1. A method of culturing human pluripotent cells in vitro, the method comprising:
- (i) attaching human pluripotent cells to a plurality of uncoated microcarriers to form microcarrier-cell complexes, and(ii) culturing the microcarrier-cell complexes in suspension culture in the presence of a ROCK inhibitor;
(iii) passaging the cultured cells from (ii), wherein cells after passaging are pluripotent, and(iv) repeating steps (i)-(iii) through at least 7 passages;
wherein human pluripotent cells are expanded between each passage; and
whereby stable, long-term culture and expansion of human pluripotent cells is achieved in suspension in vitro.

16. A method of propagating human pluripotent cells comprising the steps of:
-
(a) providing an uncoated microcarrier; (b) allowing a human pluripotent cell to attach to the uncoated microcarrier; and (c) aggregating microcarriers with human pluripotent cells attached thereon to thereby propagate the human pluripotent cells, wherein in one or more, or all, of steps (a), (b) or (c) the microcarrier and/or cells are contacted with a ROCK Inhibitor.
