The present disclosure relates to a composition for increasing the biological activity of stem cells using mixture 4F. Stem cells treated with mixture 4F according to the present disclosure not only acquire undifferentiated characteristics (stemness), but also have the advantage of improving cell proliferative ability and mobility, and thus, after being transplanted into a body, the stem cells can improve cell survival and engraftment and further enhance the ability to regenerate blood vessels and tissues. Accordingly, the stem cells can have various applications in the fields of stem cell differentiation and ischemic disease prevention or treatment.

An aqueous cell culture medium composition includes an aqueous cell culture solution configured to support the culture of mammalian cells. The composition further includes a synthetic polymer conjugated to a polypeptide dissolved in the aqueous cell culture solution. The synthetic polymer conjugated to a polypeptide is configured to attach to the surface of a cell culture article under cell culture conditions. Incubation of the aqueous cell culture medium composition on a cell culture surface under cell culture conditions results is attachment to the surface of the synthetic polymer conjugated to the polypeptide.

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.

The present application discloses a cell culture media for growth, maintenance and induction of reversion to a less mature state of a cell comprising a MUC1* activating ligand.

The present invention relates to methods of enhancing transfection in cell culture media supplemented with a plant-produced recombinant mammalian transferrin supplement, as well as kits, and methods of using the supplemented cell culture media to improve growth characteristics of cultured cells for transfection.

Methods and compositions for expanding dopaminergic neuron progenitor cells are described herein that include use of compositions and culture media that have at least the following components: an FGF, an agonist of SHH signaling, an agonist of canonical Wnt signaling, and Wnt-C59. The methods include contacting dopaminergic neuron progenitor cells with a culture medium comprising an FGF, an agonist of SHH signaling, an agonist of canonical Wnt signaling, and Wnt-C59, to generate an expanded dopaminergic neuron progenitor cell population.
