摘要:
Artificial ovaries comprising porous three-dimensional scaffolds are provided. Also provided are ink compositions and methods for printing the scaffolds. The artificial ovaries have spatial arrangements and cellular compositions that allow them to mimic native ovarian tissue. As such, they can be cultured or transplanted to support female endocrine function and/or the development of oocytes and/or eggs.
摘要:
The present invention relates generally to a three-dimensional cell and tissue culture system for the female reproductive tract. In particular provided herein the system includes individual female reproductive cultures in a dynamic microfluidic setting or integrated using a microfluidic microphysiologic system. In some embodiments, the present invention provides ex-vivo female reproductive tract integration in a three dimensional (3D) microphysiologic system.
摘要:
A serum free cell culture media, wherein the media is adapted to be conditioned by culturing a first set of eukaryotic cells in the media, wherein the first set of eukaryotic cells use an expression vector to excrete levels of desired complex proteins into the media; wherein said desired complex proteins include human Growth Hormone (hGH), Growth Hormone-like growth factors, insulin-like growth factors, insulin, modified insulins, cytokines, mitogenic proteases and mixtures thereof; and wherein the media is adapted to grow a set of eukaryotic cells.

Methods are provided for obtaining expanded human cord blood cells or cord tissue cells expressing CD34. The methods involve seeding a sufficient amount of human cord blood cells or cord tissue cells with a sufficient amount of menstrual cells under co-culture conditions suitable to promote expansion of the cord cells, and co-culturing the cord cells with the menstrual cells under culture conditions that support at least two or more population doublings of the cord cells. Methods are also provided for growing expanded human cord cells to give rise to any one of colony forming units, colony forming unit granulocyte macrophages (CFU-GM), burst forming unit erythroids (BFU-E), and colony forming unit granulocyte erythrocyte macrophage megakaryocyte (CFU-GEMM) blood lineage precursor cells. The expanded cells may express CD34, SSEA-4, and HLA-II. Compositions of the expanded cells are also provided.
摘要:
The present invention relates to a method for preparing Langerhans cells or interstitial dendritic cells or both from CD14+ monocytes stemming from the peripheral circulatory blood of a living being, wherein the method comprises differentiation of CD 14+ monocytes into either Langerhans cells, interstitial dendritic cells, or into both types of cells by placing the CD14+ monocytes in the presence of a cell environment comprising epithelial cells and/or mesenchymatous cells.The present invention also relates to cell or tissue models comprising such prepared Langerhans cells and/or interstitial dendritic cells, and optionally macrophages and endothelial cells, and to the uses of such cell or tissue models.
摘要:
Methods and cell culture medium for the generation of human pluripotent embryonic stem cells are disclosed. Human embryonic stem cells are cultured with human granulosa feeder cells, muscle cells, Fallopian ductal epithelial cells, bone marrow stromal cells, and skin fibroblasts and the embryonic stem cells maintain their pluripotent phenotype. The human pluripotent embryonic stem cells can be cultured without feeder cells, and in the presence of supplemental growth factors. The human pluripotent embryonic stem cells can be alternatively cultured with conditioned medium obtained from a cell culture capable of maintaining human embryonic stem cells in a pluripotent state, wherein the cell culture is a human granulosa cell culture.

摘要:
The invention provides methods for generating customized hESC and lines thereof for future use in the treatment of genetic relations. In one aspect, the customized hESC lines are grown using feeder cells from biologically or genetic relations in order to avoid contamination by foreign pathogens or exposure to foreign antigens.
摘要:
The invention provides an in vitro culture medium for in vitro-produced porcine embryo for the in vitro culture thereof, which can improve the quality of the resulting blastocyst and can raise the ratio of the development into fetus and infant after transfer, along with a method for in vitro culturing in vitro-produced porcine embryo using the culture medium, which can improve the quality of the resulting blastocyst and can develop the blastocyst into fetus and infant after transfer.A culture medium for the in vitro culture of in vitro-produced porcine embryo, which contains lactic acid and pyruvic acid; a culture medium for the in vitro culture, which is conditioned with oviductal epithelial cell; and a method for in vitro culturing in vitro-produced porcine embryo, comprising culturing the in vitro-produced porcine embryo using the culture medium for the 0 to 2-day term after fertilization and subsequently culturing the embryo in a glucose-containing culture medium.
