Quantification of neuron positioning defects in cxcr7b^−/− embryos rescued by cxcr7b mRNA injection

Genotype	cxcr7b mRNA dose	Mispositioned neurons per embryo	n (embryos)
cxcr7b−/−, pair no. 1, 10 somites	Uninjected	26.3	9
cxcr7b−/−, pair no. 1, 10 somites	150 pg	4.8	12
cxcr7b−/−, pair no. 2, 10 somites	Uninjected	25.3	17
cxcr7b−/−, pair no. 2, 10 somites	150 pg	8.2	23
cxcr7b−/−, pair no. 3, 12 somites	Uninjected	18.9	14
cxcr7b−/−, pair no. 3, 12 somites	150 pg	4.4	15

Neurons were categorized according to their position with respect to the MHB at the 10- or 12-somite stage. Mispositioned neurons were defined as neurons anterior or adjacent to the MHB. This table is related to Fig. S3.
