Study design: Biopsies were taken from the upper edge of the hysterotomy during caesarean section (CS) at term (n = 5), in labor (n = 5) and from the corresponding area in the non-pregnant uterus after hysterectomy (n = 5). Cervical biopsies were obtained transvaginally from the anterior cervical lip. Serial cryostate sections were prepared for immunohistochemistry using polyclonal antibodies to PGP 9.5. Results: Nerve fibers displaying PGP 9.5 immunoreactivity were observed in all sections from the three groups examined. They were identified in muscle tissue, in the stroma, and around blood vessel walls. A 30- fold decline of immunoreactive nerve fibers was observed in the isthmus part of the corpus uteri at term compared to the non-pregnant. There were no significant differences between the immunoreactivity in the cervix uteri of the three groups. Conclusions: The innervation of the cervix uteri is dense and unaltered throughout pregnancy and labor. In contrast, the corpus is almost denervated. Further studies are needed to clarify the reason and the impact of these findings.展开更多

Before the advent of phenotypic markers, RGCs were normally identified using retrograde tracing of retinorecipient areas. This is an invasive technique, and its use is precluded in higher mammals such as monkeys. In the past decade, several RGC markers have been described. Here, we reviewed and analyzed the specificity of nine markers used to identify all or most RGCs, i.e., pan-RGC markers, in rats, mice, and macaques. The best markers in the three species in terms of specificity, proportion of RGCs labeled, and indicators of viability were BRN3A, expressed by vision-forming RGCs, and RBPMS, expressed by vision-and non-vision-forming RGCs. NEUN, often used to identify RGCs, was expressed by non-RGCs in the ganglion cell layer, and therefore was not RGC-specific. γ-SYN, TUJ1, and NF-L labeled the RGC axons, which impaired the detection of their somas in the central retina but would be good for studying RGC morphology. In rats, TUJ1 and NF-L were also expressed by non-RGCs. BM88, ERRβ,and PGP9.5 are rarely used as markers, but they identified most RGCs in the rats and macaques and ERRβ in mice. However, PGP9.5 was also expressed by non-RGCs in rats and macaques and BM88 and ERRβ were not suitable markers of viability.展开更多
