Disclosed are novel cellular compositions of matter and treatment means for generation of universal donor regenerative T cells by exposure to mesenchymal stem cells or supernatant derived thereof. In one embodiment, regenerative T cells are created by differentiation of pluripotent stem cells in the presence of supernatant generated from activated mesenchymal stem cell population. The invention provides for creation of T cells which are capable of endowing regenerative activity, and/or anti-inflammatory, and/or angiogenic activity.

Provided are novel serum-free culture media which comprise basic fibroblast growth factor (bFGF), transforming growth factor beta-3 and ascorbic acid at a concentration of at least about 50 microgram/ml; ascorbic acid at a concentration range of about 400-600 microgram/ml, bFGF at a concentration range of about 50-200 ng/ml, xeno-free serum replacement and a lipid mixture; the IL6RIL6 chimera at a concentration range of about 50-200 picogram per milliliter (pg/ml); or leukemia inhibitory factor (LIF) at a concentration of at least 2000 units/ml; cell cultures comprising same with pluripotent stem cells such as human embryonic stem cells and induced pluripotent stem (iPS) cells, and methods of using same for expanding pluripotent stem cells in an undifferentiated state using two-dimensional or three-dimensional culture systems; and methods of expanding iPS cells in a suspension culture devoid of substrate adherence and cell encapsulation.

The present invention provides compositions and methods for the culture and maintenance of pluripotent stem cells. More particularly, the present invention provides for compositions and methods for culturing, maintaining, growing and stabilizing primate pluripotent stem cells in a feeder-free defined media further comprising human serum, or a soluble attachment component of the human serum, for promoting cell attachment.

The present application discloses a method for inducing cells to gain characteristics of nave stem cell state comprising culturing the cells in the presence of a MUC1* activator.

The present application provides non-naturally occurring 3D brown adipose-derived stem cell (BADSC) aggregates, methods of making the 3D BADSC aggregates, and methods of using the 3D BADSC aggregates.

Methods of developing and using cell lines, such as stem cell lines, for therapeutic or cosmetic use. In one embodiment, the cell lines are used to treat a wide range of degenerative and metabolic disorders including, but not limited to, obesity, diabetes, hypertension, and cardiac deficiency. Also described are methods of using such cell lines to screen for compounds that play a role in regulating a variety of processes.

The present disclosure relates to the use of laminin-521 in obtaining retinal pigment epithelium (RPE) cells. Pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in totally defined and xeno-free conditions. A first cell culture medium contains a growth factor, and a second cell culture medium does not contain growth factor. The stem cells are first exposed to the first cell culture medium, then exposed to the second cell culture medium for a longer time period. After a number of weeks, clinical grade RPE cells are obtained from the stem cells.

Provided are novel serum-free culture media which comprise basic fibroblast growth factor (bFGF), transforming growth factor beta-3 and ascorbic acid at a concentration of at least about 50 microgram/ml; ascorbic acid at a concentration range of about 400-600 microgram/ml, bFGF at a concentration range of about 50-200 ng/ml, xeno-free serum replacement and a lipid mixture; the IL6RIL6 chimera at a concentration range of about 50-200 picogram per milliliter (pg/ml); or leukemia inhibitory factor (LIF) at a concentration of at least 2000 units/ml; cell cultures comprising same with pluripotent stem cells such as human embryonic stem cells and induced pluripotent stem (iPS) cells, and methods of using same for expanding pluripotent stem cells in an undifferentiated state using two-dimensional or three-dimensional culture systems; and methods of expanding iPS cells in a suspension culture devoid of substrate adherence and cell encapsulation.

The present invention relates to production of therapeutic potential WJ-MSCs for clinical purposes. The WJ-MSCs cultured in optimal culture conditions for production of clinical grade WJ-MSCs wherein 4 different culture media which are Media A, Media B, Media C and Media D used to produce 4 types of WJ-MSCs with different therapeutic potential. The WJ-MSCs harvested from Media A has therapeutic potential related to immune, wound healing and cell migration and the WJ-MSCs harvested from Media B has therapeutic potential related to localization, cell proliferation and cell migration. Meanwhile, the WJ-MSCs harvested from Media C has therapeutic potential related to organ development and osteogenesis and the WJ-MSCs harvested from Media D has therapeutic potential related to tissue development, cell signaling and localization.

Compositions and processes for culturing human stem cells in vitro in an undifferentiated state are disclosed. In this regard, human embryonic stem cells proliferated and maintained their pluripotency when cultured on plates coated with recombinant laminin-10 (laminin-511).
