Retention of progenitor cell phenotype in otospheres from guinea pig and mouse cochlea

Table 1 Comparison of otosphere size parameters between treatment groups and species

Groups	EGF + bFGF	EGF + TGFα	p	Mouse*	Guinea pig*	p
Number of spheres per coverslip	9 ± 1	23.3 ± 8.5	0.044	18.5 ± 11	11.5 ± 4.9	0.458
Number of cells in each sphere	16.3 ± 4.1	37.6 ± 23.5	0.098	32.6 ± 30.5	12.5 ± 5.8	0.041

Values represent the mean ± 1 standard deviation; p is from Student's t-test; and * considers both growth factor treatment together.
