Claim Text:
1. A carrier for expansion of pluripotent stem cells, comprising: a planar substrate disc comprising a first surface and a second surface opposing the first surface and a plurality of structured indentations formed in the first surface and the second surface; wherein the first surface and the second surface are modified with gas plasma treatment, and wherein the planar substrate disc 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, wherein the height extends from a highest point of the first surface through the planar substrate disc and to a highest point of the second surface 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 0.5 mm and wherein a first structured indentation of the plurality of structured indentations is aligned with a second structured indentation of the plurality of structured indentations in the planar substrate disc such that respective bottoms of the first structured indentation and the second structured indentation are separated by a portion of the planar substrate disc.
