A non-degradable device for use in controlled feeding of mammalian cell cultures including by way of example cultures of stem cells such as induced pluripotent stem cells (iPSCs). Methods of making and using the device are also disclosed.

The present invention relates to methods of upregulating the high mannose glycoform content of a recombinant protein during a mammalian cell culture by manipulating the mannose to total hexose ratio in the cell culture media formulation.

Methods of protein production in continuous perfusion mammalian cell culture bioreactors are provided. Methods for continuous perfusion culture by allowing cells to self-regulate the rate of addition of perfusion medium to the bioreactor via a pH change are presented. Compositions comprising the perfusion medium as well as the process advantages of using hi-end pH control of perfusion or HIPCOP are also presented.

The invention provides culture platforms, cell media, and methods of differentiating pluriptent cells into hematopoietic cells. The invention further provides pluripotent stem cell-derived hematopoietic cells generated using the culture platforms and methods disclosed herein, which enable feed-free, monolayer culturing and in the absence of EB formation. Specifically, pluripotent stem cell-derived hematopoietic cell of this invention include, and not limited to, iHSC, definitive hemogenic endothelium, hematopoietic multipotent progenitors, T cell progenitors, NK cell progenitors, T cells, and NK cells.

The invention is directed to Haematococcus sp. KAU-01 as well as to a culture medium for Haematococcus sp. KAU-01, and to methods for using this strain to process environmental pollutants such as gases generated by coal-fired plants.

In order to induce aging while cutting the costs associated with adding cytokines at different aging stages, in a system for aging induction including a first culture chamber for perfusing, with a culture medium, a subject of aging-induction, the subject of aging-induction being derived from a living organism; a second culture chamber for perfusing, with a culture medium, a secretor that secretes a cytokine; and a control device for aging induction including a detection unit, a memory unit and a control unit, a protocol for aging induction defining a procedure of aging induction is stored, and in the control unit, an aging state of the subject of aging-induction is detected with a detection unit, and based on the protocol for aging induction, a flow rate at which the culture medium containing the cytokine secreted by the secretor is supplied to the subject of aging-induction is controlled according to the aging state of the subject of aging-induction.

Well-defined, xeno-free culture media which comprise a TGF-beta isoform or the chimera formed between IL6 and the soluble IL6 receptor (IL6RIL6), which are capable of maintaining stem cells, and particularly, human embryonic stem cells, in an undifferentiated state are provided. Also provided are cell cultures comprising the culture media and the stem cells and methods of expanding and deriving embryonic stem cells in such well-defined, xeno-free culture media. In addition, the present invention provides methods of differentiating ESCs or EBs formed therefrom for the generation of lineage specific cells.

The present disclosure pertains to compositions comprising anti-VEGF proteins and methods for producing such compositions.

The present disclosure pertains to compositions comprising anti-VEGF proteins.

We describe a cell culture medium comprising a basal medium supplemented with a CDK1/2/9 inhibitor and a Bcr-Abl/Src kinase inhibitor. The CDK1/2/9 inhibitor may comprise AZD5438 and the Bcr-Abl/Src kinase inhibitor may comprise Dasatinib. The cell culture medium may be capable of maintaining or increasing pluripotency in a cell cultured in the cell culture medium in the absence of co-culture such as feeder cells.

We describe the use of such a medium for feeder-free culture of a naïve pluripotent stem cell as well as re-programming of a primed pluripotent stem cell into a naïve pluripotent stem cell.
