    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: 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.
