Cell carriers and methods for culturing cells
First Claim
1. A carrier for growing stem cells, wherein the carrier is configured to be held in a suspended state in a solution in a bioreactor, and wherein the carrier is configured to protect the stem cells from exposure to hydrodynamic shear generated by a fluid motion in the bioreactor, comprising:
- a substrate comprising two outer surfaces, wherein one or more structured indentations are present on the two outer surfaces of the substrate; and
a hydrophilic, water soluble coating material disposed and dried on the two outer surfaces,wherein the carrier has a length from about 0.2 mm to about 25 mm, a width of from about 0.2 mm to about 25 mm, and a height in a range from about 0.5 mm to about 1.2 mm, and wherein each of the structured indentations has a major axis in a range from about 0.1 mm to about 0.5 mm, a minor axis in a range from about 0.1 mm to about 0.5 mm, a depth in a range from about 0.025 mm to about 0.5 mm, and an aspect ratio in a range from about 0.1 to about 1.5, andwherein the coating material comprises a sodium chloride, and the concentration of sodium chloride is in a range from about 0.01% to about 3% by mass with respect to a mass of the carrier.

Abstract
A carrier for growing stem cells is provided, the carrier comprises a substrate comprising one or more outer surfaces; and a hydrophilic, water soluble coating material disposed and dried on one or more of the outer surfaces. The carrier comprises one or more structured indentations on one or more of the outer surfaces, wherein the carrier has a length at least about 0.2 mm, a width at least about 0.2 mm, and a height in a range from about 0.05 mm to 1.2 mm and each of the structured indentations has a major axis in a range from about 0.1 mm to 0.5 mm, a minor axis in a range from about 0.1 mm to 0.5 mm and a depth in a range from about 0.025 mm to about 0.5 mm. A method of culturing stem cells and stromal cells using the same carrier are also provided.
