Table 2. Total cell number and apoptotic cell index (mean ± S.E.M.) in bovine blastocysts expanded or hatched cultured without and with MWNTs-exposed for 72 h.

Group	N	Total cell number	Apoptotic cell number	Apoptotic cell index (%)
Control (without MWNT)	21	425.85 ± 45.69^a	93.53 ± 19.84^a	19.74 ± 2.83^a
MWNT (0.2 μg ml⁻¹)	30	288.08 ± 36.27^b	111.64 ± 22.17^a	33.01 ± 3.72^b

Means with different superscripts within a column differ at p < 0.05 (ANOVA).

N = number of embryos.
