The present invention relates to a composition for preserving cells and a method for preserving cells and, more specifically, to: a composition for preserving cells, containing, as active ingredients, plant-derived recombinant human serum albumin and plant peptides, wherein the composition maintains a high cellular survival rate while maintaining animal-free and xeno-free properties and is stable without changes in cellular morphology or surface expression factors in the short-term preservation of cells such as stem cells or primary cultured cells; and a method for preserving cells by using the same.

Composition for preserving cells, containing, as active ingredients, plant-derived recombinant human serum albumin and plant peptides

A three-dimensional cell culture method on the basis of a biodegradable synthetic hydrogel is provided. The method may include culturing cells in a cell culture dish in a non-contact manner using a porous membrane and a biodegradable synthetic hydrogel in the culture of stem cells and primary cells.

Three-dimensional cell culture system and cell culture method using same

The present invention relates to a method for inducing osteogenic differentiation of mesenchymal stem cells and, more particularly, to a short-time osteogenic differentiation method of culturing cells using a porous membrane and a biodegradable synthetic biogel, whereby the cells do not contact a cell culture container. The present invention can significantly shorten the induction period of osteogenic differentiation, compared to the conventional osteogenic differentiation method, and has an effect of the cells being easily separable after differentiation as well.

Method for inducing three-dimensional osteogenic differentiation of stem cells using hydrogel

The present invention relates to a method for co-culture of stem cells using feeder cells, more particularly to a method for culturing stem cells by using a membrane having a number of pores to separate stem cells and feeder cells. In the present invention, the culture condition of stem cells optimized is provided, in which stem cells and feeder cells are cultivated independently in separate spaces while permeating essential substances selectively. The stem cells prepared in the present invention continue to remain indifferent and be supported by feeder cells until needing being sub-cultured. In addition, the stem cells even for therapeutic use can be obtained without any contaminant since not pretreated with a cytostatic agent such as mitomycin or irradiated. Therefore, the method for co-culturing stem cells by using a membrane of the present invention can be widely used for clinical applications.
