FIG. 2.

(A) Enrichment of CD34⁺ cells from mouse tissue-derived epidermal cells using microfluidic cell capture devices with the Array 1 design. Single stage CD71⁺ cell depletion and single-stage CD34⁺ positive selection result in comparable, 4–5-fold enrichment. The two-stage configuration only provides modest improvement. *indicates p<0.5. (B) Enrichment of CD34⁺ cells from mouse tissue-derived epidermal cells using microfluidic cell capture devices with the Array 2 design. Unlike the Array 1 design, the two-stage configuration shows an additive enrichment.
