Table 4.

Colony-Forming Efficiency (CE%) of Putative Rabbit ESC Line R4 (Passage 5) with Different Feeders and LIF Supplementation

	hLIF	mLIF	rbLIF
REFs	12.40±1.48^a	7.20±3.04^ab	12.48±0.64^a
MEFs	10.80±1.17^a	14.80±1.00^a	3.84±1.61^b

^{^a,b}

Numbers with different superscripts differ significantly. The CE% was in a normal range under both conditions I (hLIF+MEFs, 10.80%) and II (rbLIF+REFs, 12.48%); however, the CE% was abnormally low under the rbLIF+MEFs condition (3.84 h).

ESC, embryonic stem cells; LIF, leukemia inhibitory factor; h, human; m, mouse; rb, rabbit; REFs, rabbit embryonic fibroblasts; MEFs, mouse embryonic fibroblasts.
