Substantially homogenous cells populations which co-express CD49c, CD90 and telomerase are made. The method provides a first hard disk drive component having at least one solder reflow channel, the at least one solder reflow channel for retaining a predeposited solder material. In the system, an ion guide is configured to transmit ions in a longitudinal axis of the ion guide and configured to trap ions in a direction transverse to the longitudinal axis via a radio frequency trapping field.
