Effects of puberty on the mean optical density per area unit (OD) of TrkA and p75 in Fluorogold-positive uterine-projecting sympathetic neurons of the rat thoraco-lumbar sympathetic chain

Receptor	Stage	n	OD – Median	IQR
TrkA	Prepubertal	165	127	125–139
	Peripubertal	162	121	125–140
p75	Prepubertal	150	78	82–96
	Peripubertal	150	101a	101–117

Results are expressed as median (interquartile ranges, IQR). Data pairs were compared by the Mann–Whitney non-parametric test. n = number of neurons.

^aSignificant difference in p75 (P < 0.0005) against the prepubertal stage.
