Effects of HpPKC inhibitors or activator on micromere-specific Ca²⁺ elevation (P. lividus)

Treatments	Micromeres	Macromeres	Mesomeres
Control	0.99 ± 0.02 (24)	0.91 ± 0.01 (23)	0.92 ± 0.02 (33)
5 μM HpPKC-I	0.91 ± 0.02 (17)	0.89 ± 0.02 (16)	0.90 ± 0.02 (26)
400 nM Gö6976	1.06 ± 0.02 (5)	0.98 ± 0.03 (5)	0.96 ± 0.02 (7)
8 nM PMA	0.76 ± 0.00 (2)	0.72 ± 0.04 (2)	0.69 ± 0.03 (2)

Ca²⁺ levels of each blastomere were reported as mean ± standard deviation (SD) of the ratios of fluorescence intensity of Ca²⁺-sensitive dye (calcium green BAPTA) to the intensity of the Ca²⁺-insensitive internal control dye (rhodamine red) in the same cell. The numbers of monitored cells were given in parentheses.
