population; (c) whereby EFC are subsequently differentiated to RPEC when exposed to culture medium containing small molecule agonists thus producing highly homogenous RPEC; and (d) cultured under optimal conditions until maturation, through stimulation via activin-like signalling through addition of either cyclic AMP or cyclic AMP inducers to produce complete monolayer formation within 21 +7 days. An alternate differentiation procedure also takes EFC intermediates prepared above into photoreceptors.
摘要:
The present disclosure provides novel cell compositions engineered to express at least a chimeric antigen receptor and a survival factor. Methods of using such cell compositions are also described.
摘要:
The present invention relates to the use of dermatopontin (DPT) or a functional fragment thereof for the maintenance of hematopoietic stem and/or progenitor cells in culture. The present invention further relates to a method for maintaining hematopoietic stem and/or progenitor cells in culture, the method comprising culturing the hematopoietic stem and/or progenitor cells in the presence of dermatopontin (DPT) or a functional fragment thereof. Furthermore, the present invention relates to a cell culture medium for the maintenance of hematopoietic stem and/or progenitor cells, wherein the cell culture medium comprises a medium and dermatopontin (DPT) or a functional fragment thereof and further optionally comprises serum/serum replacement, (a) reducing agent(s), and/or (an) antibiotic(s) as well as a kit comprising dermatopontin (DPT) or a functional fragment thereof and at least one of: (a) (a) cell culture medium; (b) one or more cytokines; (c) serum/serum replacement; (d) (a) reducing agent(s), and/or (e) (an) antibiotic(s).
摘要:
Disclosed herein are universal donor stem cells and related methods of their use and production. The universal donor stem cells disclosed herein are useful for overcoming the immune rejection in cell-based transplantation therapies. In certain embodiments, the universal donor stem cells disclosed herein do not express one or more MHC-I and MHC-II human leukocyte antigens. Similarly, in certain embodiments, the universal donor stem cells disclosed herein do not express one or more human leukocyte antigens (e.g., HLA-A, HLA-B and/or HLA-C) corresponding to MHC-I and MHC-II human leukocyte antigens, thereby rendering such cells hypoimmunogenic.
摘要:
This disclosure relates to growth media and environments for in vitro culturing of cells that produce or are capable of producing antibodies. In certain embodiments, the media comprises IL-6, fibronectin, and typically a saccharide. In certain embodiments, the disclosure contemplates cell culture compositions comprising IL-6 and fibronectin that are derived from proteins secreted from mesenchymal stromal/stem cells (MSCs). In certain embodiments, the disclosure contemplates enclosures comprising culture compositions disclosed herein that are in ambient air or optionally in an environment wherein oxygen is absent or at a low concentration.
摘要:
The present invention describes methods for long-term culturing of ER pos cells, cell lines, and/or cell strains with extended lifespan and/or cell strain as well as culture medium compositions. The invention further describes methods for isolating cells which may be used as starting point for long-term culturing of ER pos cells, cell lines, and/or cell strains with extended lifespan and/or cell strain. The invention further discloses various methods for generating ER pos tumorigenic cells, cell lines, and/or cell strains with extended lifespan and/or cell strain as well as various assays for their use.
