Table 2.

Pericyte and IMP self-renewal at 37°C

	# Primary Spheres	# Secondary Spheres^*	# Differentiated Spheres^**
Wild type pericytes	10	29 ± 10	15 ± 11
Wild type pericytes + ECs^a	25	49 ± 22^***	35 ± 21^***
IMPs	31	56 ± 19	25 ± 11
IMPs + ECs	45	71 ± 30^***	42 ± 25^***

Primary spheres were disrupted after two weeks (mean ± SD).

^**

Mean number of differentiated spheres in secondary sphere preparation after two weeks (n = 2 experiments, > 10 primary spheres disrupted per experiment).

^***

Significantly different from wild type pericyte and IMP cultures (P < 0.01).

5 × 10⁴ ECs were added to 10⁴ pericytes, the density of cells resuspended in stem cell medium was equal.
