The present disclosure relates to a medium composition for culturing stem cells, and more specifically, to a medium composition for culturing mesenchymal stem cells, in which the medium composition includes a basic medium in which various quasi-completed mediums (DMEM, α-MEM, IMDM, F12, and DMEM/F12) are mixed, L-ascorbic acid 2-phosphate, fetal bovine serum, basic fibroblast growth factors (b-FGF), insulin, N-acetyl-L-cysteine, calcium chloride, and hydrocortisone.

According to the present disclosure, it is capable of improving proliferation ability and differentiation ability of the mesenchymal stem cells, and is capable of producing cell therapy products more economically using the mesenchymal stem cells by enabling the mesenchymal stem cells to be cultured at a low price compared to the existing culturing methods.

The present invention relates to the field of plant breeding and in particular to the regeneration of plants from cells and other tissues. More particularly, the invention provides methods and means for improving callus and shoot formation and regeneration of plants using hyperphyllin or derivatives thereof.

The present invention provides: a lubricin-localized cartilage-like tissue characterized in that, when in an arbitrary cross section passing a first center of mass of a cartilage-like tissue derived from pluripotent stem cells or a center-of-mass region, which is a portion inside a concentric sphere being centered at the first center of mass and having a diameter of [first major diameter×0.2], the expression level of lubricin per unit area contained in a central region, which is a portion inside a concentric circle being centered at a second center of mass that is the center of mass of the cross section and having a diameter of [major diameter of cross section (second major diameter)×(0.4 to 0.9)] is referred to as the central lubricin level and the expression level of lubricin per unit area contained in the non-central region is referred to as the non-central lubricin level.

Provided herein, inter alia, are compositions and methods for culturing mammalian cells. In certain aspects, the composition is a medium containing one or more of a lithium ion source, one or more fatty acids, and/or ethanol. Use of any of the cell culture media described herein to culture cells that have been genetically engineered to produce one or more recombinant polypeptides (for example, antibodies) can result in increased titers, a more favorable glycosylation profile, and/or modulated (e.g. decreased) amounts of high and low molecular weight species, and/or modulated (e.g. decreased) amounts of acidic or basic charge variants, compared to cells cultured in a medium that does not contain one or more of a lithium ion source, one or more fatty acids, and/or ethanol.

This invention provides a system for efficiently producing differentiated cells from pluripotent cells, such as human embryonic stem cells. Rather than permitting the cells to form embryoid bodies according to established techniques, differentiation is effected directly in monolayer culture on a suitable solid surface. The cells are either plated directly onto a differentiation-promoting surface, or grown initially on the solid surface in the absence of feeder cells and then exchanged into a medium that assists in the differentiation process. The solid surface and the culture medium can be chosen to direct differentiation down a particular pathway, generating a cell population that is remarkably uniform. The methodology is well adapted to bulk production of committed precursor and terminally differentiated cells for use in drug screening or regenerative medicine.

This invention relates to the in vitro differentiation of pluripotent cells into pancreatic progenitors by i) culturing pluripotent cells in a definitive endoderm (DE) medium comprising a TGFp ligand, fibroblast growth factor (FGF), bone morphogenetic protein (BMP), a PI3K inhibitor and optionally a GSK3 β inhibitor to produce a population of definitive endoderm cells, ii) culturing the definitive endoderm cells in a first pancreatic medium comprising an activin antagonist; FGF; retinoic acid; and a BMP inhibitor to produce a population of dorsal foregut cells; iii) culturing the dorsal foregut cells in a second pancreatic medium comprising FGF, retinoic acid, a BMP inhibitor, and a hedgehog signalling inhibitor, and; iv) culturing the endoderm cells in a third pancreatic medium comprising FGF. The progenitor cells thus produced may be further differentiated into pancreatic endocrine cells. These methods may be useful, for example, in producing pancreatic cells for therapy or disease modelling.

Disclosed herein are albumin compositions having defined fatty acid profiles and methods of using the same. The albumin compositions described herein are suitable for use in cell culture methods, protein stabilization methods, amongst others. The albumin compositions described herein may improve the viability of and/or promote the growth of cells (e.g., mammalian cells) when the cells are cultured in a medium containing the albumin compositions. The albumin compositions described herein may improve the stability of a biologic when the biologic is in the presence of the albumin compositions. Further provided herein are methods of formulating albumin compositions having defined fatty acid profiles as described herein.

A method for culturing placental potential cell is provided, comprising steps of: (1) obtaining placental cells and/or tissue under aseptic condition; (2) inoculating the placental cells and/or the tissue in a culture medium for culturing, adding cell growth regulators to the culture medium, in such a manner that the placental potential cells grows to make the placental cells and/or the tissue into a proliferative state; (3) culturing the placental potential cells to make the placental potential cells proliferate continuously into cells with characteristics of stem cells. The present invention not only finds the source of human tissues, organs and the continuation of their function, i.e., regenerative potential cells; but also finds a medical and health longevity method, but also finds out the life materials to maintain and support the potential cells, so as to replace drugs with the living material.

Disclosed are compositions and methods for the preservation, storage, and transport of living biological tissues, organs, and populations of isolated cells. In particular, the disclosed compositions and processes permit mammalian cells, tissues, and organs to be harvested from suitable donor animals, stored for prolonged periods, and transported to the site of recipient implantation, all without significant loss of cell viability, biological activity, and/or tissue integrity.

The invention provides a defined low protein culture medium for maintaining cells in an undifferentiated state, the medium comprising: a basal medium, an organic acid from the tricarboxylic acid cycle, nonessential amino acids, a combination of growth factors selected from the group consisting of FGF-2 protein, an IGF-1 protein or insulin, a Transferrin protein, and a TGF beta 1 protein, wherein the medium is essentially feeder-free, essentially xeno-free, essentially free of beta-mercaptoethanol, and essentially free of animal-derived or human-derived proteins.
