Single immunohistochemical staining for protein gene product 9.5 (PGP) as a neural marker revealed progressive growth and differentiation of ganglia and neurons. In 5-week-old foetuses, ganglia were small paired structures composed of oval neurons with large nuclei. By seven weeks, both ganglia and neurons increased in size and adopted a more rounded morphology. At 10 weeks, ganglia showed marked enlargement and morphological diversity, with neurons varying in shape and size. These findings indicate functional maturation of the sympathetic chain ganglia, relevant to autonomic innervation of abdominal and pelvic viscera, and may support early diagnosis of neurodevelopmental disorders and improvements in prenatal veterinary care.}, title={Histomorphological changes in lumbar sympathetic chain ganglia of the female pig during prenatal development}, type={Short communication}, URL={http://www.czasopisma.pan.pl/Content/137626/PDF-MASTER/19%20_%20Franke-Radowiecka%20_%20Short.pdf}, doi={10.24425/pjvs.2025.157283}, keywords={sympathetic chain ganglia, prenatal development, pig}, }
