US Patent:

Filed:

Jun 20, 2007

Appl. No.:

11/765831

Inventors:

Sean Palecek - Verona WI, US
Jeffrey Mohr - Madison WI, US
Juan De Pablo - Madison WI, US

International Classification:

C12N 5/02
C12M 1/16
C12N 5/08

US Classification:

435366000, 435287900, 435374000, 435395000

Abstract:

A three-dimensional microwell system that supports long term embryonic stem cell (ESCs) culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured ESCs remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel-coated, tissue culture-treated polystyrene dishes. Microwell-cultured ESCs maintain pluripotency, differentiating to each of the three embryonic germ layers. ESC aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain ESC growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct ESC differentiation by generating monodisperse EBs of a desired size and shape.

Lin Ji - Madison WI, US

International Classification:

C12N 5/06
C12M 1/00

US Classification:

435374, 4353071

Abstract:

The present invention relates to methods and structures for preparing stem cells for use in cryopreservation methods. Stem cell colonies are provided between first and second matrix portions and are exposed to a carbohydrate-containing cryoprotecting medium and a freezing medium. The methods of the invention yield cryopreserved cells that maintain cell viability and exhibit limited cell differentiation after freezing and thawing, facilitating storage, shipping and handling of embryonic stem cell stocks and lines for research and therapeutics.

Abstract:

A three-dimensional microwell system that supports long term pluripotent cell culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured pluripotent cells remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel-coated, tissue culture-treated polystyrene dishes. Microwell-cultured pluripotent cells maintain pluripotency, differentiating to each of the three embryonic germ layers. Pluripotent cell aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain pluripotent cell growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct pluripotent cell differentiation by generating monodisperse EBs of a desired size and shape. Cardiomyocyte-rich EBs are obtained from pluripotent cells cultured in microwells of defined size and shape.
